I know I am new here but i know how forums work i have been a member of GAGT and newcelica for about 2 years. So please no nubbie pun.
I just purchased a 2006 Pontiac Grand Prix base model. It has about 120k miles on it and has a very strange transmission problem. It will shift smooth and comfortable and never slip or shift hard. But if you get on it hard it will shift from 1st to 2nd as it is supposed to but then will not shift to any other gear until you let off the throttle then it will shift hard into gear and you can continue on. What may be causing this? NO SES lights.
I was going to drop the pan and check for metal shavings and if none are present change the fluid and filter. Good idea or bad?
Thank you to anyone that may be able to help.
