2007 Silverado Vortex MAX 6.0 Shift
I recently purchased the new Silverado LTZwith the 6.0 Liter motor with high performance suspension. I feel the truck shifts poorly and at times bogs down between the 3-2 shift. I am unhappy with the performance at low speeds. I brought this to Chevy's attention and they say it normal - I disagree. I am thinking of installing a superchip to see if that helps.
Is anyone else having this problem and can anyone post reccomendations. I love the body style, interior, and hate the way this thing shifts. Oh ya - the truck is governed at 92 MPH. This is way too slow for this motor.
Also, the back-up sensors won't work if you leave the hitch in the reciever - I think this is a design oversite? Again Chevy claims this is normal - my F-150 did not have this problem. Can this be adjusted?

Yes a programmer can change shift points. Just be aware if you tranny fails you may void part of your warranty if the programmer is found to be a contributor to the failure.

RE: 2007 Silverado Vortex MAX 6.0 Shift
I'm looking at Superchip 2815. I called and looked at the product on the internet. The unit saves factory settings and then reprgrams the truck -this way you can go back to OEM The new part only has preprogramed shift points. They sayit may reprogrammed at a leter date to allow manaul changes to each shift point. You down load the prgram onto your unti so it remains current. Again I haven't tried this. So I am looking for anyone hwho has some experience on this?

RE: 2007 Silverado Vortex MAX 6.0 Shift UPDATE
UPDATE: To make a long story short. Chevy said the truck was normal while the local tech at the dealer felt it was a software issue. I am happy to report that Superchip 2815 solved many of the issues I had with shift and performance. I wish OEM worked better, but at least my issues are resolved for now. With my 6.0 motor the programmer made a noticbale difference and I have itset at the lowest performance (87 Octane) because any other option requires 91 octane. Also if you tow and use the programmer, you have to download the tow software into the truck- it comes with the unitthat requires 91 octane. Hopefully Chevy will issue new software in the future, but for now, I will burn some rubber and enjoy the truck. This unit allows you to change the speed limiter stock is 90mph and many othr fetures - its pretty cool. Im sure others do the same.
