Good job on forward thinking GM.

The $2k tran I'm referring to is fully built with billet components, so the price is actually super cheap for what it is. He originally sold it for $4500 and took it back on trade for a powerglide. This guy runs a respected performance shop, so he doesn't do stock rebuilds often. He's def. not the cheapest option.

I can get a 4l60e for around $400 locally, but the 4l65e's have been quite a bit more. Feels like once someone tears down a 100k mile trans to swap the output shaft.....they'll find plenty of things that need to be freshened up. I think the LQ9 will eat up a stock 4l60e, so a 4l65e it is.

good to know. i am not a off roader so i never looked into it. i recently purchased a 2003 chevy truck 4x4 with 5.3/4l60e that will go into a friends scout later this year or sometime next year. the only issue we could see was the new(er) t-case had the front drive line on the wrong side for the scout project and considered either changing front axle or changing t-case. it is setting on a pallet next to the scout and neither of us have looked twice at it since it was pulled out because we are both working on other LS swap projects. i will have to remember this subject when the time comes.
