Trans flush and refill?

[Reek09]

I'm contemplating on having the fluid in my trans flushed and refilled via lube it with their T Tech service. Although a few mechanics have told me, if the trans is shifting fine, leave it alone. My Rauder has a little over 107k on it. Any suggestions fellas?

Get it done, just make sure they use the correct fluid, Mercon V.

If your fluid is not all burnt and smelly, definitely get it flushed now before it becomes that way.

Most places won't flush a trans with over 75k miles IF they don't know the service history on it. If anything I would at least drop the pan and change the filter, then just top off the fluid to full.

If you can do some of your own work, buy a trans pan with a drain plug in it and then drain/refill your trans fluid every 15-20k miles after the filter is changed.

+1 on drop the pan. You can have a ford dealer do a pan drop - new transmission filter and clean the magnet off. With a fluid transfusion you are still running a dirty old filter and magnet. I say do both if you can.

Got the trans flushed in the vic at 128k, fixed the TC shuddering issue and shifts better. My tranny was rebuilt and I'm pretty sure they just dumped regular ATF in there, which is why the TC was pissed off.

Just had mine done right at the 100,000 mile mark a couple weeks ago

I'll only trust a F/L/M dealership to do any flushes on mine.

Disconnect cooler return line from trans, add 4 feet of extension hose, put in a 5 gallon bucket that you marked off graduations with a sharpie marker, and start car and add fluid at the same rate it's removed, until you have run 13 quarts through the system. You have now performed a 100% flush of the volume of the whole system. Ta-da.

Buy an E-350 pan with plug so you can drain it yourself every every 25K or so without having to drop the pan.

I agree with the pan drop especially if the fluid still looks good. Once you look at the dirty magnet, you know the pan drop is the way to go.
Do a search for my other posts with the photos of the magnet inside my Marauder's trans pan.

This method works great. I've used it on my explorer.

My filter has 72k on it though so I'm going to swap the filter and that fluid then do this method at 100k.
