I have to play with the accelerator to get the transmission to move.

What is your question?

For the most part the transmission works good except when the light turns green I have to pump the gas a few times until it goes into gear. Occasionally like 20% of the time it slips a little in passing gear if I accelerate to hard but 80% of the time the passing gear works fine. I am a taxi driver so it is very annoying and embarrassing because I drive a lot. I just had this transmission installed 60 days ago and supposedly it had 75,000 on it out of an old police car. The fluid was very clear when I got it and still is.
