Sup guys. Got in my car today and after driving about 10min. Heard a slight whining noise. With having these old cars my ears have gotten very sensitive to any little noise. But right after I heard the whine it started slipping I was only going about 40 at the time and then it got to where it didn't want change at all so I let the car coast until it was barely moving and then I had to get down on the gas and then it finally kicked in and got up enough speed to get it home. I checked the hoses and they are still on it. What do u guys think this is? I hope I don't need a new tranny.
