Ford Transmission :: 4R70W - No First To Second Gear Shift
Jul 27, 2013
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 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.

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?

I just put a rebuilt 4r70w in my '97 expedition and it shifts good but in 4th gear when I let off of the accelerator it starts to shudder until it shifts to 3rd. It acts like it is freewheeling then catches on and off. My thoughts so far is that I don't have the digital transmission range sensor positioned right or the overdrive servo isn't working properly.

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 !!

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?

I have a Ranger that I have put a 302 engine with an FMX transmission in...everything seems to be working correct except the transmission will not shift in to 3rd gear... don't know alot about transmission.. could this be a linkage adjustment issue?

98 ford expedition 4.6 2wd, 4r70w only reverse works. Here's the low down on what happen.
First off the truck overheated a little then was cooled off and coolant added. about a week later it wouldn't go forward so i told my wife to check the tranny fluid it was low barely on the dipstick, fluid was added and she was on her way. this past weekend the truck sherd all 5 lugnuts on the driver rear wheel. fixed that but went to drive it away and the tranny was slipping a little. added 2 quarts to fill and on the way again. 3 days later went to drive it to my dads shop to find out where the fluid is going, its slips again, added 2 quarts to fill just to drive 6 miles.
It drives fine until i get to my destination we have to stop to open a gate, i put in neutral to roll back to open the gate and no forward gears, only revers. i drive backwards to the shop about 300' and the tranny is empty again. looks like the fluid is going into the radiator which i'm sure caused the overheating a couple weeks back. no water is getting into the tranny. I've changed the filter and fluid and radiator, but still no forward gears only reverse. could there be an easy fix, electrical part maybe or mechanical or do you think its trashed and need replacing.

I've been making steady progress tearing down the transmission from my 2002 E-150 but have reached a point that I can't continue. The ATSG AODE manual says to "Rotate the shell assembly to align indent with overdrive anchor pin and then Remove forward sun gear." This is the step right after removing the intermediate stub shaft.
Well, the stub shaft came right out but the shell will not rotate, move, or do anything. It certainly cannot be removed. How to get this out?
Background: The trans is being worked on due to a failure that prevented it from being driven and it actually stalled the engine when shifted into any forward gear. It would idle in park or neutral. It would also still allow the engine to run in reverse but the van would still not move. I was able to push it into the garage in neutral.

I have a 98 expedition with a 4.2 liter 4x4 and what I believe to be a 4r70w transmission (u code on the door sticker)
The original transmission went at 105k miles and was replaced with a new factory ford transmission by a ford dealer 3.5 years ago. The new transmission only has 10k miles on it.
Now the new transmission only has reverse. reverse works like normal but no forward gears. the idle will change when i put if in gear, but will not move, acts like it is in N . There is no strange noises.
It's hard to believe a new trany is shot already, no towing, or off road use.
My question is : is there ANYTHING that can go bad that would cause this? The trany fluid is clean and clear bright red, and no burnt smell.
I want to check everything I can before calling a tow truck to have it looked at. I will have it repaired if needed, but I don't think I want to replace another tranny.

I have a 36 foot motor home on a 2000 Ford F53 chassis. (similar to single axle freight trucks and school busses) After getting one set of the rear wheels partially stuck, which resulted in some spinning of that side, the overdrive off light on the shift lever began to blink and the service engine soon light came on. The fault code said, "speed sensor showing more than one mile per hour". Now the automatic transmission sometimes will not shift into first gear after stopping and has to be manually downshifted, after which, it works fine.

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.

I have a 1997 Mercury Mountaineer with a 4R70W trans behind a 5.0 liter. Vehicle sat for about 5 months. Went out to put it back on the road, and now the trans seems to be stuck in a forward gear no matter what the selector is in, park, reverse, neutral. Dropped the pan and replaced the filter and replaced what fluid was drained. no difference,.

Situation is I have a 92 F150 2WD donor truck. 5.8l will be going into my 80 F150 4X4. E4OD transmission is long gone, but I do have a 4R70W from a 96 Explorer. Bolting it together is no problem, but there are differences in the transmission controls. E4OD uses a coast clutch, 4R70W does not. EPC, shift solenoids and TCC are compatible. I do not want to use a 5.0l PCM or add external controllers like the Baumannator.
Question is, can I control the 4R70W with the PCM that comes with the 5.8l?
I'm thinking I can ignore the coast clutch output, maybe tie it to +12 through a resistor if that makes the PCM happy. Baumann's controller appears to work with E4OD's as well as 4R70w's doing exactly this. Baumannator TCS Electronic Transmission Wiring Details....

I have a 2007 e-150 ford van with only 38,000 miles on it, with i believe a 4r70w transmission. The problem started yesterday. Going in reverse, it would go, but as soon as you take the foot of the gas, it would stop immediately, plus very difficult until it would start rolling, I think this is called engine breaking. Also, in Park, revving the engine, the trans makes a very strange noise, and wants to creep up (move forward) with more gas you give it. neutral does the same thing. When i drive the van, it seems like it switches gears fine, and does not make any noise, but the OD light does not show when you press the button. I did check the fluid, nice and red/pink color no smell at all. No leaks under the car, and the trans is totally dry all around. I do not show a check engine light on. This morning my friend came over with his scanner and hooked it up to my van's plug. It showed no codes of anything wrong. What might be wrong with the trans? My friend seems to think it might be a solenoid problem, I sort of think it might be a shifting problem, but i am no mechanic.

Its a 2004 f 150 5.4 2 wd auto, I think is a 4r70w, when I first start out in the morning I get a trans malfunction on the dash and the od light flashes, if I shut the truck off and restart it goes away for the rest of the day, when it does this the speedometer doesn't work right, vss?

I have a 2000 Excursion w/ V10 and I have an issue with the transmission form time to time. some times it does not want to shift out of first. if I pull over and turn it off for a few minutes it will be fine for a while and it doesn't do this all the time. A few nights ago it did this so I pulled over and turned it off and it still did it but then it started shifting on its own just fine till we got on the high way which is started shifting in and out of over drive going around 60-65 MPH. didn't want to go too fast not knowing what it could or would do. it did this for a few miles then it started working fine. next day it did the same thing not wanting to shift out of first then started working fine. drove it around last night and it all worked perfectly. The CEL is on but I get a no communication text from the scanner so that is another thing I need to look in to. I'm guessing it is an electrical issue being when it works it shifts fine and it does not slip at all.

Well I Took my truck (1985 F250 6.9L IDI C6) and went through a little mud bog got some water in the tranny, no biggy i flushed the fluids out a couple times and went to drive it. But now it wont shift from 1st to 2nd but i can manually shift it from 1-2 I replaced the Modulator and that havent made a difference. Is there anything I should look into?

On my 96' F-250 4x4, The tranny will shift to 3rd gear and that's it. If I put it in Neutral and then back into drive it will stay in 4th gear for about 15 seconds then go back to 3rd. What could be causing that?
