Tranny Rebuild

I talked to a guy today that builds race trannies locally about rebuilding my tranny. He gave me his suggestions and an approximate price.

Here is what he recommended:

The Beast Shell
Transgo Stage 3 Shiftkit
A kit that he can get to add additional 3-4 clutches
He didn't say anything about it but I am sure he will also use the Corvette servo

I am going to use a TCI SuperStreet Fighter converter 3500 stall

Cost: ~$850 and I am going to take him the converter.

This guy is highly recommended by people that I have talked to and he said that it is rare to find someone that doesn't like the work he did for them.

Let me know what you think

What type of cam? If it's big enough to need that 3500 stall, the stock computer won't be able to control it.

Just from what I've seen in magazines and so forth, only guys with full on race motors have 3000 rpm stalls.

All I'm saying is you definitely dont want too high of a stall cuz it'll actually lose power and get horrible mileage.

do you believe everything you read in magazines? we have several guys around here that are running 3000+ stall speeds in daily drivers. there are actually a few guys that are running 3800 and 4000.

the cam specs are: 296/304, .539/.558, 112 LSA

Your motor peaks its hp at about 4500, so the motor is only going to be locked to the wheels for 1000rpm at most.
I hope you have a low rear end ratio.
Look in summitracing or jegs. They give recommendations as to what your stall speed should be for the type of car you need.

Here is the Breakaway TC for 2200-2600 rpm:

If you have a moderately modified street machine or daily driver that occasionally sees weekend duty at the track, then you need a TCI Breakaway torque converter. Give your car hard wide-open throttle launches, while maintaining good part throttle driving and very efficient highway cruising. With a stall speed of around 2,200 to 2,600 rpm, it's the best all-around torque converter for both the street and strip.

Here is Streetfighter TC for about 3500 stall:
This TCI Street Fighter is engineered for street-driven weekend racers. Gain ultimate street performance with a stall speed range of 3,000 to 3,500 rpm over stock and competition-style launches. This converter is used by some of the fastest street machines the world over, and is the perfect choice to maximize the acceleration and performance of your car.

If you think you have a street-driven weekend racer then go for it. It'll work but you might be revving high all the time to go anywhere.

Personally, I am planning on going with the Breakaway listed above. My motor is a ZZ4 355hp, pretty tame cam, 10.0 compression.
