Won't kick down?----from stepping on the gas more? It should come out of OD relatively easily---like not much more than 50% throttle. Perhaps less depending on vehicle speed. What does this trans consist of? Is this a stock trans? Is the cable tight enough?

Your cable is definitely out of adjustment. Should kick out of OD pretty easily, like on a hill etc., Like the post above said 45-55% and it should go to third from OD. I would have someone operate the throttle and see what is going at the trans. I doubt you are seeing much to any movement of the lever at the trans even if the cable is moving. It could be hooked to the wrong hole in the throttle lever at the carb. Are you using a Lokar or similar cable? Send some photos if you could so I can see how they hooked your trans cable. It sounds like they didn't take it for a shakedown run when they did the install which is kind of a no no as a technician.

Tightened the cable up more at Royal Farms when I got gas and after that it kicked down going a low speed, I will inform you of what happens tomorrow. Also I got 15mpg

Good. Glad to hear you got her kicking down. If you get it in top gear for an extended cruising period of time you will probably notice even better mpg. That situation alone is just one more reason to be glad you have the constant pressure VB. I may take a little touch and go.

Yeah I think I have to loosen it a little because it's shifting into overdrive at about 55-60.

That's not too far out. I think my '90 was around 55 and my '88 was about 50. But the '88 was a little lower geared.

Oh alright, she's parked for right now as I realized that I didn't have brake lights tonight, measured and had voltage at the brake light switch and replaced it. Tomorrow I will do a couple things to check if it's the turn signal switch... again.

Mark... The Super Coupe slip yoke measures about 3 5/8" between the universal clips. Is there a universal which can adapt the 3 1/4" driveshaft to the 3 5/8" slip yoke? Would you recommend a setup like this or should I just buy a 3 1/4" slip yoke?
