help ! high rpm hesitation
i changed my tranny fluid today and decided to test out the perfomance. i had my nose in front of him the whole way through first, but when my rpm got around to 4400-4500 it just hung out up there, with no power going to the wheels, like it disengadeged and didnt know which gear to go into. im guessing about every 2 of 3 times i floor it like this (i really only had it about 80% to the floor) it hesitates like this in the high rpm. all the other times its a nice firm shift into 2nd, like one would expect.
getting into more detail. im suspecting through observation, that its more likely to do a desireable shift if the car is:
1. going up a hill
2. full of people
3. im towing a load
basically if the engine has a real load on it. but the other times it hesitates when its strait open road.
does anyone else experience this phenomena?
