4L60 transmission.
Ok one of these days my transmission is going to give out, I have a hard 2nd gear shift when she is cold. I want to keep my orignal transmission because of VIN numbers, does anybody know what is best to do, SHOULD i have a speed shop rebuild it using 700r4 high performance parts or should I just take it into one of these mom and pop transmission shops and have them rebuild it.

Does anybody know a good speed shop in Houston or Dallas that does transmission work???

 

Here is my basic recipe for a 700/4l60. TransGo Reprogramming kit and the Hi Rev release springs that come with it. TransGo Hi Rev Pump Ring Kit. 4L60E 3-4 pack and Input Sprag Assembly. All Borg Warner frictions. Corvette rear planetary. NEW GM Sun Shell. Minimum endplay settings. Depending on power, 553 Servo or 093 (Vette). .422" PR Boost Valve for small block, .477 for big block or HIGH power small block. .282 Int/Rev Boost Valve. TruCool LPD cooler and bypass the radiator.
The converter choice depends completely on the power band of the engine. Your stall should be at or just below where your engine STARTS to make power and the WOT shift points should be set so that it is completed BEFORE the power starts to fall off (NOT your max RPM). A top quality converter supplier is Continental: The number for Continental Converters in Inglewood Ca. is 1-310-674-1072

 

Transfixleo is a good trans guy. What you need to do is ask the question to a few local shops and see if you get a response like leo's. They should be knowledgable and complete with their specific building tecniques. If you don't like what you hear move to the next shop. In my area I find the small shops more knowledgable than the larger chain stores like aamco.
Just educated yourself as to what you want and work with them to get it done to your satisfaction.
