Is it possible to get a th 400 to shift (manually) at a higher rpm at WOT without going into the governor? If I unplug the vacuum line to the module can I shift it manually at a higher rpm, if so will it hurt the transmission? The tranny shifts out of low gear at 5000 rpm's and I want to shift at 5800-6000.

The governor is relatively simple to mod.

No way to really increase the WOT without modding the governor.

With the modulator vacuum unplugged it will shift like it was at WOT all the time. The vacuum modulator adjusts part throttle shift points. Light throttle=high vacuum=low shift points. WOT=low vacuum=high shift points. The governor controls max shift rpms.

Thanks guys, it looks like i'll have to go into the governor to achive the higher shift points.
