Ford F-150 - 1997-2003 :: 4R70W Shift To Neutral Between 2 - 3 Then Drop Into Gear
Mar 14, 2013
4R70W. This one is in my 99 F-150 with the 4.6. From what the previous owner told me this trans only has 13k miles on the rebuild and I believe him because the converter is bright blue and when it does shift right, the shifts are solid and fluid is very clean. Truck only has 98k miles on the body as well, so it's possible the truck did sit a while because my tires have a ton of tread on them, but they are dry rotted a bit (dated 2006 IIRC).
Issue: When the trans is cold (sat overnight) it will shift to neutral between the 2-3 shift for 1-3 seconds depending on outside temperature and then drop into gear. But it only does this for the first 30 seconds or so of driving, after that it shifts normal (although it does seem to hold gears a little longer than I would think it should on occasion and not upshift). I have only gotten it to do it once per cold start so it seems like once the trans gets any heat it's fine.
I was also thinking I was getting drain back and maybe it wasn't heat related so I dropped the pan, replaced the filter, fluid and pan seal (it had a small leak) and torqued the valve body. Two of the bolts were a little loose, but the rest were fine. Tightened them to spec and put it back together with no dice. Truck also gets pretty bad fuel mileage so I'm starting to think maybe there is some temp sensor screwing everything up?

My 4r70w is having some issues. It drives/shifts fine in reverse, 1st and 2nd but wont shift past 2nd gear. Doesn't even act like it tries. No CEL. I dropped the pan yesterday and there wasn't any metal chunks or any other debris in the pan and only the normal fuzzes on the magnet and there wasn't even an abundant amount on the magnet. This is a junkyard trans that was put in before I purchased the truck (2001 F150 supercrew 2wd).
I've ohm'd the shift solenoids and they seem to be within spec (below 30 ohms) so i want to rule them out, but still thinking of replacing all 3 solenoids just to be safe. Also, the filter just fell out with the pan so I'm assuming that might be part of the problem. My next thing to check is the 2-3 accumulator and spring to see if its stuck or broken.

Do I have to drop the valve body to get to the shift solenoid? Is there only one solenoid? Anything special or tricky I should know about?

The problem started with a front seal leak a few months ago which I had no choice but to continue driving with because of low funds. I don't drive much so a couple of quarts of ATF was usually enough to get me out and about for what little driving I had to do. I know.. a front seal is cheap, but I'm partially disabled and unable to work on anything that is not under the hood.
I finally scraped up enough money to hire a friend to replace the seal, but he had a life crisis before completing the work, so I had to get another friend to reinstall the trany... still had the leak, but I could get around by adding ATF as before.
So we tried again... dropped everything and put another new seal on. This stopped the leak, but we got some grinding/squealing noises and could not get the trany to engage any gear.
From reading forum posts and other sources, we decided to replace the TC which we just completed this evening. We got some more of the grinding / squealing noise like before, except that it only occurred the first time we tried cranking the engine, the 2nd time we got no noises, but again no gears engaging.
What to check/replace next assuming there is something we can look at other than a total trany rebuild or replacement. I personally find it hard to believe we could have gone from a tolerably functional trany to scrap metal just replacing a seal and the TC. Its gotta be something simple we overlooked !!

The truck:
2000 4X2 F150
4.2l V6
280k miles/ some towing
The problem : The trans has a hard time getting into 1st gear. When you put it into gear you have to rev it to about 3k (when it's warm, 4k when cold) RPMs at which time you feel a definite engagement and it goes through the rest of the gears just fine. Once it's warm it will do stop and go traffic as long as you start it with the OD off.
The background : Orobably the stock motorcraft filter on there, and I don't think the oil has been changed in the life of the trans, but I do know that it's never been ran low on fluid. I took a gander at it and found a plug where a gear type speedo went on older models to be loose and leaking. tightened it up about two full turns. also noticed what looks to be a leak where the main case meets the output shaft housing. now I know neither of these are the cause of my headache but I do wonder if the second leak might be a sign.
The research : I've been looking for almost a week now for a solution. I've been all over TCCoA, Explorer Forum,10 pages of search here on FTE and various other Ford based websites and have come across a single thread with the same symptoms but the OP never came back with a solution.
The plan : A fluid/filter change (and flush) is definitely in the plans as well as inline filter for my own satisfaction. from what I've read the stock 1-2 accumulator is known to go bad on some of these and if I have the pan off might as well check anyways.

Working on a 2004 E-250 van. [URL] ....
I went through this transmission completely, its back in the van and I get no 1-2 shift.
when I first put it together, I missed the hole in the flex plate for the torque converter stud and started tightening the bell housing bolts down, I heard loud "POP" and realized what I had done. maybe I damaged the pump?
forward and reverse engagement is firm, both give a nice bump when it goes in gear. This tells me the forward clutch is working, but the intermediate clutch is not applying to make second gear happen.
I have done all the easy stuff I can think of, replaced the shift solenoid and put in a new 1-2 accumulator piston. I guess i need to air check the intermediate clutch piston again and make sure its applying. this a 2004 model trans, so it has the new style pump and intermediate piston.

I have a 2005 ford expedition with 91000 miles, it has the 5.4 w/ the 4r70w transmission.
For some reason when my truck tries to shift into 4th gear, the RPM's climb to approx. 3000 rpms (meanwhile the truck is not gaining speed) and slowly drops down to about 1000-1500. once the rpms drop down fourth gear eventually engages and I can go about my business as normal as long as I do not let my mph drop too low.
If I turn O/D off, the truck drives perfect, minus not having overdrive.
If I come to a dead stop and put the truck in 2nd gear, with O/D on the truck drives great and it has good engine braking so I am assuming that the band is holding.
I took it to a transmission shop to have some diagnostic checks done, they told me that fourth gear was barely engaging and that they would have to tear apart the transmission to diagnose it further, I told them not to disassemble the transmission.
So I changed out the torque converter (which I assumed was "fourth gear") and changed out all the fluid, the fluid looked a little burnt but there was no debris in the pan but there was some silver material on the tranny pan magnet, and installed a new filter. and the problem still exists.

My truck is making this chattering when I shift down or just sitting there in neutral it goes away when I press the clutch or if I push the shifter in the spot before the gear I was told it was a throw out baring but I'm not sure I herd this transmission will start to chatter before it goes out so what to do?

I have a 1997 F-150, 2 wheel drive, 4.6L truck. Recently the transmission got to where it didn't shift properly. Then it got to where, after driving it about 10 to 15 miles the transmission would drop out of gear with the transmission selector in drive.
I have replaced the transmission sensor, the rear end sensor and it still does the same thing. Drive about 10 to 15 miles and, with the transmission selector in drive the truck will not pull. The motor can be rev'ed but the truck won't move just like it was in neutral.
What is wrong. The transmission shifts fine, the truck runs fine, but after 10 to 15 miles the transmission quits working.

I have a 1997 forkd F150 with a 4.6L Romeo engine. I have recently rebuilt the engine and now since it is put back together I am having a issues that i cannot pin point. When the truck is running and in gear my RPM drop to around 500 or below and my oil pressure drops and comes back up when the rpm's come back up this an intermittent problem and I have replaced the IAC valve and every once in a while i get a P0401 code for the exhaust recirculation. I think I am loosing some kind of vacuum. It was not doing this when I tore into the truck. It seems to be running okay not hesitation.

Anyway, I'm gimped in my left shoulder for a while and I'm trying to do what i can with my 03 F150 Supercrew /4bt Cummins conversion. I am using a Dodge 47rh tranny and need to know the wiring for the 4R70W so I can hook up my 12 + ignition wire, back-up lights and neutral safety switch. I'd like to build my wiring harness.

I have a 2001 Ford F-150 5.4L Supercrew that won't seem to shift out of 1st gear. This morning coming out of stop light on the way to work, the truck seemed to jerk when it was supposed to shift into 2nd gear. I was told by a friend that the speed sensor may be it?
So I took the truck around the block just so I can get a feel for what is going on. So the truck shifts into 2nd, but not past that. It seems that around 30mph the RPM's go up jump up quickly to 2k+ and no shift or increase in speed. I was reading up a bit on it and came across the possibility of a TPS?

99 F150, 4x4, 5.4L, 4R70W trans.
I am experiencing a shudder at speeds between 45 and 50 when trying to accelerate mildly - it usually occurs after slowing down from a higher speed.
It is similar to the bucking that occurs when you do not downshift a manual trans.
I am guessing that it is the torque convert clutch staying locked or the tranny staying in OD too long. The shudder will go away if I give the truck enough throttle to downshift or simply push the overdrive off button - which forces it to downshift to drive.
What is the probable cause?

here is the full story. just gotten truck out of the shop for a lower end rebuild and diff rebuild, truck set for about 5 to 6 months with no battery or motor. Engine runs great! besides a P1000 code.
I can drive down the road and can't go no faster then about 40mph without going to or over 3grand on the tac. I took it to auto parts store and gotten codes for both shift sol. and found out that the internal wiring harness was bad, and replaced it today. and cleared the codes. left parts store truck went shifted to 2nd and started to seem like it was going to go into 3rd then the rpm's went up like I was getting on the pedal when I wasn't and now it is going the same thing again. but took it back to parts store and checked for any codes and just got P1000 code and code about my speed sensors but they have been bad for a while.

I have a '97 F150 Lariat Ext cab, 5.4, 2Wd, 175K, a bit rusty but for the most part functional. Unit is parked for long periods of time.
3 - 4 years back the gear shift did not want to go into PARK and and the gear indicator was out of register. Unit would not start and I had to move shift lever to N to start. Fixed the two screws on shift plate/column per this site. Then 18 months ago same thing begin to occur but this time I used blue thread lock to hold screws in place. Still had to throw into park to get it to stay.
6 months ago shifter became very difficult to move and near impossible to get into PARK. When in PARK the interlock must have not been engaged so had to move to N or push lever hard into PARK to start.
Tired of this so I cruised the site and found several posts on taking dash apart, repairing a broken shift tube and or replacing bushings.
Battery disconnected, dash apart, cluster out, steering wheel still on and steering column still in position. Shift tube appears OK, i.e. not broken as in one post, bushings appears OK as there is no play or slop evident, but I cannot get the shift lever to move from PARK, period.
When the shift lever is pulled toward the wheel, a pawl on the tube causes a plastic or nylon arm to move about 90 degrees. It must be a stop or safety of some sort. I have not dug deep enough to see the shift plate with the two screws. At 75 I find it difficult to lay upside down to reach and hope I can get to them from the top.
Questions:
1. How do I get it out of PARK to check all things on shift tube and gear selector units?
2. Does the battery need to be connected for the interlocks to function?
3. Do I need to drop the column to check on shift tube items?
4. With a rusty trans, can the shift cable to trans connection be the problem?
5. What to look for, how to repair. etc.

I have a 98 f150 with 4.6l an 4r70w trans. I am on my second flex plate when I pulled the trans this time the tc was stuck to flex plate an the center of flex plate was busted around the bolts it has the remo engine in it but the studs on the tc were stuck in the flexplate I got them apart but it looked as if holes were off center on studs orded new tc an flex plate again. There is 1 bolt missing in top of housing an one was to long an didn't tighten up could that cause it to do it...

I just bought a f150 2001 5.4L crew cab. It has the O/D switch in the gear shift lever and the black plastic handle is broke. I found a complete replacement lever on ebay but cannot find any tutorials on how to replace this.

1997 F150 xlt 4x4 ... When I shift the gear shift lever to below D (2-1) it blows a fuse and I lose instruments. Replacing the fuse is not difficult, just tiresome..

I have a 2000 F150 5.4l 4x4. When I am going over 50 on the highway and I am in OD, if I let off the gas a couple of seconds later it feels as though the brakes come on because the truck slow down so drastically and when I give it a little gas it slams into gear. It feels as like there is a "gap" where nothing is engaged before it slams back in. This is a rebuilt tranny with less than 7K miles on it. I took it back once and they said it was the motor mounts. I had those replaced and still the same problem. I replaced the spark plugs 6K miles ago and the COPs 3K ago. There is 170K on the truck. I only drive about 8K miles a year.

The Speed Needle works fine. But...the Odometer part quit some time ago. I can't tell what my fuel Mileage is now. How to troubleshoot this problem?
Things that might affect this problem; Transmission skids loudly when going in and out of 4-OD. It could be the Torque converter clutch?
The Gear shift lever is sloppy. Doesn't fill me with Confidence.
Brake fluid warning light is on most of the time. Fluid level is up hi though. Driver door mirror control switch don't work in one direction Who on this Forum has a Switch for me?

1993 Geo Prizm with some odd 275,000 miles on it. Was at a stop sign, in first gear, and gave the car some gas. Very quickly it jumped out of first gear and stopped moving abruptly. Tried to get it back in first gear and it just stayed in neutral. Had to push it to the side of the road. Tried putting it in any gear and it wouldn't go. Then tried to have the car running in neutral and let up on the clutch and as soon as I started letting up on the clutch, something (like metal) started grinding. Pushing the clutch it (in neutral) stops the grinding. So, do I need a new clutch? New transmission?
