Default 86 C4 1 -2 shift

Hello,
I have a 1986 with 74,000 miles. It has this thing where it needs to get to 2800 rpm to shift out of 1st gear. It also will not shift into 2nd under load, until you lift. Driving normal, I've gotten used to it. If you want to get after it, all you get is 1st gear. Which for around town is good enough, but I was wondering if there was a fix. Thanks for any input you may have.

Yes there is a fix. Your TV cable more than likely needs adjusting. Right now I would say that the governor is being overpowered. The governor and the TV cable work hand in hand to control shifts. Try this first. Now that I have posted, there should be another person along shortly to suggest an alternate cause.
