i just bough a 95 trans am lt1 with a 4l60e transmission.it seems at wot it doesnt want to shift,if i let out of it it will shift .is there a adjustment cable or is this a computer reprogram job.it shift fine under normal driving conitions.this is an all stock car. the transmission was rebuild last summer.any help thanks

 

oh yeah ...it just had a rear end put in it right before i bought it .it had 2.73s now its 3.08s.no speedo adjustment either

 

What is the condition of the fluid? The TV cable is not used on 4L60E's. Except for this problem, does it shift ok otherwise? If it does, you could add the Corvette servo, this will help the 1-2 & 2-3 shift. Larger boost valve would help too, and the "modified" Performance Trans-Go Shift kit. It depends on what you want to do. Let me know?

 

Hey Pro Built Automatics you are from calimesa. I am from Cherry Valley. Do you know of anywhere good local that could put new gears in for me? Thanks for your help.

 

like i said under normal driving conditions it ****s fine,firm shifts no slipage.the fluid is still red doesnt smell burnt.what will the corvette severo do? will it lower the wot shifts for 1-2 2-3.the way it is now i dont think it will shift went i put it to the floor. i wouldnt mind putting a shift kit in it but whats the good if it wont shift

 

For rear end work, call Performance Motorsports, ask for Jim Cook, they are in Ontario off the 60 Freeway at the Vineyard offramp. 909 9237707 It has been awhile since I have talked to him, but he did excellent work for years at a reasonable price.

 

what color and year car do you have Pro Built Automatics? I have probably seen you around.
