Sweet ride! I prefer the 4L80 for work over the 6spds. If you run the e38 ECM you can get a Van TCM from 07 thats compatible and will control the 4L80

Nice find dude

See i want the 6L80/90 cause the gearing is more favorable. If i was going for big power, 4L80 all the time, but it's a cruiser/tow pig. 6L90 will kill a 4L80 in that.

With a stockish stall I agree. With a well matched cam and converter? Not so much. A good converter really makes or breaks an auto build but there is the heat factor to consider, and a good stall does put more load on the engine. A 6.2L 4L80 with a 220ish/230ish cam and a high end stall would be a beast!

I'd run a gigantic trans cooler for this though. In Texas? maybe as physically large as the rad itself for worry free towing. The 6spd and stockish stall does make sense on a heat level if you run a smaller cam that wont drive through it

Yea this isn't a race truck. and like the gearing advantage of a 6L over the 4L80. Hell even highway speeds in it for cruising, it's got 4-500 rpm drop at only 70mph! And 6L80 can take plenty of power, they come factory on cars with LSA...

Ironically I just picked up a 6l80 2x4 trans today. Clean shape, good deal, might try it with this 6.2 I got. I have read there is quite a bit of OS bs with regards to the ECM/TCM can bus so if you get a 6l80 be sure its year correct to your ecm or you might be stuck. Theres flashes that can be done but a hard line in 2009 that cant be crossed. 06-09 ECM/TCM are unique to each other and so are 2010+ versions. Thought this info might be of help

I'm from west Texas (or do you mean the city "West"?).

That information is absolutely useful. Thank you.
