Ok so i need some help when i first start to drive the car the transmission feels like it slips out of geer and back in .... is hard to explain how it feels but it only does this until its warmed up. for the most part it is from when i stop and then start to move, it dosent really ever do it when its already moving. any one have an idea what the problem is?

 

okay so i have a lengthly post on here somewhere describing how to "fix" a common 4t65E issue. i won't go trough it all again but if you find it and do what the post says it will instruct you to email me and i will send you picture diagrams of what i'm talking about.

but a summary is drop the trans pan secure steel tubes inside it increases trans fluid pressure yadda yadda. if it doesn't help it still needs doing because it will increase the longevity of the trans.
