700r4 problems shifting after vette servo install
Hey guys I just installed a vette servo in my 91 Camaro the other day and when I drove it I was almost over revving to shift then it went straight to 3rd when it did shift.
Could that be a leak on the servo or? I don't know I'm dumbfounded. Fluid is full

Could be a bad seal but did you move the T/V cable when dropping the trans?

I don't think so. And the car has 120k and was originally a manual so it can't be that old
