Trans power flush service - good or bad
It's been kind of quiet here lately so I figured I'd start a little friendly discussion regarding the transmission service fluid change using the power flush method. I know there are many opinions but I'll just write down that my dodge dealer (one of the largest in the west coast) recommends the flush. I know that the filter is not changed out but they recommended that the filter change be done the next service and besides the service writer (pretty knowledgeable and didn't try to up sell) said that the filter gets cleaned in the process (seems kind of BS to me). I had the complete fluid exchange done last Saturday. If anything goes wrong with the tranny, the lifetime warranty is still valid due to the selling dealer doing the work. Another thing, at 24k miles, the pan had a leak so they took the pan off and cleaned it out and replaced 8 quarts of fluid per the work order. Now at 40k miles, the complete flush and when I get to 60k, I'll do the service required filter change and trans service.

I think you would be hard pressed to actually find a "flush" machine any more. They used to reverse flush transmissions until it bacame apparent that was a bad idea. What they do is a fluid replacement and even if you drop the pan and change the filter you still need to hook it up to a machine or leave 2/3 of the old fluid in the trans.
I let the dealer do the service, so if they decide that they don't need to replace the filter - fine with me.

I had it done at 36K. It did not make any noticeable change in the shifting. It does however keep your warranty in affect if the tranny craps out. The transmission in my jeep went at 54K. I never got the flush done so the dealership was not going to repair it under warranty. They finally caved and fixed it. I just do not want to be in that position again. $2500.00 would have been a lot to pay out and no rental car either.

Big difference between FLUSH and a EXCHANGE. Dealer or independent I ask and go in to the bay where my vehicle is a meet tech,watch etc. I have sold and handled literary thousands of fliud EXCHANGES before I retired and use it on my own vehicles. Best thing to happen to a auto transmission since sliced bread. OLD fliud OUT. New fliud IN. Thats ALL it does. No harm to anything. I had lots of cutomers comment about improved shifting and smoother torque convertor lockup. All NEW fliud. It should if the old fliud is done in.

I've worked for 3 different dealerships, while it has been 10yrs, they all had fluid exchangers. So did the Valvoline and Quicklube my cousin has worked at. No powerflushers.
I have written a quick How'to that is a safe and very effective fluid exchange! The transmission pumps out the old fluid and you pour in the new. Non-invasive and no dangerous side-effects. DIY Trans Flush
While the filters are reccomended at 100kmi intervals, the best scenario is to drop the pan and change the filter out. Any new fluid poured in to push old fluid out will go through new screen. New fluid has no particles for the new screen so there's no concern there.

Letting the dealer do just the flush without filter change for $200 is reasonable since fluid alone is $115, but you do need to do the filter by the 2nd interval(100kmi)
Pretty sure it says so in the manual, I'd do it anyways because filters do clog and don't last forever regardles how often you flush your fluid.
Do what you like as it's your vehicle. Atleast your flushing the fluid where as others decide not to because they are afraid and simply wait for something to break...doh...

A chevy dealer that specializes in vettes does my vette for $129.95 and thats with Dexron 6 which is somewhat high dollar. The Dodge dealer near muy house is $100 bucks more. I take my Dodge and other cars to the tire store nearby. I bring the fliud and they charge me $35 bucks to hook them to a BG fliud exchange machine.

On my truck, the cost was $150 out the door, so I couldn't pass it up since the truck takes 17 quarts and uses at least 18 for the exchange. The price of the Chrysler ATF is like $8 a quart (18 x 8 = $144). The dealer had a $144.99 special going and since they use bulk ATF, they still made money. Another interesting thing about the Chrysler brand ATF, it says that it's a "life fill" right on the bottle.
