Check the adjustment on the band. 10lb ft. and backoff 1 3/4. Most likely loose.

Yes. If that helped, you might want to check the low-rev. band too. Same thing, 10ft lbs but back out 3 turns. Sounds like a rebuild is due soon, sorry!

Not to bear sad tidings but it could be the intermediate band and clutches are at end of life, or the Governor or intermediate servo are sticking. The later two are easy to do with the trans in the car. The bands clutches are not. Don't forget to drain the torque converter too. Type F should be used if that's what you've been running.
