A/T 4speed fails, car wont move until hot.

[fixkick]

well it needs to work cold and hot,
its a hard failure.

the tests will all fail cold.
the stall (after all it dont move so the stall will fail dead hard)
and i bet the line tests fail. cold
im not sure why but finding it will be hard in the car.
and it will get worse, there are like zero symptoms, on trans that get better in time..

my wild guess is booster is not working right cold, the spring is calibrated to 95hp. and your cars weight.
