I was told that there is another tranny, maybe better, that i could swap with my e40d, if it turns out that it is no good, and not my rear diff.... If this is the case...

Do they make a stronger or better one, that will bolt on to a 1990 f150 4x4 5.0 ?

I see some people saying they have "c-6" and not e40d tranny's, have these people swapped with those better ones ?

 

The C-6 is a three speed automatic from the 60s. improved over the years yes, but still a three speed. Its beefy, and made for towing. The E4OD is a four speed automatic electric transmission, where you can electronically switch the OD (over drive) off on the dash. That was the biggest baddest automatic offered in the F150 for our years, if I am wrong somebody correct me.

 

As far as automatics, these trucks came with C4, C5, C6, AOD, and E4OD. The E4OD is the only one electronically controlled and if you swap it out with something else the computer will miss it. What I mean is the computer will see it's not getting any readings from it and light the check engine light, or at least store transmission codes. Changing to one of the other trannys will be a bit of work, needing all or some of the following: driveshaft, crossmember, kickdown cable or rod and attaching mechanisms, computer if you don't want the check engine light problem, and anything else I'm forgetting.

 

You didnt forget anything Sean.

 

So much for that idea, if there was a direct bolt on swap i would do it... but not if anything else is involved... Pray to buda tomorrow its just my rear diff thats broke.

 

What about the 4R70W I love mine.

 

I dont think that is a direct bolt up.

 

Hmm ok im not sure on that I thought it was.

Now I do know the 4R100 is a beefed up E4OD

 

you can put all the clutches from a f-250 or 350 diesel into the E4OD without any problems, I have heard of people doing this with the 5.8 that were built. Reading up on it the 150 uses larger metal plates and fewer clutch disks in them.

 

i have a 1993 4x4 with the 5.8L and i want to put a 5 speed in it does any one know of a tranny that wont be to hard to swap in i want to keep my stock transfer case and drive shaft. im 18 years old and i rebuilt this truck then i was 16 and the stock tranny went out i dont want to get rid of the truck since ive put so much time and effort in to it so figured while i was ripping it out anyway id have some fun and throw a manuel in it if any one can help id apprciate it thanks
