What adjustments can i make to bring the 3rd to OD shift sooner. I can get it to shift when it reaches about 35mph by letting all the way out of throttle and it will upshift to OD. The way the engine sounds should be around 35mph - 40mph not 50mph.. Ive adjusted the TPS from 1.3 volts to .9 volts and checked every sensor i can think of.. Any help would be greatly apprieciated..
