Conversions & Hybrids - Need A E40 ECM And T42 TCM Combo

Not sure if this is the right forum or not

I'm doing a L33 swap into my 04 Colorado, in order to do this and have it work in the colorado I was told I need to pick up a 05-06 E40 ECM and a T42 TCM.

I found a few E40s from 3.8 grand prixs which will work for various prices which of course will need flash to a 05-06 Trailblazer programming. Well I need a T42 TCM as well since the 04 colorado doesn't have one. Someone said there are some place that sell both sets for 300 already programmed. Anyone have any thoughts on places? I found some that will do the programming and some selling the computers but for more.

So any good places for me to go? or should I just try to get lucky on ebay and yards and get a dealer to flash them?

before someone asks the factory L33 Wiring will be modified for the E40

I've got an extra T42 that I bought and never used. I will sell it if your interested. $50 shipped.

I just might take you up on that. what vehicle was it from?

I believe it was from an Express Van but i'm not 100% positive. I bought it last summer.

Well I got a ECM and a TCM combo being programmed with a baseline 06 TB SS program for 315 ;-)

Sweet!

yeah actually ended up being cheaper consideringa dealer would charge me 100-150 to flash per unit
