Ford Transmission :: 4r70w - No Forward Gears Only Reverse
Mar 28, 2009
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 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,.

The truck is a 2002 f150 4x4 5.4l... I was driving down the free way last night in 2wd doing about 90kpm when there was a loud bang like a ran over something. Speedo went to zero and abs light came on. Pulled over and shut it down. Crawled underneath to check so damage and couldn't see anything. Stared it back up put it in drive and it just revs. No forward gears or reverse. Fluid level is good, bright pink. Dropped the transmission pan, pan is clean and magnet has next to nothing on it.

I recently bought a decent looking 1999 f250 4x4 5.4 auto. It has no forward gears and will only move in reverse. I topped off the fluids and have found no leaks so far the cooler lines are crusty but dry. I am gonna need to swap this thing out or do some more trouble shooting if there may be a non rebuild issue to solve.

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.

The other day I was leaving my house. I started the car and heard a quick, loud chirp. That was the only noise it made so I continued to leave. I rolled out of my driveway and proceeded to put it in drive and found myself rolling backwards. I tried every forward shift, kicked on the 4x4 and continued to roll backwards. I thought reverse worked but found that it wasn't engaging either. My question: is there anything I can look at before resorting to taking it to the tranny shop? I'm in school for automotive and am confident in my abilities to test solenoids and maybe even dropping the valve body to check that. Other than that, I lack the skill to pull the tranny myself and work on it.

My 1999 7.3l Disel 4x4 transmission quit on me the other day. No forward or reverse. Got towed to my regular repair shop, and they are treating the transmission as a black box and recommending total replacement. The diagnostics they performed were to make sure it was shifting, and that indeed it wasn't going forward or reverse. They drained the fluid and said "it's pitch black" and said it had to be completely replaced.
Fluid level was OK, and it wasn't hot. I was driving along, and merging onto the highway. It downshifted, shuddred, and nadda. Free rev. I coasted to the next exit and into a parking lot. Verified that it was shifting, checked Rev and all forwards. It wouldn't shift into 4W, and 1-2 also wouldn't move.
I'm trying to figure out what might have happened... and if it's worth trying to have the truck towed to a transmission shop and have them diagnose and rebuild, vs just getting a remanufactured transmission. None of the local wreckers have any used transmissions, and the cost between a reman and a used is pretty negligible...
Not sure what the symptoms points to for exact failure mode, be it the torque converter, pump, input shaft, etc... I've never had an automatic transmission apart before, but built plenty of motors and am a machinist by trade. My preference is to try and root cause the failure...

My '87 Chevy S-10 transmission slips like mad in forward gears and I can't go everywhere in reverse. The truck is gaaged in southern Virginia about 60 miles from my home and is used on some country property. The local transmission shop wants $1600 to rebuild the trans. He says he used sturdier parts than the replacement GM parts. I'd like to fix the truck because it comes in handy and was my dad's old mode of transportation around the Va. countryside, so it has sentimental value.

I'm having trouble with the automatic transmission in my 04' Elantra, it acted like the speed sensor was failing, but later the same day it lost all gears, forward and reverse. after turning the car off and sitting a while I started it back up and had gears again, but the trany is making noise. Fluid level is ok.

I recently bought a 2001 Sante Fe 4X4, (my first Hyundai), that has transmission issues. It has about 135,000 miles on it. It will start easily, and go into Reverse just fine, but would not move in any forward gears. It would occasionally shudder a bit when put in 'drive', but only move forward a few inches. Recently, my mechanic backed it around, then decided to try it in forward again. This time it went forward a couple hundred feet, then quit moving forward. Do I need a new transmission, and if so, what vehicles use this same transmission? Or is there a sensor or valve that could be defective?

I don't know if this all started right after I got back from towing a 3500# lathe + 2000# trailer back from Texas a couple weeks ago or if there might have been some slight symptoms before. I do know that this really got bad a couple days ago and I haven't driven the truck since then.
So, here's what is happening. I noticed a few days before that when I would back out of a parking space, the truck didn't seem to go right into reverse. It was as if it was in neutral, but as I was reaching to jiggle the gearshift lever, it would engage and I could back out just fine. All forward gears, and shifting, have been fine all along, including lockup. I kind of wondered if the shift linkage had somehow moved and was on the edge of being in the right spot, so I was going to have a look at it one evening soon. Then a couple days ago, I went to back out of a parking spot at work and it wouldn't go anywhere.
Just acted like it was in neutral. Put it in drive and it engaged just fine, then back to reverse and nothing for a few moments before it finally engaged. Then, as I was backing up, it acted like you might expect a limited slip that was not slipping to behave. But, that was right before I put it in drive and went home. After I got home, I tried it out some more and found that in reverse, it just wouldn't go anywhere unless the truck rolled a little bit. I don't know if the rolling really had anything to do with it or not, but the driveway is on a slight incline, so it happened, and then the transmission would engage. But, when it did start to back up, even straight, at first it acted like it was under a load, then when it started to move, it bucked really badly. Put it back in drive and all seems fine.
There are no codes set. Trans fluid is full, and doesn't smell or look bad. I've searched for reverse shudder, and other stuff, and there are threads about the TC, about no reverse at all, and a bunch of other stuff, but nothing like this that I found.

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 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.

My low miles (under 50k) 1999 Ranger has a 5-speed manual transmission. One morning, I could not move it. The shift lever shifted, but the gears were locked. No forward, no reverse, and it wouldn't roll in neutral. Eventually, I popped the clutch, and, with a loud BANG! restored itself.
Background: I had rolled the car up tot the curbing in my driveway, so the wheels touched, then shut it off (in gear) and finally set the emergency brake. I'm guessing that this caught the gears in a way that caused the problem.
Yes, it's running just fine now. What happened?

Had tranny fluid and filter replaced a couple months ago. It's in a 35 foot motorhome (F53 chassis). The motorhome is within it's GCWR. Climbing a 6% grade at 3,500 rpm, little more than half throttle, like all the other climbs. 80 degrees out. Engine temp was on the letter "R" on the word "NORMAL". All of a sudden my engine redlines as if it popped into neutral. I let off, put it into neutral, and try "D" again. Nothing.
At this point it's uphill so it's naturally slowing down and I try "2". Nothing. Even slower and I try "1". Nothing. Pulling over blocking the right lane on a blind curve on a grade is scary. Had pylon cones out, waving traffic to warn them down a ways, etc.
No fluid on the ground, no slipping prior to this. I have reverse. I see no obvious linkage or electrical/wire issues underneath (from road debris, etc). It's at a shop but I want to know all I can so if they come back with something outrageous I can make a decision. I never pulled the stick, as I was coordinating traffic, highway patrol, a tow truck, etc.

I have a F150, 2nd 4.6, 122,000 miles. No forward gears. When put in drive, you can feel it trying to engage, but doesn't engage completely. Reverse is a solid engagement. Replaced filter and fluid, same issue.

2003 Explorer with a slipping transmission...codes are P0731, P0732, P0733... Just had a new solenoid pack installed last week when O/D light came on and truck was clunking into reverse. Now, after new pack was installed the forward gears are slipping all over the place!

I am looking at buying a 91 f250 4x4 with a 5.0 and an e4od. When I start the truck I can feel It roll forward A little bit. I can put the trans In od or nuetral and It will drive and shift normally thru all 4 gears, no slipping and no noise no vibration, It shifts and acts perfectly normal. 1st and 2nd work fine as well. When I put it in reverse It rolls forward slightly then drops Into reverse, it will not actually back up, you can rev the engine to stall speed but no higher. Sometimes in park If you rev the engine It will actually over come the parking pawl and roll forward.
Also when In park I can rev the engine to stall speed only. It only starts in p or n, and the reverse lights come on in R so Im assuming the mlps is adjusted properly and the manual protion is adjusted properly. I pulled codes and had 3 in total, ect shorted, egr flow insufficient, and 1 code for torque convertor clutch solenoid I believe It was 632. Im assuming the reving up to stall speed Is related to the tc code. The fluid level Is fine but is a little dark In color, I tried doing a search with no luck ..

I have a 1999 F-250 4X4 7.3 lit Diesel engine. My problem is my transmission will go into reverse great no problem but it won't go forward. I have no problem rebuilding the transmission if that's what it needs, I just want to make sure there isn't a electrical issue from the PCM first?

2006 f150 4x4 4R75E trans slipping in forward gears, reverse is ok. I dropped pan and it was clean. I dropped valve body and found OD servo shaft clip broken, the large snapring was I fine and in place. It allowed the inner shaft to float up and down. Would this cause my forward gears to slip or do I have a bigger problem?

The 91 bonneville stopped having forward gears but was drove back in reverse about 4 miles, reverse appears to work fine does this thing need new transmission or is there an easier fix...
