Replaced the gasket and so the trans is basically empty at this point. It has been suggested to me to remove both check valves and pour some fluid down in both ports, then reinstall valves and rotate the driveshaft (or in my case the coupling arm since there is no engine in the tractor right now) in the direction of normal rotation (I think this is counter-clockwise but not certain till I refer to my notes) to make sure the pump is primed. Never had the check valves out before so wanted to make sure I need to do this (?)

Thanks...

Good morning guys! I too have replaced about 4-5 of these gaskets. I always thought it a good time to remove the rear cover and clean out any sludge or dirt, and thus reassemble and refill through the hole in the rear cover.

Hi Al! Now, on my model 1211I had tried to fill the trans through the relief valve and what a episode that was lol! Same thing happened to me.... oil everywhere! What's not to like about my model is that there is no fill hole in the rear cover, ( something that's worked for decades) so it was a long, painful process to refill through that tiny little "dip-stick" tube they got going on. I was not about to break the new seal I made for the rear cover.
