hey people, I'm looking for some help, I've had my baby in the shop for 2 weeks an she still acting funny, the problem is my tranny shifts funny, rev high between the gears and shifts like a stright drive I can feel it jerk when it shifts, open to any and all that can be said on this matter, lookin to see if anyone has been throught this or and thing like this thanks.

 

Welcome to the forums, just a couple of questions? What's the year and what engine?

 

The high rev tells me possible slippage, the hard shift can mean increased line pressure (lots of tuners increase the pressure on purpose to firm up shifts)

 

its a 2002 1500 wit the 5.9
