Lube …or lack there of…

I do blame myself for not checking something so simple sooner. I know better and there is no excuse for waiting till it gave me trouble popping out of gear on that 200mi road trip.

Drained some thick, milky, surprisingly not sludgy, crap from the differential and almost nothing from the transmission. …seriously, maybe a 1/2 Cup came out. Dark black too.

Now that they’re filled with nice clean fresh gear oil the transmission is quiet and it shifts wonderfully. …go figure. 😛

.

The manual says 4 pints 80W90 multi-purpose GL-5 for the rearend and 1.5pts for the Chev 3OTT. I filled em both till the tip of my pinky (stuck in the filler hole and slightly bent) got wet.

[edit]   If you’ve stumbled across this while looking for info on draining the differential on an AD truck … the bottom dif cover bolt is the drain.

You’re welcome.
