I have a rebuilt trans in my shadow with the basic part upgrades, clutches, steels, bands and whatnot. The car is used for ice racing on a oval track in the winter and may try it on the pavement this summer. The problem I'm having is getting the car to downshift earlier from second to first? I'm manually shifting the trans into 1st but it doesn't go until the RPM's drop. Is there a way to do this without going to a manual valve body? Right now when it downshifts the rpms are around 3500-4000. I'd like them to be up over 5 for more engine braking as the brakes start to fade towards the end of the race and that's in the middle of winter with snow and ice flying around for cooling.
