That's a sign of tranny trouble. Have the truck scanned for codes, and keep your fingers crossed.

Possibly the speed sensor on top of the rear differential is going out or there is a bad connection.

I am experiencing same problem. Dealer said the hard shifting is due to a boost in hyd. pressure to insure that bands etc are well lubed and cooled. I had it de-coded and will have a friend replace the pump and torque converter.
Good luck!

Have no freinds that can do the work. Dealer wants $500 to open it up and tell me whats wrong. I`m in the wrong business.!!! They say its a six hour R&R, many if you use only one hand. Thanks for the input. Bill

THANK YOU FOR YOUR REPLY. HERE`S THE LATEST. THE CODE IS P1728, AND THE DEALER WANTS $2.500.00 FOR A REBUILD. I THINK THAT`S REAL HIGH. I`M LOOKING SOMEWHERE ELSE

Check your shift solenoids. I had the same problems which led to a complete replacement of the trans. under warranty thank god...It died at 34K and was replaced, haven't had any issues sense. (knock on wood!!!)

I would definitely start by replacing the VSS(vehicle speed sensor) on the rear differental. It is a simple 10 min job( search this form for instructions). My '99 was doing the same thing and that was all it took to fix it. Will save you about $2,470.00 if that is all that is wrong. Does the speedometer not work some of the time? That's also a sign that the VSS is going out. Hope this helps and most of all saves you lots of MONEY!

I wouldn't recommend an additive, if you are using an approved oil you don't need one. I use the Rotella Synthetic personally, but regular Rotella or Delo 15w40 are very popular.
