The truth about transmissions

I have about 145k on my truck. I pull up to about 6k every now and then, and when I'm not pullin I do admit I get on the truck a lot. Its chipped and all that good stuff. I bought the truck used and dont know if the fluid in the trans has ever been changed. A few months ago I put a tru cool in line with my factory cooler and the old fluid did have a burnt smell to it but it looked clean and red. I'm looking for advice about getting the transmission flushed. I've heard its bad because it shakes up all the metal and stuff in the pan and causes damage. Would I be better off just draining it then refilling it? TIA

Dropping the pan only removes less than half the total fluid. Adding new fluid to it simply mix old with new.

Would you empty half of your engine oil and fill it up with new oil? you would not do that with your engine, why would you want to do that with your trannie?

If your truck is a '99, 2000, or early 2001, it should have a drain on the torque converter. rotate that bad boy so the drain plug is at 6 o'clock and drain away. drop the pan too and replace the filter. No flush necessary. good luck.

That is interesting. What do you mean by "rotating that bad boy" ?

A picture of that torque converter drain would greatly help.

You just need to block your wheels so your truck doesn't move, take off the protective shield covering your torque converter, place your truck in neutral, and then rotate the flywheel until you see the torque converter drain plug. Rotate it until it is straight down and accessible. It is really easy. My 2001 w/ the V10 had the drain plug. I was a little upset when I found out my 2002 Powerstroke didn't have it after rotating the torque converter around and around only to find no plug.

It is just a few bolts to take off. Easily accessible. You will see once you crawl under there.

Do you really think that emptying your engine oil through the drain plug removes ALL of the engine oil?
