Ok Guys, one more before I leave on vacation.
I got a 89 k5 Blazer That I'm putting a cummins 6bt into and need help finding a good Stand alone computer for the 4L80E I am going to use. Money is a big factor because I dont have very much. Any Ideas? Junkyard or a Cheap source? I already have a 1990 6BT intercooled, Adapter from a wrecked fritolay truck, flywheel, 4L80E with a 241 T-case, etc. I aint scared to fab my own motor mounts. So basically I need to wire up the Trans and figure all that stuff out. Any help or thoughts or Ideas would be appreciated. As soon as I get back from vacation I'll thank you guys.

Simple.

'91 - '93 GM.

4L80E stand-alone TCM, Harness.

Get it.

Do it.

Pre '94 with the 4L80E had stand alone ECM's. Wester garage sells upgrades for shift point improvement.

Ok....time to hit salvage yards when I get back. Thanks and maybe keep a eye out for me. We only have one salvage yard here and I know it doesnt have what I want. I will have to hit the bigger citys. Thanks.
