Ford Transmission :: Reverse Shift Bogging Down The Engine
Mar 3, 2014
I've got a 1994 F-150 with the 4.9 straight six. The transmission is the E40D.
In drive, it shifts silky smooth. In reverse, it acts like it's bogging down the engine.
I only recently got the truck. It's had a fluid and filter change, and is full on the stick when hot.
I didn't notice this problem until I replaced the engine thermostat. It was stuck open, so I replaced it with a 195 degree Stant unit.
Should I let the engine control computer re-learn this engine? I've fixed bad vacuum lines, too.
I've heard tales about the electronic transmissions. This one has 145K on it.

I have a 1993 F150, 302 with E4OD, I've replaced most everything I can think of to address the engine bogging in reverse (TPS, EGR, VSS, replaced the trans filter, tune-up and MLPS). It does not bog every time and seems to do it more when the engine is warm.
I pulled the ECU and opened it up. There was nothing obvious inside that looked burned, damaged, etc. Since it is almost 20 years old and the truck has 197K miles, should I go ahead and replace the ECU as well??

I just recently bought a 95 F150 with a 351. The truck has high mileage, about 190k, and I am not sure how long the transmission has left. It rides smooth down the road, but when I put the truck into reverse it hesitates for a moment then makes a loud clunking sound(as if a door is being slammed) and then jerks into gear. The reverse works great at the moment though. Should I be worried, is there anything I can do to fix this?

I have a 1970 f250 with a factory 390 (vin verified) and a C6, I believe the transmission was rebuilt but have no way to verify. It works fine while cold and mildly warm. Once heat soaked it is very slow to shift (going from neutral to reverse can take almost 30 sec) and leaks profusely from the front. I can not tell exactly where the leak is. Could this be a case of just having too much fluid or is there a more serious concern? The dipstick does read high but level ground in my area is hard to come by so the accuracy can be questioned. If it does have to much fluid, do I just drain the pan, re-install and let it run till hot and replace fluid as needed or should I drain and replace with 3 qrts prior to starting?

I have a 95 F250 with 7.5 and E4OD. I was towing my Jeep and trailer out for the weekend a few months back (its been parked since) and heard some noise coming from the trailer. So at a stop light I put it in park with the engine running for a second, went to put it back into drive and it hasn't gone back into drive since. Reverse works perfectly. Fortunately I was able to back up onto the center divide, unload my Jeep and back the truck onto the trailer and tow home with my buddies Chevy. Anyways, its been dead since. Where I can start to look? None of the forward gears work at all.

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.

2002 LS V8 162K Miles. Its been sitting in the garage for 10 days. ...went on vacation. Started her up and let it idle down. Shifted to reverse and transmission shift error displayed. Went back to P. Waited a minute. Shifted again and she was hard jumping into the gears. The error went away. Drove it around and it seems to shift fine. Opinions?

I have a 08 Subaru 2.5i Impreza and until now I thought this was a fluke but it is happening more frequently this week.When I park my car I engage the the parking brake and put the shifter into first gear, turn the car off ... etc... When I go back to the car I depress the clutch, start the car, apply the brake and disengage the parking brake. I then proceed to shift to reverse to back out of my parking spot, here is where the problem lays. More often then not the car shifts to reverse and I am on my way but every so often the shifter refuses to go into reverse until I release and depress the clutch pedal. After that it drops into reverse and away I go.

My son has a 1987 Chrysler 5th Ave. The transmission (auto) does not want to shift in reverse. It does go in neutral and forward. And it drives well forward. How to fix this?

Bought a 2003 golf gti 1.8t as kind of a project. Car had no interior no exhaust and some shifting issues. To fix the shifting issues rather than replacing solenoids I just got a rebuilt valve body. After installation the car still doesn't shift from 1st to second properly and now I don't have reverse. (It's an 09a transmission)

I am not sure if it's my imagination or not, but my car seems to be running differently lately.
When the car shifts into 4th the Rpms seem to drop kind of and the car seems like it is bogging down. Not extreme, but I don't remember this when I first got it. It's like I really have to accelerate when it shifts into 4th or I cannot pick any speed up.
Is it because the motor is now broken in? It has right at 8,000 miles now. It's due for an oil change, but I wouldn't think that would have anything to do with it !

I have a 97 jetta trek that is having problems. Grinding noises from transfer , no reverse, hard to shift, loud winding noise. I think it's may be the trough out baring thing from what I'm reading.

When backing up in reverse I come to a stop and shift into drive. About 60% of the time it slams into gear (Drive). It feels as if someone rearended me. It's a 2012 Chrysler Town and Country with 40K miles. 2 dealers worked on it, reprogramed the computer and replaced 2 seloniods and the problem is still there. What is wrong but said thats typical on that 6 speed. What to do next?

Ok so about a week ago I was driving my 02 impala and I heard a loud noise while driving at 30 mph and it lasted till about 50mph. well I had my dad take it down the road while I was at work about 5 days later to hear what the noise was wondering if it might have been a hub. Well I call him an hour later cause he ain't back he says he's at the gas station and it won't reverse. Well apparently the noise was just my transmission being loud cause it was taking a while to shift. I've never had a problem with my tranny but some leakage which I think is just the gasket I just know that theres tranny fluid under my pan on one side. So I went to auto zone and they got a code for p1811. So I'm wondering if it just needs a filter and gasket change or is my tranny gone. It still shifts into gears just takes longer in 2nd and I can't drive in reverse at all?

I bought a brand new 2016 Camry LE. Sometimes when car sits for a while, and I shift from P to R, there is a clunking noise with foot on the brake. I tried with the parking break engage and it still does it.

So last weekend I installed a transgo kit for my 4R100 transmission in my 2000 F250 diesel. I didn't really care about getting a shift kit, but I had problems with delayed shifts and figured the accumulator springs had broken. It turns out that was correct, the 2nd gear spring came out in 8 pieces.
Anyway, the transmission shifts great now, but when I put it in reverse it the engine jumps up 200 rpm and then it bogs down as it engages reverse forcefully. It also does this while selecting 1st from Park.
From what I'm reading it's the TC not unlocking and/or a fluid pressure/volume issue. I've also read the filter might have fallen off, I had a hell of a time keeping it in place. I've checked the the fluid level and everything is good there. My question is when I drop the pan, aside from the filter, what should I look for?

I have a 05 expedition and when it goes to shift from 2nd to 3rd the engine revs up and shifts hard all other gears shift fine. What can this issue be and is it a easy fix?

I'm a new Ford owner and my 2012 F250 is my first diesel. Recently, my truck has been having a problem with the engine loosing power, bogging down, shaking-pinging, every once in a while, like 1-2 times a week. When it happens, I can barely get the truck to do 50 MPH. It sometimes happens when the "cleaning exhaust filter" message is displayed, but also happens when it's not displayed. I recently read on the internet about HPFD failures.
What may be happening to my truck? Could it need Cetane booster? Also, how about scheduled maintenance. The owners manual (diesel supplement) says to do the maintenance once the message center says to change oil soon. The dealers here in AZ are pretty much saying 5 months or 7,500 miles. On my other trucks (which were gas), I would stick to what the owner manuals said because I thought how could they deny a warranty claim if you're sticking to what the manual says.

My old 97 f-150's 4R70W started slipping.....so I just installed a rebuilt 98 f-150 unit that had about 10,000 miles on it and also has a transgo shift kit. Got it finished today....and.....
I have an check engine light code p0750 "shift solenoid A malfunction"........when leaving from a stop in Drive, the truck starts going in 2nd gear and just skips 1st gear all together. If I manually shift it, then 1st works fine and shifts through all the gears fine.
But in Drive.. it skips 1st. What to do? or what could be the problem? Where is this solenoid? Can I swap the one out of my old tranny into this one without pulling the whole tranny apart? (I don't mind dropping the pan though...) Or could i have a bad connection somewhere maybe?
Also....When the tranny shifts from 2nd to 3rd the rpms jump about 500 rpm before they drop...kind of seems excessive. Could this be caused by the shift solenoid A malfunction?

Recently I have encountered another issue. Truck started up fine, at first stop light and truck was bogging down, RPMs jumping up and down slightly and sounded like it was going to die. Light turned green, gave it gas, no response. Gas pedal was dead. After restarting the truck I was able to give it some gas until I came to the next stop light and this repeated. Eventually a few moments later I got a check engine light. Drove home this way, seemed to be working fine as long as I was actually driving and not stopped.
All the parameters looked ok except for the battery, that jumped up and down in volts as the engine sounded like it was bogging down then eventually died. New batteries put in approx 2 months ago. The check engine light is showing "P0299 turbo/supercharger underboost". I have attached an image of this check engine light according to my monitor.

Here is the case. I drive a 150 mile trip once a week, mostly 60-65 mph highway. Well in the last 3 months it started randomly bogging down slightly with the cruise on. I can be going along and its like a strong gust of wind hits the truck from the front. It will make the engine bog then it like releases or frees up and the truck carries on.
I also noted on my edge evo (not programmed just plugged in for the gauges) that it shows the engine load shoot from about 30% cruising to about 80% when it have its issue then on the sort of POP release the load goes back down to the normal range. The entire bog down only lasts about 3-5 seconds and I can power out of it by pressing the gas. It may happen 15 times on the trip may only happen once or twice...very random...
Things I have tried
Replaced plugs and COPS
Replaced FPDM
Cleaned MAF and TB
Replaced Air Filter
Changed Oil
Fuel Filter changed in November
