TH400 Part / Off Throttle Downshifts

[motormayhem]

I want to raise the part/off throttle downshift points on my M1009. When I am driving at ~15-30mph in a neighborhood it likes to bog in 2nd. If I show down for a turn or hill it stays in 2nd when I'd like it to drop down to first (without needing to floor it to hit the electronic kick down). Generally all the upshift points are reasonable (I'd be ok raising the part throttle upshifts a bit). Is it the governor weights or springs I need to mess with to raise the coast downshift points?

2 easy ways 1 is put in an adjustable vacuum modulator 2 adjust the vacuum at the VRV...I like to start at 12 inch pounds...check to see what you have. If you knock down the vacuum that'll make it hold and kick down easier...2a.....once you get close sometimes playing with the governor weights is the final button to push. Until you get the vacuum close, changing springs will make you go backwards.
