I have never rebuilt an auto trans before, but I'm the kind of guy that likes to do everything myself. I couldn't afford to buy a full boogy racing trans, so I thought ,what the heck? I did a lot of studying and researching and did it myself. Today the weather was great so I took it out and tried it with my fingers crossed. It seems to work great.  It's a case fill C4 that I rollerized. It has a full manual valve body, racing clutches and kevlar band and a JPT 4900 converter. Wow, that second gear hits hard. It's WAY better than the manual C6 that it replaced. The only thing I don't have is a trans break. I can't quite afford that, yet.
I can't wait until the racing season starts. I'm looking to drop 2-3 tenths in ET. I also hope the trans doesn't let me down. It's really an experiment for me, but I don't think I'll ever hire a rebuild again. It ain't that bad.  ------------------

My c4 hits second gear a ton harder than my race c6 ever did. After watching KK's brother Dave pull my c4 apart several times, I dont think there's that much to them if you have the right parts to put back in. I have a c4 in storage here that needs gone thru (high gear wont work). I think I'm going to try and fix it myself. Yep, I wouldnt be suprised to see a 3 tenths improvement in your ET.

Typically there is a .020 decrease in ET from the best C-6 to a C-4.
This excludes any Mopig 904 parts equipped C-6's. ------------------

Hey, Kid. You probably have an advantage over me, since you have seen inside one with KK's brother. I was always afraid of them. There was some kind of voodoo magic inside of them.  That's why I have never messed with one before. I always hired out the rebuilds. Money is tight this year, so, you gotta do what you gotta do. I'm not afraid anymore. The fact that I'm a machinist helps.
As for dropping ET. I'll take all I can get. My best ET last season was 11.29 in the spring, but the average settled in at mid 11 in the heat of summer. I'm still aiming for 10s. ------------------

I thought the same thing till he opened mine up in front of me. I always used to pay someone to do mine also. Now I think I want to take a crack at fixing the one I have here for my '70.
My c6 must not have been very efficient. I picked up almost 3 tenths when I switched from it to my c4.

Kid and others.....You will need two tools to work on the C4 that usually aren't part of everyone's tool box. The first one you will need to buy is horseshoe snap ring pliers and the second one you can make if you have or acess to a welder. You will need about 12" piece of 1/2" threaded rod or an old spare tire tie down bolt and a piece of flat steel 1/4" thick by 2" wide. You will need to make a U shaped by cutting the flat steel into 3 pieces. Two are about 2" long and the other long enough to span the drum to remove the clip and spring. U shape the two short pieces and welt them to the long pice and drill a 1/2" hole in it. Then use you vise to remove the clip and spring and to re-install it.

Most tool trucks sell the clutch spring compressing tools cheaply also (except snap off). ------------------
