Please let us know what you find out about the vibration on your truck. When you get a chance, read through the sticky threads at the top of the forum and set up a gallery with some pictures of your truck. We all love to see pictures of trucks in various stages of modification or restoration.

Vibration found. I replaced the motor mount and fan clutch as identified by the tranny shop...no luck. Called the tranny shop and the owner (great guy) said "I don't think it's in the transmission but bring it in anyway". He found the problem between the transmission and the transfer case. A couple of the bolts had broken causing the virbration and wearing out the transfer case seal...which caused the fluid to start leaking. It's running great. Oh, the repair cost $350.00 and damn glad to pay it.

Vibrations can be tricky to diagnose, but here's some easy checks to make: bring it up to speed where the vibration comes in, then put it into neutral and let off the gas. Rev the engine through the rpm range it was at during the vibration while still at speed, if the vibration comes and goes with engine rpm then you have already narrowed down your problem. I had a bad torque converter once and found it that way. The other thing to check is the frequency of the vibration and this is just seat-of-the-pants judgement, ask yourself "does it feel like the vibration is at about the same speed as the wheels turning or is it about 3 times as fast?". Most vibrations that are speed related are wheel balance problems. If it feels like it is about 3 times as fast as the wheels are turning, then you may have a driveline related problem.
