C6 automatic transmission filter change
 

Any one chaged out the A6 filter yet???? If you have how did you get the back 4 bolts out.

Thanks

No diyers out there??????

I don't think so!

Dealership did it for me.
:hide:

In order to get to some of the bolts, I believe we removed the (4) nuts "see green" then we placed a brace "see blue" and raised the trans a little.

I have searched here and asked questions on DIY A6 trans filter change and still can't seem to get a full understanding before I start.

- How do you get the back bolts out?

- Can you just measure the amount of fluid drained and put the same amount back in to avoid the need to pull plug after warming it up?

- Do you need a special squirt bottle/dispenser to get the fluid up to the fill hole?

- How much do I need and where is a good place to get Dexron VI without spending a fortune?

I though the A6 on my 2008 was a sealed unit and did not require service, it does not have a dip stick, am I wrong?

those pics are of a manual diff drain plugs.Not even an automatic which has a pan. PLEASE READ the original post!

MY advice which will save you a lot of money. Let the dealer do it. It is not an easy do it yourself! Trans must be level,right temp and fluid added when running to side plug until it starts to run out. If u are not up to all the facts and not done right an expensive repair due to an underfilled tranny will result. Leave it to the pros if your not mechanically knowledgable

Unless the fluid looks burnt, leave it alone. If it is burnt there are problems that a transmission shop needs to address. I have a truck with over a hundred thousand miles with the original transmission fluid, and no problems.

Agreed! I looked into this after I bought my car since I'm a DIY kind of guy. After reading the procedure and warnings, I decided to leave it to the pros when I have it done. This is not your typical automatic tranny with a dipstick under the hood and a drain pan on the underside. Do it wrong, and you've got real problems.

Manufactures prefer you not change out the filter by dropping the pan on newer model autos. They want you to get a fluid transfer done. They remove the current fluid in the transmission system, run a cleaning solution through it, and add new trans fluid back. There are some systems that are sealed. The sealed system should only by done by the dealership.

Our C6 Service Manual does not recommend or even mention any kind of fluid exchange or flush. The only procedure they show is the normal: drain-replace filter-refill.

Here's an old thread regarding changing fluid that has good info:

For the OP, PM thesubfloor, as he posted a how-to on removing the bolts, but I can't find it now.

To all the DIY'ers: I strongly suggest buying the GM service manuals for your specific car. They're not perfect and aren't necessarily the easiest read or method of repairs, but will give you a tremendous advantage over not having that reference available.

I have a shop manual and there is nothing in the book about removing the 4 nuts and raising the trans to get to the 4 bolts. All it said was remove the 18 bolts. The trans raise about 1' to 1 1/2" and you are able to remove the bolts. I was not changing the filter out just to do it. The Trans pan had a BIG dent in it. So it had to be replaced

Yep! That's just one of the many shortcomings of the manuals. Some stuff you just have to figure out on your own.

I particularly like the one for the removal of the freon hose connector from the compressor. See the illustration and then look at the car and see the impossible. :rofl:

The pic is not perfect, but it will work for a quick reference. We have replaced my 07 A6 filter many times before "every 20,000 to 30,000 miles" which has well over 120,000 miles on it. For those that wish to do the drain, drop pan, clean pan, replace filter, install pan, & refill; I would recommend you drain and refill the diff at the same time. :thumbs:

Three or four aft bolts can be removed with a 10MM ( I think ) open end wrench. Remove these bolts first and install them last. The remaining bolts are easy and follow info in post #14 regarding refill and torque specs. Filter pulls out and its not really necessary to change the applicable seal unless new filter does not fit ( unlikely ) firmly in place. The job is really no big deal, just rather messy. I installed about seven quarts ( a little overfilled ) but then when it gets up to specified temp all you have to do is remove pan plug to establish proper level. No need to add more fluid near those hot exhaust pipes.

Bolts must be removed and tranny raised. I watched my Corvette tech do it three weeks ago. Let the pro handle this one.

Same tech 21 years. Followed him to three dealerships - one of them 80 miles from my house. Yes, he's THAT good.
