Hey everyone! I am hoping that somebody can give me some insight into this issue.

I have a 2007 JKU (automatic). It is shifting hard from 1st to 2nd gear. When it shifts it feels like there is a delay (power loss), and a quick jerk. Almost like if you are driving a manual and you shift but you are slow about it type jerk.

I don't hear any strange noises while it shift. The rest of the upshifting and downshifting is fine. Torque convertor?

 

It may be the start to something bad, I've been through 2, yes 2 transmissions so far. Can't recall how many miles are on it. I'll have to look. But when both of mine failed they slipped and then slammed into gear. First time the whole trans was fubar. The second, the pump failed taking out the converter. Check your fluid, and hope you have lifetime power train warranty! I did. 100 bucks = new trans. X 2! Lol

 

when was the last time you had your trans fluid changed? sounds like it's in the early slipping stages which will eventually just fail...
