I have a car with high milage (131,000) that I am going to use as my winter beater. I went to an oil change place to have the ATF & filter changed. I like the T-tech system because it flushes the converter also. Question: why would they ask me to sign a waiver in case shift problems develope? They do this for all high milers. Matt

 

Because it stirs up all the garbage built up in the trans, whats more amazing is they offer it with or without the filter change.
