I think I'll leave it off. Also been looking at the shift improver kit by transgo that says to address all the issues we were talking about. Poor 3rd clutch band, poor lube & all that. From all the problems I have read about the re4r03a has they have listed as addressing in their kit. So maybe a used tranny, new filter, & their kit before installing it, along with a tranny cooler it might last for a little bit?
