I was thinking about installing a Banks Transcommand or a shift kit and need to know which transmission I have.

I have a 1995 F150 with 302ci engine. The code in the door jam is "U"
Any help would be greatly appreciated!

 

4R70W

 

Thanks,
Whats the difference in that and the E40D?

 

Two completely different boxes. The 4R70W is the AOD-E with wide ratio gears. It is based on the old FMX tranny with an OD grafted on. The E4OD is based on the C6 with an OD added. The E4OD has a higher torque capacity.

 

Thanks alot! Its been shuddering pretty bad here recently. Im not sure if its the torque converter or not. Its been doing it since 50K but gradually has gotten worse. It only does it in 3rd and OD, and I can turn my overdrive off and it continues to do it, like it doesn’t want to shift down. On the other hand I can be accelerating on a smooth flat road and when going into top gear it will also do it. Both ways I can push the accelerator down until it drops gears and pick up speed then back off and it changes into gear like it should, just with a hard shudder as it changes.

 

I'd consider buying a rebuilt trans or pulling yours and having it rebuilt before I would spend money on the shift kit or other mods that won't FIX your problem. TransGo shift kit really firms up this trans but I doubt it will fix your symptoms. Contact Larry Church at Blumenthal Manufacturing in OKC, OK and they can sell you a rebuilt trans as cheap as anybody and ship overnight <$100 return freight inluded for core.

Hey Guys, The conveter shudder can be cured by instaling a Gil Younger (Trans-Go) HD shift improver kit (# AODE-SK) It will quicken the shifts and no more shudder, if ya want a firmer shift use part #AODE-HD2.... while you have the pan off its a good idea to replace the TCC solonoid and use nothing but Mercon V trans fluid

 

I was told by the manager at Mr. Transmission that transmission fluid acts as a detergent and if you are already having problems and put in new fluid then it eats away at things and makes it worse in the long run. He recommended a tube of additive and I put it in and so far no more shudder! Probably only a short term fix though.

 

Remember that was the guy at the tranny shop. He makes money off of killing your trans. Just remember that if he is wrong don't ever take it to him to fix because he will gaurantee repeat buisness if you know what I mean....

 

I'm sure Mr. Trans has his reasons but if new fluid "ate" up transmissions, wouldn't new trucks come with old oil? ATF is first a hydraulic medium because auto trans need pressure, second it is a lubricant and third it moves heat. Any liquid could work if it did not boil at the temp involved. The seals/clutches/pump/torque convertor are designed for a particular fluid when new. That is why we have to change fluid. We remove contaminants and make the fluid as close to new as we can. New fluid will not fix a worn transmission but neither will most other things mentioned here. The quick and easy fix is not always the cheapest or most dependable over time. If you don't have long term plans including this truck I will not argue with any methods used. It seems to be working for now. I wouldn't expect miracles though. We'd have to know the exact problem before making conclusions. Sounds like lock up torque convertor problem, not overdrive but I'm no Mr. Transmission.

 

Tim, I thought the same thing when he was telling me that. I have heard that draining all your fluid including your torque converter and refilling with Mercon V will sometimes fix this shudder.

I would do it myself but I’m at school and living in an apartment so I don’t have anywhere to do it. He told me what I said earlier and that he wouldn’t do it, if I wanted that done to take it to jiffy lube. I think he was blowing smoke. I’m going home for thanksgiving and might give the Mercon V a try. I’m trying to get around spending any big money b/c I can barley afford my tuition, rent, bills….
Thanks a lot for all the replies!

 

Dexron III and Mercon V are not interchangeable nor is V an improved version. Some transmissions have to use V. It is just different as Type F is from A. It may have some advantages but your trans wasn't designed for V. If this worked for somebody else, changing oil and sticking with Dexron III probably would've worked as well. Be careful what you do. I can't say it won't work but I wouldn't put 90 wt. in my crankcase. This may not be as drastic but try to find out more and ask why? College isn't about learning all the answers. College teaches you to research and find information, sort through it, throw away the stuff that you don't trust, and make your own conclusions. When I got out 20 years ago, I too was very trusting. I hate being skeptical now but not everyone here including me can be right all the time. Some are qualified Ford technicians and others of us have experience. Some though have just heard or read something that sounded similar and might have fixed someone's truck. They have no idea what makes a truck run nor how to keep it running. Anybody can tear one up. I did see a thread a few days back about switching TC to the new 5 sp version for ~$200. I'll have to look. Ask questions at different shops and make friends with people who work on Fords. Some people will help you and provide accurate information. I have not experienced "shudder" with either of Ford's gas version transmissions. I'd try to find out why it does it. I've go a AODE shift kitbut no AODE (4R70W). You drill a new hole (in valve body inside pan) , enlarge another and change springs to stiffer ones in valve body. I'm looking into TransCommand as well but for more control, not to fix anything. Spending a little money several times on useless things is more wasteful than saving up for later. Sometimes I had to ask Dad for help. Bottom line I hate walking (or paying idiots to work on my truck).
