Problem with my transmission.
 

Hey guys I'm new here and I own a 1995 lexus Sc400. The current problem I have with it is that when the car is cold I shift the car into any car and its all fine but after about 1 min. it will start to slip and then won't shift at all, no matter what gear you put it into it will stay like if it was in neutral, but then you turn the car of wait about 5 min. and it will shift perfectly again.
