Newbie wondering about 6L80/6L90 Conversion.

[TBMSport]

Hey guys,

Basically, this is a bit of market research as I investigate which is the next vehicle and forum we become a sponsor of....provided we are fully successful next week (knock on wood).

As I plan to wrap up the first 6L80e conversion on a 5.3L V8 GMT360 Trailblazer next week the we decided to go with an off road build up rather than street, I figured...hmmm...maybe the Hummer H3/Colorado/Canyon guys would be interested in a bolt in kit that allows them to keep their cruise control also. I'm talking a total bolt in kit and you can keep your cruise control complete with new harness/ECM.

I'm not sure what all comes and doesn't come with the present kits on the market, but I believe we have cracked the code on how to get make late model GM vehicle (technically ANY vehicle) run with the 6L80E/6L90E computer system.

This project would have been done already had we not had the difficult issue of making a custom transmission to transfer case adapter and transfer case input shaft.

The following are among the "stickies" that we are addressing/have addressed and plan to made available in the total package and/or a la carte.

Utility Features:
-Use of factory cruise control
-Tap up/down shifting
-4.xx First gear ratio aids crawling
-Extra two intermediate gears will really help I-5 motors in acceleration.

Just as PURELY a rough gauge, for the TBSS AWD/4WD we're speculating an approximate $6000 (+/- $500) for the entire thing including labor. Some return could come from selling the 4L70 trans. About $1000 was allocated to labor costs, so there is a savings if you do it yourself. Off hand I believe an easy $2k of this is in the necessary 4WD/AWD specific upgrade components.

Although the Inline 5 will benefit most from this, the cost will be higher due to some additional components that will have to be made such as the transmission bellhousing. So while it's possible, it would be a slightly longer wait for you guys.
