Chevorlet S-10 pick-up

Customer Question

i have a 1995 s-10 chevy pick-up with a 4.3 v-6, automatic transmission that was rebuilt about 4 months ago, it shifts fine till it warms up then it stops shifting, it seems to stay in 3rd gear unless you shift down manually

does it ever shift into fourth?
Customer: replied 1 year ago.

yes before it warms up, yesterday i drove it for about 20 miles and it shifted fine and then it stopped shifting. you can manually shift down and then as you speed up it will only shift up one time, i'm thinking between 2nd and 3rd
