I hopr this post is in the right place. Still learning to navigate around here. Hope someone can shed some light. 2003 gpgt, every once in a while when i push the gas it moves slowly then suddenly engages like its slipping. It has 140,000 kms on it and i just replaced the cat cause it eas plugged. Does this mean my transmision is slipping. I am not a car guy so i have no clue. Anyones feed back would be great. Also any ideas on how to correct it(without a new tranny lol) !!!
