Acutally I have one of each. I have had the 5speed(getrag) in my 93(140,000 miles on this one. The 90 I aquired several months ago and it has a 727 in it(160,000) on it right now.
I prefer manuals, I got this auto to use it as an offroad truck, and maybe someday some mudracing, so the auto is a +. I just don't like a transmission thinking more than the driver.
