I don't know much about trackers but with GM in the picture I believe it will need a specific type of ATF GM style you know dexcool coolant crap the red antifreeze

Dexcool didn't even come into the picture with most of the GM line-up till the mid 90's. The Tracker doesn't use anything special as far as transmission fluid is concerned. Just basic Dexron-Mercon. And is your statement to try to compare the Dexcool with what special fluid the transmission might take or thinking one is the other?

i have heard the same thing as well but most people say if it hasent been done on a regualar basis then use a additive such as lucas when changing it
