Ok, guys-
Dad and I have wrassled the old Burb until she's just about submitted to our demands, except this: now, the noise we thought was the transfer case or rear axle is pretty certain to be transmission noise. Previously described as a gear whine sounding like a bad, bad power steering pump whine, but now accompanied by a serious gear whine-scraping sound in first gear only in the Burban, 180,000 miles, 22,000 on the first quality rebuild on the 700r4, virtually no hard miles/towing since the rebuild. Having destroyed a TH350 in a '84 Burban by running it hotter than he## and towing the USS North Carolina at 75 mph like we were somebody, abuse since the rebuild is not the situation here, instead, it sounds like the planetaries are whining and grinding, and like the TH 350 in the '84, I reckon they're about to self-destruct.
So, the issue is: would a professionally rebuilt 700r4 job have had anything to do with the planetaries, and whether or not, if they're gone, what now? We say that because despite the fact that we're way beyond the agreed-to warranty on the rebuild, we believe the trans shop will at least work with us if there are/were any gear-related work they were to do on the rebuild.
On this truck, like said, the body and motor are good, maybe great. New suspension parts abound, including new-from-the-box rear leaf springs, all new shocks, new steering stabil, new ignition parts--running like never before. Doing some transmission work to perfect the "restoration" is a no-brainer.
Part of me says repair the auto (having NO IDEA what is involved if the planetaries are futzed up), and part says: Put a 5-speed in there and fuggataboutit. A crate 700 of some sort is certainly in the range of possibilities, too. Any ideas as to source, costs?
This much is certain: I have no problems with the 700 as such--see previous threads, recently, as to my faith in that gearbox. If I stay automatic, a repaired/restored/crate 700 would be a dream to me--I'm primarily interested in the feasability/cost comparison in getting either a crate 700 vs reparing the gear-broken one I have vs switching to a manual. The uniqueness of a 5-speed is there, I must say. This truck has 3.73 gears, runs smoother than a sewing machine, and would father a manual for a long, long time.
Don't hate her because she's beautiful, OK? Serious thoughts and suggestions, please.
