I noticed that driving today on the hwy that once up to speed and holding a steady speed that the truck kept up shifting and then down shifting. The speeds was about 100 kmph to about 110kmph.

Any suggestions on why or what I can do to fix this?

With a great signature like that I would have hoped for a year or trans

Assuming it's a 94 and a 47re (I could be way wrong, don't know if the 47re was made in 94 but...) the most common problems are battery grounds, engine grounds. Shifting from lock to unlocked correct? There is a black with brown tracer wire (memory issue could be different color) from the alternator to battery that I shielded with aluminum foil and electrical tape. That stopped my erratic shifting problems.

Good luck.

Sounds like 2500Ram is on the right track
Since your close to both BD and DTT, stop by one of their shops and pick up a noise filter

Heliarc, I went through all the cheap and easy fixes, ended up changing the TPS and solved the problem.

Easy enough way to help check is if it does it under a different throttle position, I.E. Shifts better at moderate accel and messes up under steady state, could mean there is a dead spot in the TPS.
