Default auto trans shift problem

simply put my 89 sometimes is not wanting to shift until 45 but i think it is rpm dependant. only intermintant(sp) did sound rough in od from 40 to 50 so left in d until now which it doesnt make a difference. valve sticking? torque convertor? ideas?

The governor may be sticking.

Service the trans (drop pan, replace filter and fluid) and top off with a quart of TransX. If its a valve or something similar sticking but its not to bad this should help. I've done it before and it worked for me. Look at it this way its a cheap thing to try before taking it somewhere.
