If I wanted to build a good strip C4, what parts should I use? I have a case fill tranny, built 1972. What rebuild kit should I use? Should I use an aftermarket servo? Kevlar bands? How many clutches? What valve body? What is your recipie for a stout homemade C4 and how much torque will it put up with?------------------

I have a recipe (s), but have long since stopped doing my own transmissions. By the time you buy all the parts,have the machining done there isn't much savings. A couple of hundred dollars at best. You can buy a great race full manual C-4 from JPT for $895.

So whats your recipe? I would like to know what I can do to my C4 to make it better for racing. I know it wouldn't be as good as a JPT tranny, but much better than a stock unit.

Parts list.
D0TE front pump.
V-8 4 clutch direct drum
Kevlar flex band
Steel cage plnetary gear set
Red Raybestos clutches all (blue ones are not worth the money)
Large assortment of select steels
Light duty pressure plate
NEW Bellville spring
High Quality double lip seal kit
C-6 front bushing
And most important, a high quality manual valve body. JPT builds the best one.You will need some select snap rings to retain the clutch packs and the ability to machine new snap ring groves in the high and direct drums.
A deep pan is a good idea also.

Alex, What about the intermediate servo? Which one do you use? Or does JPT make his own servo and cover?------------------
Larry No fast Fords at this time but one fine cruising 96 F350 CC DRW Power Strokin diesel.
And one rusty 64 Fairlane nick-named the Rust Bucket....And sometimes called the Money Pit...

Sorry, missed that one. "C" or "R" with a double lip seal. Both work well. We have found (JPT and me) no benefit using aftermarket servos. JPT discontinued producing his own as the cost did not justify the gain. ------------------

Are there any good books I can get that are going to break down the internals of a C4 so I can learn all the parts? I need to start somewhere...

Kyly, I just sent you an email with a pic attached of the C4. It is an exploded view of the tranny. The email will be about 87k in size.My suggestion is to go to www.bulkparts.com and order one of the C4/C5 manual for about 15.00. They also have rebuild kits with the red clutchs and kolene steels. They use to carry the kevlar relined bands. Alex, Do you feel the flex band is better than the rigid band?

Careful using the Kolene steels. (drilled swiss cheese and coated)
We have found the coating to cause slippage in high RPM applications (7000+). We use them, but sand blast all of the coating off.
For years the hot lick was a rigid birch bark band. It still is in hot street or medium duty race applications. We found that with as hard and fast that we can make the band apply, it actually shocks the drum too hard. The kevlar flex band has just enough of a softer hit to help keep everthing in line. It's nice to have a trans dyno at your disposal to test and try parts.  The real test is going down the track with 500+ HP or more applied. ------------------
