one other thing to note on this car is that in the summer the transmission has a problem with short shifting when it's hot outside but, not always, it's really unpredictable. I have another computer I can install to see if this cures all my ills but, I cannot find the unit to replace it. anyone know where it is on the 2000 GP se 3.1? this transmission has been professionally rebuilt and has been inspected several times and there is absolutely nothing wrong with it. also what can be done about the evap canister if it is saturated? can i just replace the pressure regulator?
