And while you already have the TH325, consider swapping it for a TH325-4L. The latter is the four speed overdrive version of the TH325 and is based on the 200-4R. The TH325-4L should bolt in place of the TH325.
Hi Joe,thanks for the excellant info.I was wondering if i could convert to a 4 speed trans. I plan to do everthing you suggested!
Thanks much Joe,warmest regards,Jerry
