Trans Slippage Question
Can the trans shift good at all times but slip in overdrive?
I don't notice anything unusual but on hills it seems to slow down at steady RPM's.
Or is something else going on?
Thanks,

It's tough to answer that without any details about the truck.

It shifts fine, but seems to slip in overdrive.
Yes I did drain the convertor.
No ugly stuff in the pan.
Wondering if there was something that controlled converter lock-up.

Or something else that could be wrong.
I didn't notice it till after changing the fluid.

did you use correct fluid? what brand?
is it full when you check it warmed up?
was filter installed with o-ring and pushed up correctly?
try resetting the computer.
is the button on shifter working correctly?

Trans Filter installed with o-ring and pushed all the way in, original filter fell out in the pan.
Computer was reset when trans fliud was changed, I put a new o-sensor in at same time.
Push button works and light doesn't flash.
I just chcked the fluid, it is approx a 1/4" little over full.
