I am in the process of doing fluid changes, the truck has 234k and i have no idea on previous maintenance. I haven't had the truck long. I have heard not to adust the bands or do it every fluid change. What would y'all recommend?

Adjust bands everytime you drop fluid. You are not suppose to flush it if you have never done it before or on a regular basis. I would suggest doing govenor pressure sensor /transducer and govenor pressure solenoid.

I've though about that, do you know a good place to buy them and do you know how to test the stall speed of the TC

Cascade transmission parts

I do believe stall speed can be tested by power stalling and the rpms it holds at is the stall speed

Mopartech is right. Just chalk the wheels, Set the park brake, and hold the brakes with all you got, then put her in gear and rev it up. Whatever rpm the engine reaches and you cant get it to rev any higher is the stall speed. This is also a very good test to do to figure out the condition of the tranny. If I ever look at buying an automatic transmission vehicle, I do this test. You can tell real quick if something is slipping in the drivetrain.

Click on the link and scroll down to "change the automatictransmission fluid"

It is  more thorough than simply dropping the pan, where you will only get about 25% of the total fluid.

Thank you for the info. I read that the factory stall for these truck are around 2k, does that sound about right?

That sounds about right.

TC seems to stalls around 1200, i dont have the wheel chocks but with e brake set and brake pedal mash it feel like its trying to move. RPM`s didn't get over that, also didn't hold the throttle done for more than 5 sec`s or so.

I replace the solenoids, ajdusted the bands and change filter and fluid. I redid the stall test and got the rpms up to 1800. I wad a little timid with it before.
