Manual Swap

[CSFJ]

Hey I have a 1973 Chevy k-10, im currently upgrading my tranny from a old 3 speed to a tko600 6 speed. If you want the original one you could buy my old transmission (3speed manual for 4wd, but it needs rebuilding. Otherwise id buy a tko 600.

What did a tko600 originally come in?

It matters not for a 4x4 application, if you have one of those lowered contraptions that might go fast it would be a great tranny. Here are the specs straight from the Tremec site:
