How does the dealer flush the transmission. How do they drain the torque converter. Also there is a shutter from 3rd to 4th it seems like it does not have enough pressure to stay in 4th. Also my dads 95 ford Grand marque does the same thing what do you think this is. Thanks

They hook up the trans to a machine designed specifically for the job and yes, it does replace the fluid in the torque converter. After the flush, they then drop the pan and change out the filter and remaining fluid. This made a huge difference on my 5.2 automatic. I just had it done at 60,000 miles.

How do they flush it out, through the transmission cooling lines with compressed air? THanks

They use the trans lines but flush it with fresh fluid until all the old stuff is out which is the best way.

One way you can flush all the fluid yourself is to unhook the line that feeds atf from the tranny to the cooler, put a flexible hose extension on it and put that hose in a bucket. Next make sure you have a few spare quarts of atf and put a funnel in the tranny fill tube. Start the engine and let it idle. The transmission pump will start to pump out the fluid. Here is where the spare atf comes in. Pour the extra atf in to the tranny at about the same rate it is being pumped out. Once the fluid coming out of the transmission is clean you can turn off the engine. Now drop the pan and change the filter. Button everything back up and fill with the appropriate amount of fluid.
I've done this before and it works pretty good. Saves the cost of the service by the dealer, etc..

I went into Jiffy Lube yesterday to have this done on mine and for some reason they were unable to do this. Has anyone else had this problem with Jiffy Lube? or anyone for that matter? Also, what does it cost to have done at the dealership?
Thanks,

Did they say why they werent able to flush it?
I had the same problem at a shop near me. Later I found out that there is a check valve in the cooler line that they were connecting to..... they had to connect to the OTHER line.

I would just HATE to burn up something by not pouring in enough or something. Dealer cost was about $220 which included the fluid and filter. It was well worth it to me, but I admit, I am on no budget.

If you service your tranny at regular service intervals you should not need to flush it. I do disagree with DC a little about when you should service a tranny thought. If you tow alot or race your truck you should do it change the fluid and filter every 15,000 miles and if you drive easy then you should service the tranny ever 20,000-24,000 miles. I also think that Redline C+ATF is the best thing that you can do for your transmission. Did you guys know that the 45REF tranny has two filters in it. The primary one is oblong and shaped kind of like a flattened football. The secondary filtary looks like a small spin in oil filter and is in the tranny on the return side of the cooler line.

If you pay attention you won't have to worry about burning anything up. The fluid at an idle comes out relatively slow. Definately slow enough for you to keep up with it by dumping fluid in. $200 is a lot of money for a service that you can do yourself for probably under $100 (I'm not sure how much the filters are as I only have 2500 miles on my truck so far)
As a side note, this trick was taught to me by a mechanic that has been working at dealerships for 25 years....
In the end though it's all up to you and how much money you have to burn.

I respect anyone who has the confidence to do that job yourselves. I have been a Harley mechanic for more than 30 years, but these complex auto trans have my respect. I leave those to the pros. I am lucky to have an excellent dealer here in Georgia.
I have heard that Redline and Amsoil both make excellent fluids for the Daks, I am sure they would do fine.
The fluid change is more a hassle to me and its easier for me to simply earn the $ than bother with it myself. MOPAR to you friends!

No they didn't say why. I watched and they were able to get a little fluid, but not like it was supposed to. Then they said that you just can't do that with some Dodges.
Oh and they were only going to charge me $79. They don't change the filter, just flush it. Do the filters cost that much, or is there something else that the dealership does to warrant the extra $?
Thanks,
Jason

I could get the flush done for $149, or the filter and pan for $79, best way is both which is what I did. That price also included changing the filter.

You can buy a filter and pan gasket kit for about $13 from Autozone..... Fluid costs about 2.35 a quart..... my trans takes about 5 quarts per change...

The transmission including the torque converter holds nearly 14 quarts. I you only change what comes out of the pan, you will simply be mixing old and new fluid. It would be like changing your oil without changing your filter, (to me).

I doubt that it would be cost effective or nessary to flush a tranny every 30,000. Remember guys that there are no combustion byproducts to contend with in trany fluid. The only thing that should show up in tranny fluid is clutch friction meterial and some aluminum and steel particals. Your filter should filter all of these out. So the only reason to change fluid is to stay ahead of oxidation. You should always change fluid long before it ever shows signs of oxidation. If you weight for it to smell burnt or change colors then it is too late. Then you should have it proffesionaly flushed. You should always change your filter/filters when you change fluids. I always like to change my filter/filters before I hit 10,000 miles the first time and get 4-6 quarts of Synthetic trany fluid(REDLINE C+ ATF)in it. After that I try to do it every 20,000-24,000. If I am towing alot or driveing very agresively from stop light to stop light then I up it to 15,000 miles.

I understand your point sandman. My own feeling is just that even $200 for a fluid flush and filter change is cheap compared to a new tranny so I sleep better knowing that it has been done. Again, just my personal feeling.

Rascal, Nothing wrong with that. Do you get it flushed every 30,000? Check this out. I am still looking for an after market alternative for these. The trany return cooler filter if $16.00 at dealership #04799662, the primary filter is $37.99 at dealer, and Mopar ATF+4 is $8.99 a quart. They do not have a gasket just RTV sealant.
I am getting Synthetic Redline C+ATF for $7.35 a quart.
I am sure that by the next time I change my fluid Baldwin or Hastings will have these filters but so far they do not have the right one. Baldwin gave me the wrong filter number for the 45 REF tranny's primary filter. I am going to give it to my friend for her Dodge Ram. P.S. If you take the price that the dealer is chargeing you for a part and divide it by 2 then you can usualy get close to what they are paying for it from Dodge.

Makes very good sense sandman. I just got my Dak and it had 60k miles on it. I got it from my brother-in-law who passed away in May. My sister gave me the car to keep it in the family, so I have an edge in the $ department already. I plan to maintain it per the factory chart, so Yes, I will flush it each 30k.
Good Luck,
Rascal
