th350 trans shift problom

I swapt my 700r4 trans out of my 95 chevy shortbed and put in a th350 have probloms getting it to shift right up from 1st I did cheak the plastic govner gear it was bad will this keep it from shifting ?

Hello, yes the governor will prevent it from shifting. Another issue I see a lot on builds is the modulator line being too short and the use of too much rubber hose. The rubber hose will expand and contract causing erratic shifting. The factory uses a steel line with very short rubber hose to attach. Anyway, hope you get it fixed.
