whats the gap between the converter and flexplate when you installed it? did the tranmission go back to the block easy or did you use the bolts to make it go back? did the converter make 2 clunks that is all the way on. did the converter snout go into the crank smooth? also check all the bolts in the converter. honestly the converter wont make the drivehshaft shake. i cant see exhaust shaking the steering wheel. exhaust has nothing to do with the steering.
why you didnt mention this yesterday when we was texting about it?
its hard to determine this without seeing the truck in person.

Everything went on fine. All 3 converter bolts were tight with locktite. It really is hard to explain over the forums. I might bring it to gerry lane today and see if they can figure it out. lol I do alot of business with them so i'm sure they can help me out. Oh yea and i didnt not use the bolts to make it go back. I know the converter is installed right because i'm driving it back and forth to work and everything is working fine besides that damn noise under the dash.. lol

#PIT4505C: Rattle Buzz Tick Noise From Front Of Dash - keywords accel bulkhead compartment engine hood I/P IP knock rpm stop under vibration - (Mar 29, 2010)

This PI was superseded to update model years. Please discard PIT4505B.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment on a rattle, buzz, tick, or vibration type noise that appears to be coming from the center of the dash. Root cause may be the transmission dipstick tube contacting the front of dash (cowl). If the transmission dipstick tube is too far rearward, it will contact the front of dash and vibrate, buzz, etc. causing the noise to sound like it is inside the dash area.
Recommendation/Instructions:
To correct this concern adjust/bend the transmission dipstick tube away from the front of dash/cowl to provide additional clearance.
Note: When inspecting or adjusting the transmission dipstick tube it may appear to have enough clearance with the vehicle stopped. Verify that there is enough clearance to allow for powertrain movement during acceleration and deceleration. Inspect for contact while shifting between drive and reverse.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Keep us posted. I also see a number of knee bolsters(trim panel below the steering wheel) come through the shop because of a rattle noise. This could amplify the noise from a vibration caused by one of the above problems. I want to wager what your feeling in the steering wheel is a vibration that is traveling through the frame and body but not directly connected to the steering system because I can't link the symptoms in my head any other way.
