I am actually looking to do a substantial amount of tuning because I hate my 4l60E. I also want to try and preserve it so it doesn't blow up prematurly.

I compared a stock bin to a hypertech modified bin, and the only tranny tables that changed was "Force Motor Current (ma.) Vs Press Vs Trans Temp" And the values were lower

Isn't the hypertech supposed to provide firmer shifts?

I have looked around and seen many different diagrams of what the different engine-related tables do, however the transmission related stuff is pretty weak. Anybody know of a good source for tranny specific stuff?

Also, I am having a lot of problems with the TCC slipping, especially on the freeway, where at 70-75 mph the slip is a good 200-300 RPM I was "lucky" enough to catch it when scanning the system. Would increasing tranny pressure help hold it, or would that do more harm than good? Also, swhould the DC of the TCC really be at 90% anytime you go over 6mph? Doesn't seem right to me.....

Thanks in advance for any input you have. I'm starting at the bottom with this TunerCAT stuff (But boy is it cool! )

 

Haey... anyone got an answer to this one yet?
