The torque converter clutch should.not be the problem, because its not engaged in reverse.
Did you check under the.jeep with a helper inside with its foot on the brake, if you can see/ hear/ feel something abnormal? Put chocks on the wheels for safety when doing this.
Yeah I'm starting to think its one of the engine mounts. I did check for funny noises in the engine bay and under the car while its shuddering and because the diesel engine is quite noisy, you cant really hear anything out of the ordinary.
After a drive that's 30+ minutes it will almost always shudder in reverse while stopped. I opened the hood to look this time and I noticed the engine is vibrating quite a lot. Put it into D, N, or P and it is smooth. Put it back into R and it vibrates. That must be where the shuddering comes from.
I got a flashlight and inspected the rubber isolators and they don't look perished or anything. Is there anyway too check them besides just replacing them? (they're $200+ each and it looks like Ill need an engine lift to change them).
