http://www.granatellimotorsports.com/pdf/manual34.pdf This is the link to the installation manual for Granatelli's GM tranmission tuner. It is a direct plug in between connectors. I emailed their tech dept. and they said it will work with an 05 SSR, part #420102. Has anyone tried this in their 05? It is under $130.00 and has adjustable shift firmness up to 30 psi and also something with torque convertor lockup, but that bit is beyond my understanding.
I know when all the tuners catch up and start offering microtuners for our 05 models this will be offered. However, I thought this might be a nice option if someone ( me ) only wanted a firmer shift without using a mechanical shift kit. What are your thoughts???

So they put the 4l80E in the 05 models...hmmmm
Boosted - My books show a 4L65E for the 05. I have inquired with TCI Transmissions and they do make an "updated" 4L60E for the 04 SSR, plus a heavy duty converter. I have seen other notable vendors in my myriad of car magazines who also supply "updated" 4L60E transmissions. I've used TCI back in my racing days and now when refurbishing muscle cars, when I have time.

I had a 94 Z-28 with a 4l60e transmission and I had a jet performance transmission control module on it and it made a tremendous difference. This thing had 4 settings and the last setting was race mode and it would chirp the 1-2 shift so hard it I swear I was scared. Rock solid shifts and by the " seat of the pants " meter, faster. Unfortunately Jet doesn't seem to have one for an 05 SSR. I guess by years end there will be some more performance stuff out for the 05. I"m no pro on this stuff just know from what I've used on some of my previos F- body cars.
