Early design 700 tranny will upshift to 2nd gear while the shifter is in 1st.

You can do 1 of 2 things;

Install a larger low/reverse boost valve (.296 diameter)... or install a TransGo shift kit...

700- 2 & 3 kit , will over ride the command to upshift from 1st to 2nd gear while the shifter is in 1st gear.

IF you have a late 1987 & newer 700 tranny, perhaps the shifter adjustment is out or your tranny builder did something I am not thinking of at the moment. Could be mismatched parts
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
