Here's my 2 cents... I run a glide on the street and the strip. I have had it in a 93 cobra and then we built a chevelle, so we put the glide in it...
Its a pretty simple tranny... no high dollar insides except for the converter, trans brake and a hardened input shaft. the car is 3,645 pounds with me in it. It does really well, I do have a tranny cooler with a elect. fan. so that helps. car runs 11.60's @ 115. Now down where you guys live it runs 10.80's. I'm in Colorado. I believe both tranny's are good but the glide does weigh a little less, and of course less rotating mass. That is my 2 cents, Hope your next tranny holds on a little better.
