Did you not read what I posted in the other thread you started on this very same subject :eeek:

the thick stuff.....

and...."changed"??.....

I don't know what you're refering too.....

and really.....its a 205.....you could put used oil from your crankcase in it and it'd still outlive the rest of your rig...

Crash correct me if I'm wrong but I thought I read somewhere that if it is in back of an auto they came with atf I'm not sure but I thought I read that.

I have never seen one with atf--I see 208's with atf....

Yes some of the 205's did come with ATF though I don't know the applications off the top of my head. From what I understand the reason for this is there is no seal between the trans and T case so they share the same fluid. If you put 90 wt in one of these your likely to ruin your transmission...

Thats right--there is no seal on the t-case itself--but on the adpater there is a seal that rides on the outer surface of the 205 input if memory serves me correctly. I don't ever recall any production vehicle --with an auto that shares the same fluid.
