the fluid is fine i changed it just the other day and the fluid and filter was fine no burned fluid and excess shavings. all looked good.

I am having the same problem with my 98 I was told that larger tires caused it and there is no fix other than to remove the tires and go back to stock these are only 9.30s so thay are not thqt much bigger but it acts up in drive at around 45-50 mph and smooths out at 60 def can feel it and see it jumping in and out of overdrive on the tach tach stays steady when the truck is in drive 3 and not allowed to use over drive got any ideas for a fix?
