If I start driving at normal speeds then floor the car the car doesn't down shift. I adjusted the tv cable. Should I replace the damn thing?? Time for rebuild??I need help.

 

If you just want to solve this problem, I would install the Trans-Go Shift kit (Green & White box), this will solve the sicking TV valve and will make the TV calbe sensitive to adjustments as to down shifting & upshifting. This kit can be easily modified to HD specs. Along with this if you want it to be HD would be the larger boost valves & Corvette servo. Let me know if I can be of help?

 

What are HD specs?? And what does the TV cable do? I see people mention it from time to time, but I have no idea what it does, or lack there of. Is there something wrong with the original setup of it or something? Or does it just brake a lot?
