BA_GS400 Posted December 13, 2004 Share Posted December 13, 2004 Just for reference, I have the PI torque converter. I HIGHLY recommend getting a tranny cooler for it, expecially if you do much stop and go or even a little in-town driving. I think there was an earlier question about installing the TC yourself. If you've done heavy car work in the past, I'm sure you can do this too, but, unless you've got the stands, a friend, a tranny jack and a full Sat. afternoon, you might want to leave it to a tranny shop or to a Lexus/Toyota shop. I've done a handful of trannys and STILL opted to have a shop do it! :) I ran my TC without a cooler for approx. 3 weeks until I was able to get the cooler installed. During those 3 weeks, I had no less than *THREE* separate occurances where I could SMELL my tranny fluid! Since the cooler install, not a single instance. BTW, I drive pretty aggressively, hence, I'm usually makin' the converter work hard. ;) Oh yeah, I did get a bonafide 4-5 tenths improvement at the dragstrip.
