I purchased my Mazda 626 back in Oct. 2001. I really wanted a 2000 Dodge Intrepid but was not pleased with the cornering of the vehicle (it leaned while turning corners). I drove the Mazda 626 and was impressed with its performance. About 70,000 miles later my tranny failed. At 89,000 it failed again. After intense investigations, I found out the trannys all overheated. Mazda did not install transmission coolers in these cars. ALL CARS HAVE THEM, EXCEPT THESE. I installed a $25 tranny cooler myself in about 15 minutes. This cooler could've saved me $4400. My Mazda has over 140k miles and runs like new. Why didn't the repair shop detect the root of the problem?
