THINKING about doing this and wondering what I can expect

0w20 mobile1 in my festiva trans for the last few thousand miles. I have nothing but positive feelings about it so far. Throttle response is noticeably better and I've had my 2 best tanks yet

In my geo metro G10 5-speed I just replaced my engine oil with amsoil 5w-30 and the Trans fluid with Amsoil synchromesh... It feels good but I did some other mods at the same time so I can't give numbers... I do know the shifts feel better. I also have their Amsoil racing grease for bearings I'm exciting to try it out and see if I feel less rolling resistance when I do my brakes in about a week or two... And yea Im an Amsoil dealer lol
