Hello ford heads!
I have a f150 4.9. 3 speed od trans. 1994
Afreind of mine told me there is a way to bolt a c-6 trans to a 4.9 if i use a 70's or 80'sa model trans.
I dont know what to look for.
Also he said to use a 5 bolt.
I guess im looking for clarification on this issue.
Like what to use and if there is any mods i need to know about.
I need to increase the pulling power of my truck.
thx in advance for your help in this matter. Greg

The C6 was used for many years in both trucks and cars. If there is a difference in the bolt patterns then I would think it would have to be in the engine it mated to. Ford made a few I6 engines and the C6 mated to a few including the 250 and 300.

The C6 was a good transmission and was replaced by the E4OD which should bolt right up to your truck and gives a better gear range over the C6 since it is a 4 speed versus 3 in the C6.
Thx, mrmac
I think i have the e40d in my truck now. Im just concerned about the E40D holding up under
alot of pulling and hauling.
My plan is to change the rear suspension to a 3/4 ton.
In your opinion will the e40d hold up?
The E4OD was a beefed up version of the C6 which also added the fourth gear. I don't really think that moving to an earlier version would help too much. My '92 F-150 was a 4.9 with the AOD auto and I was able to tow my old ski boat without any issues.
