I have a 97 gp gt with a 4t60e that I plan on replacing with a 4t65e hd that I already have. Is there a way to find out what sprocket set it has in it now. It seems to be 3.29 ratio from what I have read but I have not been able to find the number of teeth on the drive and driven gears. I need a 33 tooth driven gear. If that is what I have then I will use that one and have it machined.
