Just the FAQS Jack,,,,,, http://www.tciauto.com/tech_info/faq.htm My cooler story. I have an old 92 Bonneville daily driver. 210k on Mobil 1 (bought at 72k) valve job done at 110k. OE bottom end. This thing has ALWAYS had bad converter shake at highway speed when hot and all locked up. About 25k ago the plastic radiator decided it was time to go. The replacement I received had the wrong size trans cooler line fittings. Rather than go through the hassle of returning it (mail order) I decided to install a trans cooler that I had bought for another car but never used. It is a rather large one, about 12x16. The tube makes 6 passes back and forth through the fins. So I thought it would be big enough to cool the trans by it self. The first time on the interstate after installing the cooler I was shocked as the shaking was all but gone!! Apparently the shaking has something to do with heat and the new trans cooler had changed the temp of the trans. To this day the shaking is MUCH better than with the OE radiator cooler. It sets right in front of the A/C condenser so it gets a full blast of air. After driving around town that thing gets so hot you can barely touch it!! The auto trans gives off more heat than you think. Anyway that's my story and I'm stiiicckken to it. Bruce Hevner -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
