Ford Transmission :: 4r70w - Truck Tries To Shift Into 4th Gear
Jul 16, 2013
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.

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 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.

One day I was driving my truck 96 f150 4x4 Eddie Bauer edition and the over drive light started flashing and the truck got jerky going up hills. I got home and hooked my code reader up and (p0708) it said transmission range sensor. I replaced that the next day and drove it around town for about 30 minutes and parked it all seemed to good. But the very next day I started down the road and the transmission was slipping very bad after I turned around after a few hundred feet I barley made it back to my house. I checked my transmission fluid it's full and doesn't smell burnt or anything, I double checked the alignment on the neutral safety switch I just installed and it still in line. So I'm thinking my transmission is going out...

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 !!

Reverse band broke in my C4, I took it apart enough to get the rear band out and then reassembled. Everything to my knowledge was seated correctly and the front pump seated flush with the case when I reinstalled (which is supposedly a sign that it is all seated correctly). I adjusted the bands to spec and replaced the vacuum modulator and torque converter. These were the only things replaced besides the reverse/low band. Vac modulator was replaced to original (yellow band) as I was running an adjustable before. TC was replaced just because I did not the last time I had the trans rebuilt in 2003....decided to go ahead and R&R.
I got everything assembled, filled up with fluid and no leaks. I start it up and once i finished topping it off, the truck moves forward in every gear... including park! It also seems that I'm missing a shift detent. I have P, R, N, D, 2 but no 1. I disconnected the shift linkage and tried manually shifting from the trans and have the same issue.
I did not open up the valve body, just unbolted and replaced. When you start it up, it doesn't jump forward (while in park) but when you rev it up it sounds like the motor is under load. I've consulted my Haynes C4 book and an extensive google search and no way...

97 Silverado - 5.7 with 4l60e trans. truck will not shift into 2nd gear while driving. stays in first gear until rpm are high and shifts into 3rd. under hard acceleration will stay in 1st until let off gas then shift into 3rd. manual shifting results in same, no 2nd gear until selector is moved into 3rd then shifts into 3rd. Haven't got any trans codes, fluid change netted no change in performance, fluid was pretty dirty but didn't smell burned, and there were no metal shavings in pan.

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 recently purchased a 1999 F150 with a v-6, standard transmission (5 speed). Previous owner said he had just replaced the clutch. Here is the problem, after the truck has been running a while and after stopping the truck will not shift into gear. It does not grind or make any noise, it just won't go into any gear. The only solution is to shut the engine off, place it in gear and restart the engine. During normal travel the transmission shifts up and down without any problems. The clutch does have a slave cylinder.

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?

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.

My truck gear shift is stuck in Park (console type). I have been reading threads that discuss potential causes such as blown fuses, bad brake switch, bad brake shift interlock actuator, and even ignition switch. All fuses are okay. Before I try to get into all the other possibilities, I have a question around what the local auto parts worker suggested. He said that there is a small plastic piece that may have slipped down interfering with gear movement. This could make sense, especially since the white manual release lever doesn't seem to be moving.

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.

I am using my son's truck this week, 2012 F250, 120,000 miles or so. I left it running in the drive while I got something from inside the house. Guess it was idling approximately 10 minutes. When I put it in reverse the transmission would not shift and the truck didn't move. I killed it, re-cranked it and it went in reverse.
As I was driving down the road the transmission would change gears up and down for no reason. I stopped the truck, and put it in park. I would put it in drive and the transmission sounded like it wanted to slip. I put it back in park and the transmission would not engage. I then killed the truck, re-cranked it, and it drove fine for awhile and started doing it again,
I kill the truck, re-crank it, and we go down the road.
