Transmission flush

I’ve been researching for days about having the A750F in my 2011 flushed with a machine and cannot find anything conclusive whatsoever.

So here goes: I bought the truck in 2016 with 85k, one owner, dealer maintained. I recently hit 150k and decided it’s time to replace all my fluids. I want to have the transmission flushed by a shop, but it seems like most people are opposed to this, and nobody has offered experience or results after having their trans flushed. I understand the concept of wear material in the transmission allowing everything to mate up properly in order for the trans to function. I don’t tow, I don’t beat on the truck, and I’ve never had a single issue with the transmission. I’m not interested in the fluid exchange method, way too much headache IMO. So what’s the deal with the flush? Has anyone had it done? Should I be worried? Any feedback is appreciated.

 

I had the dealership change the transmission fluid at 50,000 miles in my 2011,
I'm not sure if they did a total flush with a machine or if it was just a drain and refill
if I remember correctly it cost around $140.00

 

Every 2-3 years I just drain the pan and replace. This ensures theres always enough fresh oil and additives in the trans fluid for proper function. A full flush really isn't necessary.

 

When you use a flush machine you are forcing fluid in and then sucking it out. By forcing this pressure it can dislodge alot of clutch and normal wear material that is inside the torque converter and transmission, So yes the fluid after may look nice and red but you can cause some debris to start floating around and get suck inside the valve body or solenoids. We usually do it as a last resort effort on a transmission and advise the customer of what the outcome may be. Almost every manufacturer if not all recommend not doing flushes .
