It went into the red more than once but I didn't have the funds to fix it at the time.

You replaced the whole engine or just the cam and rockers? I hope the later!

Pre 89 models have the older style camshafts that score as shown in the photos -- even moreso if you don't run diesel-grade oil with the zinc additives that our cams REQUIRE.
That is why it is imperative that you keep oil changes 3-4k and use of diesel-grade oil such as Rotella-T 15-40.

Make sure your tranny gets the front pump resealed and b3 bands replaced, once that is done, the 722.3's are bulletproof. They rarely fail. Since it shifts fine, leave it alone other than the pump + B3!

Awesome. Thanks ps2cho. And no, it is the whole engine

Update...Transmission has been rebuilt. I found a guy in Orange County called the "Transmeister" and he only does MB trannies. He told me all I should need based on my symptoms are the b3 friction discs replaced and front pump resealed (as well as a new gasket and filter). Well, that would have been it but he also found a cracked b1 piston case that cost 107.00 and was causing the clickety sound in reverse. So, $500.00 later, it should be rock solid now. Everyone else wanted to do a full rebuild or just put in a remanufactured tranny. Thanks ps2cho!
I am just waiting for the replacement engine to get put in now, connected, and fired up. The mechanic had the engine out and the tranny in 6 hours without a lift and by himself. So, I'm guessing it'll be ready tomorrow...
