At what rpm can I expect it to shift if I run it and just leave it in drive? My peak HP is at 5600 on the dyno. I'm going to assume that your T/A valve body is NOT a manual shift valve body so there is no way for anyone other than a tech at T/A to know what your throttle pressure is set at Without knowing the actual throtte pressures at WOT who knows what RPM it will shift at I use to shift my pump gas 518 C.I. low deck stroker motor with the six pak on it at or above 7000 RPM because that car ran faster than shifting it at or around 5000 to 6000 RPM My motor made peak HP at 5600 when it had ported iron 906 heads on it and it made peak HP at 5800 RPM with the CNC ported Eddy RPM heads on it Both combinations like being shifted a lot higher than what it made peak power on the engine dyno at Take it to the track and try shifting it at different RPM, 5000, 5500, 6000 and then 6500 RPM, see what the motor likes and use that If it fastest at 6500 RPM try 7000 and then 7500, if it is still pulling hard at that RPM Mr.Cab Racing and winning with Mopars since 1964.

I changed plugs and ended up just shifting the column shift manually and it wasn't too scary! I was worried about mis-shifting...
