Greetings everyone,My name is Bob Richardson from NY and I'm new here. I got this Site from one of the Corvette guys. My 6-speed calls for a ATF transmission fluid. I did switch to Red Line MTL with great results (no more gear lash)...but...I'm worried about the soft metal issue.I am about ready to try Royal Purple Synchromax. They state that it is recommended for manual transmissions that specify an automatic transmission fluid or motor oil.I hope it's everything I'm looking for in a trans oil.
