I was thinking.... In the Barth, Lovestogo has the GM Turbo Hydramatic 400 3 speed automatic transmission. Since I'm dreaming with his money, why not stay with a GM transmission, instead of installing the Gear Vendors overdrive unit? The GV hardware is something like $2-$3K plus installation. Yank the 400 and sell it, you might get a few hundred to a thousand. Then, go with a follow on transmission that GM developed, the 4L85E. Info on this I found: http://en.wikipedia.org/wiki/GM_4L80-E_transmission cutaway picture: http://media.gm.com/us/powertrain/en/product_services/2...0MN8%20BFL%20LoR.jpg 2007 specs sheet, Excel format: http://media.gm.com/us/powertrain/en/product_services/2...ries%20(MT1,MN8).xls Product description sheet, Word format: http://media.gm.com/us/powertrain/en/product_services/2...ats%20New/07_MN8.doc Happy Thanksgiving!

The 400 is a stronger transmission. The 4L80E requires a computer to operate. The 4L80E is expensive to repair, and requires more skill. The main advantage of a 4L80E is the lockup torque converter. It saves a little gas and runs a lot cooler. . 84 30T PeeThirty-Something, 502 powered | |||

Final drive on the 4L80E is also an overdrive. I'm pleased with the performance, although it's busy...
