transmission fluid

i got valvoline atf-3...is this ok, my neon has mercon dexron crap that the idiot i took my car to for a oil change....supposably it was just a top off, but i am replacing the whole thing including the filter, maybe this is why i have a vibration, i called him and ask him what he put in it and he said" a old bottle of mercon dexron"...what a dumbass!. Also what kind of cam gears should i put on my neon, i have heard horror stories about fidanza and do they really make that big of a difference

"You *must* use type 7176 transmission fluid in all Chrysler-built automatic transmissions since the mid-70's. Dexron II and III are much more slippery than type 7176/ATF+3 and will cause shuddering during shifts. The latest version of the Mopar ATF is Mopar ATF+4 type 7176. It is more heat resistant than the prior ATF+2/3 formula.

Yes, there are aftermarket equivalents for the Mopar ATF+ auto trans fluid. Here are a few fluids that meet Chrysler's MS7176D specs:

Citgo ATF type 7176
Esso (Canada) ATF+2 Type 7176
Kendall Type 7176 ATF
Quaker State 7176 ATF
Pennzoil 7176ATF
Texaco Texamatic Fluid CS 7176M
Valvoline ATF for Chrysler Vehicles

Redline is also a good substitute, from what I hear.

As far as cam gears go, AEM is what I would use. They have been proven on the neon. They will make a difference depending on what, if any, other supporting mods you have to justify the cam gears.

thanks man
