When I was running the MTL my trans too was notchy at first when still cold shifting. When the trans got warm it was better. When I swapped motors I put some atf+3 in and it was much better shifting and way smoother. My trans has about 60K on it and it had atf+3 in it when i bought it. My Eo trans with 98K worked fine from what I know and also had atf+3. My guess is if you know how to actually drive stick and use the clutch your tranny might have a better chance at survival even if using atf+3. (I'm not pointing any fingers saying anyone here can't drive stick.)
