I have a 2000 pontiac grand am with the 3.4L and auto tranny.
I thought a while ago that people had told me that the engine must be running to check the fluid level in this tranny.
Checking my Haynes manual it says that the vehicle must be run to op temp and cycle the shifter through the gears ending in park and then shut the engine off and check the level.
I can't remember but I thought I did that last time and about a quart and a half came spilling out.
Could the Haynes procedure be wrong?
Thanks
Rico then shut the engine off
