Transmission Fluid Change.

Anyone know if it is possible to change the transmission fluid
on your own?

Also a brief summary of the procedure would be great.

Thanks!

Re: Transmission Fluid Change.

I know this is pretty weak, but here's the info from the SI database:

Transmission Fluid Replacement




Preliminary Procedure
Raise the vehicle. Refer to Lifting and Jacking the Vehicle.

1
Fluid Drain Plug

Caution: Refer to Fastener Caution in the Preface section.

Tip
Place a drain pan capable of containing more than 5 quarts of fluid under the transmission before removing the plug to drain the fluid.

Tighten
12 Nm (106 lb in)

2
Fluid Level Indicator

Tip

Transmission will require approximately 5 quarts of fluid.

Fill the transmission with fluid. Refer to Transmission Fluid Check.

Re: Transmission Fluid Change.

Is there a filter that needs replacing, or anything other than just changing the fluid?

Thanks BTW.

I have done a few fluid changes; I usually head over to the local parts store and buy a kit for the tranny. Most vehicles come with a new seal and filter; exception my Taurus has a permanent seal so I swap out the filter only

Re: Transmission Fluid Change.

There is not a serviceable filter on our transmissions. I don't think there is even a traditional pan to drop either. I'm planning on changing the fluid in mine this weekend though. The procedure above shows that 5 quarts is needed for a drain and refill. The total capacity from what I found is 9.5 quarts, so a single drain and fill will change out 50% of the transmission fluid.

Re: Transmission Fluid Change.

If there is no pan drop; then I guess you would need to have it serviced at the dealer to remove all the fluid; I guess 50% is better than nothing if you're going to do it yourself

Re: Transmission Fluid Change.

How much ($) is the recommended tranny fluid / quart?

In most ATs you only get a portion of the fluid out if you just drain the box... The dealer can perform a flush which circulates out the old and in with the new. Not sure what the cost is for the the acadia but my Silverado was not too bad maybe $100? Don't remember exactly, I had a bunch of stuff (radiator flush, tire rotation, differential service)done at that time and the total was about $300.

Re: Transmission Fluid Change.

My dealer quoted me about $130 for the complete flush with Dexron VI, in which they disconnect the transmission fluid lines running to the cooler/radiator and use a pump to remove all the old stuff and pump in new stuff.&#160; However, I've heard stories of this stirring up debris/wear particles and essentially plugging the non-serviceable strainer/filter and causing a transmission failure.

I don't know if it was coincidence or not, but this exact thing happend to our Odyssey when we had the flush thing done at about 65K miles.&#160; About 2,000 miles later the transmission failed (replacement was covered under our extended warranty).&#160; Now, the Odysseys had transmission design problems to begin with, but its kinda hard to completely dismiss the connection.

As a result of this, I've pretty much sworn off the flush procedure and am going to stick with the good, old-fashioned drain and refill.&#160; I'll take some pics too if everyone wants to wait till the weekend.&#160; &#160; The Dexron VI was around $6/quart, IIRC, maybe a little less (I don't have the receipt with me).&#160; I need to do my Silverado too, but it has a pan to drop and has a serviceable filter.

EDIT: Trans fluid was $4.70/quart
