Hey guys. I just purchased an '09 9-7X(Trailblazer I6) with 70k miles. I have the service records and the transmission has not been touched yet. I am going to drop the pan for a filter and while I am there do an easy upgrade. I drive very spirited and I'll trailer my car to the track a good amount. What are the easiest things to do now other than a tune?

I was piecing stuff together then remembered Jeff has kits. This Trutech kit with the addition of the Sonnax 4th servo pretty much has me covered right?

Yes, that TruTech kit looks comprehensive. Although they say its "not a shift kit", it really is. Price is reasonable since it includes a new separator plate and Corvette 2nd servo.
Yes, since you plan to pull a heavy trailer, I would add the Sonnax 4th servo piston.
Ask Jeff if he would recommend the Sonnax 2nd servo to go with it.
And remind him to become a sponsor here.

 

Will do. Ill call him later and order.
