[me and my metro]

I run a 700r4 in my 84 1 ton GMC. The one to build is the 89-91, according to my transmission guy. At least get the pump from one of those. There is a lip that keeps the bushing from sliding. The one I have in now is a fresh 87 case and valve body with a 90 pump. It has 5 pinion planetaries and the Corvette servo with the aftermarket overdrive cover. I tow in overdrive all the time, the last rebuild lasted 10 years until a 4 pinion low planet failed. My truck is set up to tow not for economy, it has a na 6.5 and 4.56 gears.
