Hi guys, I have a 86 montecarlo ss that has ZZ4 350 motor and a 200r4 trans. When driven at light loads and part throttle the car shifts nice. When I manually shift through the gears the car pulls hard and the engine revs to 5600 rpms. But when I put the car in OD and floor it the car shifts at around 3500 rpms. I have messed around with the TV trans cable a little but can’t find a happy medium for normal driving vs gassing it. So what can I do to make the rpms run out when the car is place in OD and have it feel the same as when I manually go through the gears? Do I need to mess with the trans governer or something else?
