Thumbs up <TECH ONLY>TQ Mgmt removal revisited & other tranny performance tables

In addition to these settings:

Transmission











Engine






















What other things should we be looking at for performance applications?
Regarding the Shift Pressure Modifier tables what are the typical settings for performance oriented setups?
Is it really needed to lower/raise shift pressures based on tranny oil temp when used in conjunction with a shift kit?

Nope. Let the mechanical parts do the work.

I would just leave those tables stock. As i'd would be afraid of slippage when the transmission is cold. Granted, those can be tweaked of the shifting is excessivly harsh when cold.

Proper tweaking of the trans settings is good. But i would think that GM spent a lot of time studing fluid viscosities vs. holding power vs. temperatures when they programmed those tables.

what about the Force Motor Current table?

changing the 100psi column to 0ma

what would this do?

Also TCC Duty cycle?

what would this do?

makes for nice lock and unlock scenario (firmer) if you have a aftermarket converter. There is lots of opinions on this, but the opinions sem to range from one TCC manufacturer to the next. Mine is 98 and 98. not for any reason, just experimenting. I will more than likely end up at 100 and 95+.

The lower the Force Motor Current the higher the pressure, 0 would be max line pressure 200+. Most trucks I have seen have that colomn set at 1245 witch is little to no pressure.

Now from what I gather we should not even get into the 100 column unless we have bumped are max line pressure to 96 then there is a chance we might get into it on max load and we dont want to be bleeding off line pressure at this point. So its a good idea to set that column to match or less than the 96 column...

Thats what I was thinking, raising max pressure to 96 and zero'ing out the 100 column

I would leave the FMC table alone with a transgo. You are mechanically raising pressures already.

Not sure about the TCC duty cycle.
