I'm willing to bring that car back to Virginia and work out all the bugs so you don't have to worry about its reliability.

I'll be gentle with her.

Haha, for now, I will live with the uncertainty!

Haha I will see what I can come up with.

As of now, I think that a lot of the driveline noise that I am hearing is a result of installing Delrin bushings between the upper shifter arm and the transmission (the thing that the infamous "bitch clip" goes through). I will be double-checking that I tightened all of the various mounting bolts, and that I have fluid in the tranny, this weekend. I am pretty darn sure that I did, so the noisiness is something that I will either need to live with, or go back to a nice rubber shift arm bushing! The shifter does feel a lot crisper now, though...decisions, decisions!

I suspect you're correct about the delrin bushings. I installed a B&M shifter in my old Jeep TJ and noticed a buzzy noise from the transmission. I realized it went away when I held my hand on the plastic T-handle, so I switched back to the stock rubber shift knob and the noise went away.

Glad to hear you are loving the new engine!

Thanks! I met my dad at lunch and drive around a bit. Yeah, there is some rattling going on in the driveline, but I do not think it is too sinister. The rattle at idle seems to have gotten the nickname "Getrag Rattle" across the internet so that's probably fine. I still swear that I get new ratling noises when decelerating / engine braking and sometimes on the highway, but it could honestly be something existing. Maybe I just need to step back and relax lol. I will get under there this weekend and double-check all of the fasteners in the driveline, and see about using UUC's recommended gear oil + tranny lube mix to quiet things down.

The rattle is worse with synthetic fluids. I used some Lucas gear oil mixed in mine to help combat the noise.

I noticed the noise once after doing the clutch the first time. Thought I did something wrong. Nope. I was just listening more closely than before since I was paranoid!

If everything checks out OK, just roll with it!

Yeah, so far things seem fine. Over the weekend I removed the RedLine MTL and put in RedLine MT-90 (GL-4 stuff, NOT the GL-5...GL-5 fluid is for LSDs and will eat the synchros). It helped a bit since it is thicker, but I'll just have to live with the noise.

The rattle at idle does not bug me too much. I am still a little weary of the gear noise during acceleration and endgine braking, but I didn't find excessive metal chips in the tranny when I drained the fluid so it is probably just the disengaged gears on the output shaft rattling against their partners on the layshaft. I also get a little tranny grumble on the highway, but I think it is OK. At least I have a spare G240 lol. Aside from the noise, it shifts smooth, runs smooth and my mileage is great!

At 70mph on flat highway with no wind, the MPG needle is pegged at ~38, which is definitely better than with the old stock engine. Gotta love higher compression!
