Then it isn't lifters. I see no way they can be affected by which gear you're in. A gearbox fault would be the logical deduction.

Take the plastic cover off between the engine and trans. Make sure that all the torque converter bolts are tight. A lifter soud is more of a tick. You might also have a cracked or broken flywheel.

I'm sorry if I did not clarify in my original message. I want an easy answer. All the talk about timing chains and flywheels make me dread actually getting into the engine. Or worse yet, taking it to a repair shop and handing them the keys to my live savings. :) Thanks for all the help.

I would first be suspecting a weak engine mount letting some part of the exhaust hit the vehicle.

Yep! That Dog-Bone can do it. I had to do that on my '87 2.8l V6.

Easy repair though! :)
