I've tried searching for this on the web but no success. Does anyone know if I can alter the auto's shift points? I was hoping to stop it from going into 5th/6th gears at city speeds - maybe only after 80km/h or so.

 

You'd probably need to buy a programmer/get a custom tune to your liking to do it.

 

I agree with herbz.

 

I agree also. i had a Diablo programmer for my 04 auto and was able to change all shift rpm's as well as fuel cut off and some other stuff.

 

tune it for the win

 

Agree with above. A tuner will enable ability to change..probably worth it anyway for some other "tricks" they build in
I have SCT X3 tuner from Bama...good product and service

 

Tell me more about that tuner. What is the biggest difference you've noticed? I was looking at that Trinity with the Bama tune, and C&L cold air, but man it's pricey.

 

You should contact Brenspeed...they probably have the tuner you need site. Site address as follows http://www.google.ca/url?sa=t&source...jXYM_4Q9qQ5HMg

 

The old saying "you get what you pay etc" applies to me in this case

 

best guy in the buisness for the new 5.0 is jon lund
