Is there any kind of controller out for the 5AT transmission. I am looking for something that I can make it shift harder and be able to handle more power when I want it to and then drive normal when I want it to. I do not necessarily want to get the Stillen Valvebody due to warranty reasons. Oh btw I am a new owner of a 2006 Diamond Graphite sedan 5AT. Thanks for all the help guys/gals

 

not that i've ever heard of. i believe the cobb tuning tool lets you read (not set) TCM parameters. The Cipher tool does not yet do that, but they say they are committed to getting that done (but no timeframe) - again that is expected to be read only. Cipher does have a ECU flash tool that they do not yet distribute. If they crack the TCM code, then they might be able to flash that as well.

I think that's as close as the community has gotten to what you are looking for (outside of valve bodies and full transmission rebuilds).

 

Isnt our TCM a seperate computer that sits in the passenger kick panel ?

 

Unless you have an 04.5+ model where the TCM is integrated into the valve body.
