I've noticed that the transmission will slip when the truck is not warmed up.  I'm not familiar with auto transmissions.  Is this a problem that a fluid and filter change would help, or is it just because it has 116K miles and I should just live with it?

Thanks

How many thousands of miles since the tranmission oil was changed or even checked?

I bought the truck a couple months ago and it currently has 116K miles.  I have no idea about the last trans fluid change.  Is this a typical symptom of old trans fluid?

I can probably get the fluid changes at a oil & lube place.  Is there a filter that nees to be replaced, or is it a screen that needs to be cleaned?

Thanks

Some automatics do not shift as well with cold oil. The torque converter may be draining slowly with hot oil when parked and slow to refill with cold oil.

...  I would recommend doing the '30,000' mile service and changing the transmission fluid. My ‘99 V-6 4x4 automatic transmission only had a window screen style filter and a simple clean-out of it would be sufficient. The simple drain and re fill only changes about 5 quarts so some people change it a second time after a 1,000 more miles. Remember it’s the additives that wear out even if the transmission has not been over heated or abused.

... It is fairly easy to do yourself. Measure all that was drained and refill with the same amount. Then after running it to heat the oil for expansion check and add  more as needed. When reinstalling a steel oil pan make sure the bolt holes are level with the lip and not dimpled. I do not trust the 'lube places' to do the work on my vehicles. Most do not pay enough to get qualified help.

The Amsoil website has instructions on how to do a complete oil change.
