Check plugs after a while. If you're rich, it'll show.

I love my transgo but just make sure u get a pollyurthane trans mount with ur install. I guarentee ur old rubber one will break off with that transgo. All the tranny shops have told me that and my buddy put a shift kit in his 700r4 and he busted his old mount of too. Vibrated all the way to the tranny shop. There only 20 bucks and its good insurance, just make sure u lube them up when u install it and a day after driving.

well i have a solid mount in there now...when i first bought the car the original tranny mount was toast...it was in about one million seven hundred and forty seven pieces we couldnt figure out why when i stomped trhe gas it clunked real bad man i knew absolutly nothing about cars before the camaro started breaking all the time

anyways did it firm up the shifts alot? and does it allow you to shift into any gear at any rpm?

Oh yeah, firmed it up very nicely. I can break my tires loose really easily. I am used to the shifts now but when I take people for rides they go "holy sh*t this thing shifts hard!"

It comes with a step by step install video but I watched it and repeated to say "Um, ok I don't have that tool, what is that thing, oh crap, I know I would loose that" :sillylol: So I let these tranny people I know real well do it for me for about 150 I believe and that was including the gasket, filter and fluid.

i got a 125$ qoute but i dont trust people so i didnt get it installed yet. i may have to go down there and get it installed soon. maybe the extra line pressure will help the 2-3 shift...sometimes at WOT it wont come out of 2nd...usually only if im racing somebody (dont worry i dont race fast cars )
