Ford Transmission :: C6 Won't Shift Up Into 3rd?
Apr 18, 2016
I just rebuilt the 390 in my 70 pickup and the c6 came out with it. I didn't touch the trans besides putting a new front seal on it, but now that I have the truck moving again, I don't get high gear. First to second shift is decent, even though I had to wire the kickdown down so I could drive it until I could get the holley kickdown extension. But I can give it full goose and the trans just won't give me 3rd. Even if I shift it manually it won't give me 3rd.

This is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.

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?

I recently did a C6 rebuild on my 78 4X4. After the rebuild, when I go for a drive, the transmission does not AUTOMATICALLY shift out of 1st.
1. I can shift MANUALLY from 1st to 2nd with no problem, but it never goes into 3rd in D. If it was a system pressure issue, I suspect that I couldn't engage at all?
2. In Drive it just seems to be in 1st the whole time no matter how high the rpm.
3. I checked the vacuum at the modulator and I get 18 in .
4. I have tried every color modulator band and have the black one in now.
5. During the rebuild, I cleaned the governor, so I don't think it would be jammed up since it wouldn't shift even when I first drove it.
6. During the rebuild, I cleaned the valve body.
7. I confirmed the kick down is free.
8. I get a hard shift in reverse and from 2nd to 1st, but when I go to Drive, and then second, I dont notice a hard kick. Could it be that I messed up the orientation of the front clutch seal? (I hope this isn't the case!)
Here is the last couple of things I can do:
1. Could the intermediate band be the issue if I can shift in manual if it's not shifting hard?
2. The mechanic said it could still be a governor gunked up, but I'm skeptical since it never worked after the cleaning.
3. The filter screen pan from the rebuild seems to sit higher than the original that has a pipe that hangs lower. Is this the suction or the return from the system. If it's the suction I can put the original in.
Is it bad to drive her in manual if I need to? Obviously I'll keep the speed low since I can't get into 3rd. When I air pressure tested the transmission before the install, everything engaged like it was supposed to and all of my clearances were solid.

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.

I bought a truck a week ago and finally got it running. I got into the truck put it into drive and nothing happened. It is a 59 2wd with an automatic transmission. All the linkages are moving all the way to the transmission. There is a second arm coming out of the transmission in the same spot where it is hooked up now. Should it be hooked up to something? Is the transmission done for?

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.

My 85 300 cid with a C6 trans won't shift out of first. Seems like this happened several years ago and it was a vacuum diaphragm or something like that. Is this user fixable or do I need a transmission shop to look at it?

I asked a question about the E40D a while back about a hard 1-2 shift. However, I needed to replace the shift lever to get my OD light operational again. I fixed it and the issue seemed to stop for a while, so I just forgot about it. It's back again, last time it did it, it was hard enough to make the whole truck almost buck. It was a real good bang. So, could this be the 1-2 accumulator piston or the bore it resides in?
The next question I had is how long should an E40D take to shift from second to third? I've noticed on a steep onramp with some throttle, mine can have around 2.5-3 seconds of rev before it finally shifts (unloaded). I could of sworn I watched the tach climb a hundred revs or so during this once (real steep onramp), however maybe I was just dreaming, as I've never replicated it. Just wanted some opinion on this, wondering if I need to start putting some funds aside.
The truck has about 139K and the transmission looks to be original. It was used to haul a camper and a boat most of it's life, or at least that's what I was told.

I gotta 93 f150 XL it has a 4.9L and a T18 borg Werner trans. I replaced the clutch,throw out bearing, pressure plate and pilot bearing and after reinstalling trans I am unable to go through my gears.
If truck is off I can shift into some gears sometimes but not without a lot of resistance. Also some gears will let me in easy, then fight me as I try to back into neutral.
Truck starts right up but if I start in neutral I can't shift into any gears and get a lot of grinding when I try to put it in gear.
If I start in gear it drives in the gear but I have to force back into neutral. And then I'm stuck in neutral again.
It is a hydraulic clutch and fluid is full and there are no visible leaks. I am 100% sure clutch disc is facing correct way as I triple checked it while installing.

My T18 tranny in my 85 F150 will not shift, first instinct was clutch but after tearing the drivetrain out of the truck to check the clutch, there is virtually no wear on it. Slave cylinder is leaking a little bit but the mechanic that took a quick look at it said it was still working. She was shifting fine when i left for school, then when i got off the highway i couldn't shift.

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.

I have a 2003 excursion with the V10. at the hunting camp I drove it into some water without knowing my neighbor had gotten stuck and left a BIG hole. It took an hour to pull it out with a tractor. The water was up to the floor boards. afterward the transmission would not shift past second. The OD light blinks. I left it for two days to dry out. Still no good. What I need to do to get it back going?

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.
