Hey all. As you see in my sig, I have a '97 GT with 3.55s and a few other mods done to it. What I've noticed basically since I got the car is that my transmission does not like quick 1-->2 shifts, and tends to grind if I am shifting really quickly. What bothers me more is that the problem is hit or miss... ie it happens sometimes, and then shifts fine other times. Usually it grinds in the cold (which I've been reading happens to a lot of people). I changed my tranny fluid to Castrol Dextron III mercon, which didnt really do much of anything. I know it isnt the TOB because otherwise my 3-4 shifts (which are usually really quick) would grind. So i was thinking maybe it is the syncro, or maybe I just need to let the transmission warm up more before going hard on it? I was thinking that if it was the syncro, it would grind consistently, but it doesnt. Just a couple weeks ago before I retired the car for the winter, I spun up the tires and ripped second really hard with no grinds, but the car was warm. Well, sorry for the long post... I realize there is a whole thread on the 3650 grind problem but this isnt the same tranny and definitely doesnt seem to be a mechanical problem. Any help would be greatly appreciated!
