Thanks guys I appreciate the help.

Hi Everyone. We have a 2003 Fleetwood Bounder with the Workhorse chassis 8.1 Vortex V8 and 6 Speed Allison Transmission. When it kicks down from 6th to 5th at around 2500 RPM going to 3500RPM it is OK but then is changes again at about 3000 RPM into 4th and screams its head off at well over 4500RPM. Is there any way that I can get this altered to change down at 2000RPM which is more like where the max torque is on this big engine. Help would be appreciated. Garry.
