Foamy Transmission Oil

Snychro, yes same, Penrite Transoil T250.

Yes, that is exactly the one. It also comes in a 140 and 90 grade but that is beside the point now. I think there must be something out of the ordinary happening in your gearbox. I have never had nor even heard of a foaming problem. Puzzling!
 
Y-Blockhead;
I know this is probably of little use, but I had the exact same thing happen to mine. Foamed something fierce! This was a mostly rebuilt ****** that I did myself and cleaned and dried the transmission case completely. It was a total car rebuild. I used the 600w from Snyders.


I couldn't figure it out either, so after some time I drained it out and replaced it with the same product. It hasn't foamed since. I still don't know why, but the condition is resolved.
