I am planning on doing multiple cycles of the drain and fill on my 5AT rather than a flush at the dealer. It wasn't clear from the other threads but where do you fill the transmission with the new fluid? Dip stick area? Also, how many quarts of the S matic are required for the fill? Other than warming up the car, any other instructions or tips other than just drain and fill?

Thanks.

The 5AT is a little different than the current 7AT, you CAN fill thru the dipstick in the 5, the 7 has no dipstick so the fill is more work.
Here's a couple links, the first is a 5 the second the 7. Be sure to use Matic S fluid. The second DIY removes the pan, that's what I did and I'd recommend it, nice to get the magnets and pan cleaned up while you're there
Read this entire thread, there's some helpful links posted toward the end~

Blnewt, thanks (as always) for the helpful links and for your response.

I checked the transmission fluid with the dipstick for the first time on my car with 50K miles and it still looks pink, almost like new fluid. I'm now reconsidering whether I should drive it another 10K or longer before changing it.

I've recently changed the coolant and differential fluid and those looked pretty clean as well. I do realize the protective qualities of these fluids can't be determined just visually.

IIRC they officially recommend the service on the 5AT @ 60k so if so, then another 10k miles should be alright.
