C4 tranny cooler is not working

[juiceman]

wow, the advice given is crazy. first, you can not install a cooler wrong. it doesnt have directional flow, does not matter what way it faces, and air does not get trapped in it. next, never run you car and use the tranny to pump out the fluid. whether or not its in gear it still turns the internals and since you have a good tranny you dont want to stress the bearings inside. do you start you motor with no oil in it? a tranny should never get to 300 deg. if it does and it does it consistently say good bye. do like i said and dont use the radiator internal cooler. although im not A big fan of tci, im sure if you got the right gvw. youll be ok. if you think that tranny gets hot from just driving wait till you do a burnout and stall it up at the line. like dynamic said, keep it at around 200 deg. trannies are funny, they, like motors, need to be warmed up to perform well but when too hot will break.
