Started a new thread from the link. The 20W is the standard transmission fluid I've always used. Going to see if the 50W mixed in will current fluid will help with slippage.

Will see if putting in the 50W will allow me to drive it till summer so I can finish off a few other things before selling it. Will add one to two quarts of the 306 5W-30 with each oil change for higher performance besides quieter engine.
