Have a 1993 F150, 5.0L, V8, 2 Wheel drive. When driving and the transmission wants to shift from 2nd gear to 3rd gear, it shifts hard into 3rd. I hear that there a few problems that can cause this. Would a dirty filter and old Tranny fluid cause this?


thanks

Possibly needs a flush or pan drop/filter, Go that path first then see what happens.

 

Always a good place to start How old is the fluid and filter?

If your fluid is brown, it would probably be doing it all the time. Sounds like something else, but if it needs it, do it.

 

I think the fluid is probably as old as the truck. I just picked it up recently. The guy said it could the electronic sensor, but I was reading that old fluid could cause this. Guess my best bet is to change the filter and fluid and see what happens.

Where can I find information on the truck that tells me which transmission I have. This way I order the right gasket and filter.


Thanks

Check your door sticker:



I know its kind of hard to read, but I can read it so ask me if you need anything clarified.

Code G. Is that "Automatic - C6"??
Code U. Is that "Automatic - 4R70W"??

Thanks for your help Chris.

Right on the money. You're welcome.

 

Yeah I'm going to give you a little warning so you don't get disappointed later. This problem will most likely not be solved with a fluid and filter change like rattosh said. BUT! If the fluid and filter are original to the truck then they definitely need to be changed anyway. Just don't use anything expensive like Amsoil or Royal Purple because from the sounds of it you might end up needing to drain it all out pretty soon But who knows, it could fix your problem and you'll be done with it.

We had a ford van at work doing this same thing (e4od, shifting hard from 2nd to the 3rd) and when we sent it over to the fleet services facility they inspected it and ended up replacing the transmission. Didn't give us any details as to what was wrong but apparently it wasn't worth servicing...

-Chris

 

I believe it is an e4od and sounds exactly like the problem that you had with your van. I am not looking forward to replacing the transmission. NOT at all.

 

Well get some new fluid and a filter in her and see what happens. Even if the tranny does need to be replaced, you might be able to bandaid the problem enough to squeeze another 20k miles out of it (who knows?). The problem with our van didn't seem to be self-destructive to the vehicle, it was just irritating. If your is the same thing, and you could get it to a tolerable amount of kicking between 2nd and 3rd, then you won't need to go running to buy a new tranny right away.

Oh and make sure to use Mercon/Dextron III.

How many miles on the truck/transmission?

-Chris

 

Thanks Chris.

Tranny has 170,000 miles on it.

 

Yeah, to be honest, 170k miles on a 93 E4OD is already pushin' it. You're lucky you got that much life out of her. Especially without ever changing the fluid, heh. Good luck man.

-Chris

 

Hey Chris. Just went to verify what type my tranny was. Come to find out it is a "T". I don't see a "T" on your list.

Any ideas?


Thanks

 

Hmm. I believe the T code for transmission denotes an automatic 4-speed that they put in Rangers... Interesting that its on your tag... Are you sure that you are looking in the right place? It would be under the heading TRANS or TR most likely.
