The drain plug idea looks great. did he say he got the plug at Harbor Freight, or an auto parts store?
I think I am going to try to do it when i drop the OD pan as my next adventure.
I got the fluid, just waiting on the pan gasket to arrive.
also, should I use RTV on both sides, the pan to gasket, and the gasket to trans? and which RTV is best?
thanks for all the help I appreciate it.

While you have the drain pan off of the OD, id suggest flushing the cooler lines too. I think what i used was called Kooler Kleener.

I know the t10 is fill until it comes back out the fill hole on level ground and the OD is the same? I don't remember for the OD.
T10 is definitely fill until it comes back at you. And be sure to use the GL4 specific oil for that trans, I used sta lube GL4.

I'll be honest with you, I have never read the owners manual for my 85. That's interesting.
However, if you Google "what gear oil for a super t10" every single forum and article that comes up says stay away from gl5 for a t10 or super t10.

I don't know that the use of what you mention to be a 'desired' use! All bearings in the T10 and other (similar) are 'ball' with the exception of the counter-shaft and the ZF is Metric 'needle roller'. Caged ball and tapered cone/race I believe have different requirements. 'Yellow Metals' have nothing to do with it. I do understand your mention of 'Yellow Metals'! I believe currently many use and suggest GL4 85W90 and NEVER 85W90 that has the additive for 'differential clutch-packs'. Newer GL5 so long as it's MT1 approved is mentioned often also. All lubricants have certainly changed through the years.
