    '02 Trailblazer LT tranny tune

    Anyone with this truck knows it suffers in fuel economy and sloppy shifts.

    I originally bought my HP Tuners to tune my Z06, but now this Trailblazer I just bought needs some serious help. Does anyone have a good, working tune for the tranny? I need to clean up the shifts, disable torque management, etc.

    Thanks in advance...

    p.s. I'm getting about 12.8mpg in the city with A/C.

    I used the economy tune from Justin and it helped firmed up my shifting and improved my gas mileage.

    I'd love to see this tune.
    I was thinking about playing with my Envoy.

    if anyone is looking for a i6/l60 TB tune I've got a really solid tune I've been working on. Averaging 15.7 mpg city and 21 hwy. i dont get a good mix very often, I'm either traveling with the family, or driving 7 miles to work..

    Firm and fast shifts, a little timing, TCC lockup adjustments - i think this is most of my fuel savings (could use some work on TCC, drives fine but locks up too early in that 3rd 4th gear area around 45mph, its on my to-do list to fix. wont be hard.) and much more done here. Feel free to provide feedback as well!

    Just got the truck a little over a month ago, up to about 2500 miles. I drove it for 2 gas tanks stock just to get a fair assumption of mileage and characteristics. Quick assessment of "it sucks". Stock the TBs are PIGS, slow as hell and sucks down gas. Mine now is a little less of a heffer and a little less of a guzzler. Still prefer the wife's 2500 burb :P But the TB is nice for cruising to the office and carting the kids around.
