Re: 2003 Mach1 / 3650 Tremec

Guess I'll be the first, and perhaps the last, to say I thought the special juice was not friendly to my trans. That lucas was too thick and took way too much time to get warm enough to thin out and let things slide in the trans. During colder months it was even worse. I dumped it and just used regular non synthetic atf and its the best it's ever been. Virtually no 1-2 grind when the trans is cold (i go slow on this shift until the trans gets some heat in it anyways so it doesn't grind at all). When it's warm it's perfect. I can shift in as fast as I need to. Been this way for 20k+ miles.
