ive had my shift kit from mike at mv automatics for like 9months maybe a year and it has been fine i always check fluid in auto to see if it was burning but its still a nice red color
spun me out the first time i got back in the car from mike take off and changes gear alot more solid fills good when you give a little test and chirps my 19 no worries but be careful in the wet he will say i can vouch for that.
get it and see what a real auto feels like.
hasnt screwed my box or diff yet
