I have a tpi 350,ford 3.55 gear,700r with transgo shiftkit.The trans has 3000
miles on it.Everything was working find untill I had the corvet governor changed to a standard v8 governor for better gas mileage.Now It shiftes fine but will not diwn shiftt at all. Install a tv cable correction spring.It will bark the tire in second and third.Under normal operation it shifts into forth between 35 and 40 mph.How does the governor controle downshift.

Thanks

 

It will downshift when slowing, to a stop,butwill not downshift in any gear at wot
