    Thanks DmaxMaverick, I feel much better about the trans. But the question now becomes, what will firm up the TC so that it doesn't lag so much between shifts. Second is pretty solid, but 3rd and 4th seem to take awhile to catch up with the rpm's. Is this what the TCM "learning" should do? Should I just use T/H when I'm looking for more firmness in the shifts? Or does one move up to a triple clutch TC? $$$.

    I don't think a triplelock TC is a good idea. You need the TC to take up the slack between the engine and a stock tranny. Take that away, and the tranny will become a failure point. The learn process will firm it up a bit over time, but will not be as firm as with stock power levels. The TC is calibrated for stock power, so forcing more through it will cause the slop. Use T/H if you want a more firm connection.

    The alternative is to upgrade the tranny and TC. The performance grades will hammer gears like a manual.

    I am running the same tune and mods in my 06 LBZ, but never felt any slipage.

    Would the Transgo Jr be enough to overcome this issue and get a really solid feel? I can feel the defueling during shifts now, perhaps this is all Jeff feels?
