I have a 88 GT Automatic 5.0 and the transmission in it is totally shot to death. I need a new transmission to fit my needs and I was looking at the AOD to C4 conversion kit fromPerformance Automatic. I was just wondering if anyone here has had any experience with the C4 and what did you thought about them if you did. It sounds great but I havent spoken to anybody whos had personal experience with them. Here is a list of what the kit comes with. If anyone would have any suggestions on something that the kit does not include that I might need, please let me know. Thank You.

It's a good swap for a drag-only car. I can't imagine doing that on a street driven car though. It's tough as heck, but it'd just kill any highway driving. I have a C4 in my 66, and it is a good transmission. It isn't crazy built like the one you are looking at, so I'm sure it is a different animal. Us classic folks have an expression: "You know your C4 is working correctly because it is leaking". I'm sure it is possible to have a good running C4 that doesn't leak, but I haven't run into one.

 

I never had a leak in any of my C4s but i agree they are great transmissions and can take a pounding.

 

PLEASE PEOPLE I NEED SOME HELP :bang: :bang: :bang:

 

are you not recommending it as an everyday driver because it does not have an overdrive?

 

I can't really help you out, but I got you moved to a forum that may be able to offer a bit more help.

 

ok thanks alot JeffreyDJ

 

Yeah that would be the only reason. Have had several cars with C4s in them though none built like the one your putting together. No over drive is painful for you if your running a performance gear ratio.
