what gear are you in at 50-55 when you start slowing down. If you are right at a shift point, and you let off the gas before it shifts to the higher gear, it will slow faster. As far as the spike goes, it may be getting hung up at the next point. Is your fluid at the proper level?

It's after the shift point, not before... Fluid was first thing I checked.

hello

who knows trucks???????

I need a chat room for trucks???????

Get a new jeep!

Try a trans flush if you haven't had one in the last year and a half or so. You put a lot of miles on it. If the flush doesn't correct the problem, you may need service on the trans. I think the car is still worth money -if you've kept it in good shape.

got trany for sell if u want it cheap
