After I put the Transgo kit in my '88 Irocs 700r4, it shifts from 2nd gear almost right into overdrive. I drove the car for about 15 minutes and it didn't do it at first, but then it started doing it. I'll give Dana at ProBuilt a call, but just wondering if you guys had any ideas?

Any ideas?

 

Is this at part throttle or wide open throttle? What RPMs and Speed is your 1-2, 2-3 and 3-4 shifts occuring at?

 

It's at part throttle. Gear changes happen very fast, by 25-30 mph it feels like it's in overdrive. When adjusting the tv cable, the piece that slides back and forth with the teeth on it, is almost all the way back to the windshield in order to get the metal part of the cable nice and firm at wide open throttle. Does that sound right?

When you did the Throttle Valve, was the stock spring or the supplied red spring longer? Which one did you use? Did you use any washers? Did you install a boost valve? Which line bias spring did you use?

 

To be honest with you I'll have to pull out the transgo box and double check. I got it from Dana at Probuilt. What ever the instruction called for is what I followed.
