Anyone had any trouble with the transmission kinda hesitating or shuttering when backing up? Truck is an 04 with 46K on it. Fluid level is good. Truck is out of warranty of course, so I didn't know if you guys had any idea before I take it in to have it looked at.

 

I'd probably get the fluid changed.

 

If it's that bad , you might want to get a fluid transfer. I can't recall what the proper procedure is called ? Some one else will have to chime in for that, but they just hook it up to a machine and transfer your old fluid for new.

It's not called a flush - That's a little different and I wouldn't go that route.

 

It *might* be a dragging E-brake.

The term you are looking for is "fluid exchange". A lot of people call this a "flush" but that's not really correct.

 

Thanks for your input, A fluid change is definitly in order. Any ideas on a place to find how to do the fluid exchange myself?

Just a thought, but why couldn't you put all the clean trans fluid in one bucket plus a couple extra quarts for good measure and the drain hose in another and start it and run it until all the clean fluid has been taken in. Reconnect everything, check your level, and your done. Instead of starting and stopping the engine several times. That is what the T-tech trans fluid exchange machine basically does or am I missing something here.

Wait a minute. I was just thinking it through and I guess there wouldn't be any suction to take the new fluid in as the pump would only be working to push the fluid out and because the line ends in a bucket there is no pressure to return it. It that correct?

 

Bingo! You are a winner. There is no suction in the cooler lines to pull the new fluid in.

The T-Tech machine sends the old fluid into a chamber with a piston the separates it from new fluid on the other side. As one side fills up with old fluid the piston is forced over, pushing the new fluid into the cooler line.
