what is the averge cost to rebuild a c4 for a |6 would it be the same amount to go to a 5 speed which is what i want to do but funds are really limited now. and the c4 that came with the car that i thought was good is not good.
You can rebuild the c-4 for $150 or less. It is not that hard to do if you just a little handy. A shift kit and extra clutches could be added for another $75 or so but if you do not plan on swapping out the I6 it would not make much since. You may have some trouble with the removal of the reverse drum, but that is about it. Once you "crack" the case you will find the auto transmission mystery is not that big of a deal. The C-4 was our first auto tranny rebuild. We contacted a local tranny shop and made arrangements to be able to deliver our C-4 in pieces if we got stuck. We never had to use that insurance plan.
Five speed swap will certainly cost you more than the C-4 redo and not sure the performance delta would be noticed with the I6.
The last time I paid someone to overhaul my C4 (advertised price of $375 in the paper) he wound up adding a bunch of parts that I didnt want or need and tried to stiff me with the bill. After some calls to the BBB he eventually backed off and we settled for around $450. However that was over 10 years ago.
Just last year I had a C4 completely overhauled for $1200 at one of your nationaly recognized places. And no it wasn't the first one that you come to in the phone book
For what its worth, about a year ago I purchased a rebuilt C4 from auto zone for right about $400. Its a special order item, but it took less than a week to arrive. 12 month, 12k mile warranty (or something like that). The only quirk was having to swap in my linkage before installation. I've had the car on the road for 6 months and so far, the unit is working fine.
i live in the bay area. i ended up paying about 1100 for my C4 rebuild. but, it was pretty shot, it needed everything replaced. all the bands and clutches were toasted, my front pump was toasted. you name it, i broke it lol.
this price also included the fact that i didnt pull the tranny and drop it off, i didnt have time bc of work. i just dropped the hobbled car off and said you do it this time.
about two yrs later its still doing great , and it chirps second gear once in a while too, without a shift kit. im thinking about going back and having a trans stage 2 put in it for kicks.
