Ok I will try that. I just got the software im ordering the cables today. I did lower the rpm to 650, any lower was feeling like it was going to stall, but it didint jump at all today. It could be a coicedence as it doesnt happen everyday, but ever since they changed the carrier bearing the jump has been more violent.
I also cleaned the plugs on the passenger side hopefully it was something that simple.

No ive never let anyone wash my engine although when the wash the truck it drips cause they have the hood up whos to say it didint splash where it wasnt supposed to.

If some complete idiot aligned the carrier bearing perfectly to the drive shaft then that could be a serious issue. It is supposed to be off by about 2-3 degrees (and bearing itself angled slightly) to prevent harmonics and drive-line jumping ... and a lot of people who replace them are completely clueless about this, assuming like fools that they are supposed to be in perfect straightness.

I think they may have it was done at kenworth dealer, after many people told me they had the best transmission guy in the area, thats proving to be wrong as he didint solve anything, but made it 10x worse. I really dont know whatelse to do. maybe time to give this up.
