Help with Possible trannie problem

[Chad T]

Sorry I missed that Scott. Any other ideas? other than the tranny which I will run by a Shop I'm just asking around to see where to take it.

[Chad T]

Is there any body else out there that might have an Idea of the slippage and vibration problem? Thanks in advance

Did you just buy this truck or have you had it and it has just started doing this. it sounds like a u-joint or driveline angle problem to me. A u-joint could be dry and binding up but still feel tight with driveline installed. Try removing the driveline to check the u-joints.

I did just buy the Truck in Oct. and it has always done since purchase. I'll check the U-joint and if it was the torque or clutch it would start to smell burnt soon? I hope it's the U-joint. Thanks

[djsdiesel]

do you only get the shudder on take off?

[Chad T]

not on take off it's when you start to accelerate in motion at any speed it feels like it hesitates(sluggish)and vibrates and then if you continue it will smooth out as it picks up speed or if you let off the accelerator it will smooth out also quickly

[djsdiesel]

I would take it to a tranny shop and let them drive it, I misunderstood I thought it was on takeoff only. It does sound tranny related

[Chad T]

Thanks and the u-joint sounded better though.

Sorry about that Chad. I fotgot we were in the 7.3 tranny forum
Still asleep I guess

Anybody else have an idea. The only other info to add is it seems to do it when the tranny approaches the downshift point. thanks
