I wouldn't recommend a transmission flush, but you could safely do an ATF drain & refill regiment. :wink:

Also check the ATF filter. I've read where engine oil filters have been installed. Engine oil filters are too restrictive & can cause issues.

► Edit - Your "Public Profile" says '06 XT, but your post prefix shows '09-'13 & those years don't have an external ATF filter.

That is what I would recommend too. You could do it at the same time of regular oil changes.

@djnauticz - There are threads already on how to do a trans fluid change - Get several crush washers and drain out the fluid (just shy of a gallon) and refill with the same amount. It will take 2 or 3 times before the fluid is all exchanged because you can't (and shouldn't) get the fluid out of the torque converter by draining.

Put some miles on it between each drain to give the new fluid a chance to work through.
Each time you drain it, what comes out looks more and more like trans fluid.
By the second third time the fluid will look new and after the third, it will be.

I'd suggest you buy the fluid in bulk to save some money - You'll need 3 gallons.

It would be a lot of work, as you'd have to drop the pan to get to it. It's basically just a mesh screen to catch the large debris.

Have you done a drain & refill regiment to see if that helps with your shifting issues? :confused:

Nope...this will be my first tranny oil change.
Was looking to drop the pan, check the strainer, cables and solenoids. Also check the magnet for large particles.
