A 1990 700R4 with a B&M stage 2 shift kit and a corvette servo. All the inside is stock and has never been messed with. Oh and the tranny had 175,000 when the shift kit was installed and 204,000 when the servo was installed. I am going to the track tomorrow and I am wondering if I should be worried that it will break, cause it's been running great so far. What do you guys think?

 

if it shifts hard and crisp,it should hold up to 400 ft lbs any more than that,could go out any time, ,some last longer than others
