A fresh trans filter and fluid change is always a good thing.

You can do your own flush at home if you unhook the cooler pressure line from the transmission. Best way is to unhook it from the trans, and adapt it with a nipple and rubber hose. You then start the truck, let the trans pump fluid out, refill, repeat. It take a good amount of fluid to do this but that is the easiest way to DIY flush the fluid.

Good tip on that is, on the driver side of the transmission is a "line pressure tap". It is easier to get to than the cooler lines. You can unscrew the tap, screw in a nipple and attach a hose and crank it up. Line pressure will pump out the old as you pour in the new. Takes usually about 20 quarts to look brand new.

I forgot about that. It's the same one that you typically install the temp sender in correct?
