Rebuild service dilemma

Yeah I was skeptical the “break in” would matter and I was not thrilled about driving 1k just to come back to this. Def won’t forget, Ill need earbuds for awhile.

 

Dude if it's seriously that loud quit screwing around and take it in to get fixed!! Drive it another 50 miles, tell em you're sick of it and you want it fixed right. No point in risking something going wrong and ruining the whole tranny. Do what you think you need to, don't let the shop make you wait if you feel like it needs to be fixed now. Obviously something's wrong and it ain't gonna fix itself. Do it once. Do it right.

And btw I stand corrected on my previous post as you appear to have the R150F trans and not a W series. I don't really hear of it that being as common an issue with the R series. Just get er fixed!!

 

can't wait for the conclusion, take a 1000 mile road trip then switch trannys lol.

 

Funny my W56 series with about 250,000 miles don`t whine nor the fresh rebuilt ones .

Then OP having the 3.4 should have the R150F but who can really know I have seen to many strange things in these trucks

 

Get it in writing. I've been burned by 'long standing great community loved businesses' for trusting crap they said they'd do but I never got it in writing. If nothing is contractual, they'll give you the run around until you get tired and bored and they keep the money.
I would hurry and do the thousand miles in a weekend so it's all still fresh in their mind. Tranny shop told your engine shop 'thousand mile break in period' and that's straight up BS and engine shop knows it as well. They're not dumb.
Protect yourself and document everything.

Can you tell the transmission actually has been rebuilt? Sounds like they threw a used one in hoping for the best and were hoping customer doesn't notice it. New transmission will not whine, period. Whine comes from pitting and wear in bearings. Brand new bearings in rebuilt transmissions do not have pitting or scoring. How did they not notice those bearings with their wear, if they truly went through the transmission?
Hurry through those 'break in' thousand miles, it's in your best interest.

If i was in your shoes, I'd find a good used transmission, not a rebuild-nobody rebuilds these things right, and get the engine shop to get the tranny shop to R&R it with a known good used. Rebuilds suck, just like reman starters and alternators. If you could find a good rebuilder, that would be one thing.
And maybe tranny shop that engine shop subbed the work off too, of course engine builder wants his piece of the pie too for doing zero labor, could pull your noisy tranny and replace those countershaft bearings. But I wouldn't trust them too in your situation.
Good luck, keep us posted. I feel for you man
