You need to shim your accumulators if you want chirping power shifts...

Right. This mod just seems to freshen up the trans and make it feel newer and less sloppy. But nothing crazy where other people riding would comment on it.sigpic

Well it's perfectly acceptable right now
When I get around to it I'll try and shim the accumulators when I change out the fluid for the Dex-VI and put in my drain plug.Comment

Loner, funny, I was hitting the limiter on 1-2 shift too and THEN I installed it. Seems to only do it on this one on-ramp. Everywhere else it shifts at 5500, but this one it shifts at like 6xxx and bounces off the rev limiter once before it shifts...sigpic New 2010 project (click image)

I'll chime in on this one too.
After a more extensive drive with the modulator, it would seem that it holds the gears longer when under moderate acceleration (could be my imagination I suppose). While I haven't yet done a good WOT run, it wouldn't surprise me if I hit the limiter.
But I MAY need to turn it down, as it shifts much more aggressively than previously thought. The 1-2 is just crap-your-pants firm as opposed to before. Not that it bothers me mind you but I don't wanna max out the pump either.

on the 4t60e, the modulator doesnt controll shift timing at all, thats all done by the shift solonoids and pcm. all the modulator does is controll the pressure.

Hmm.....well I dunno whats happening then
I was under the impression that if the trans was seeing lower vacuum at the modulator, it would assume there is more throttle being applied, and thus holding the gears longer (like cruising 35mph and getting on it to pass someone)
Just proves how little I know about transmissions
.God help me with shimming those accumulators
