I drained and replaced 5 quarts myself at 40k, and am planning to do the same at 50k and 60k. I believe that is better than waiting to have the dealer do a complete change at 60k.

drain diy!

 

Exactly what Ive been doing! Ive done 2 drain and fills and I'm a little under 60k. I think I will be doing another drain and fill on the next oil change. This way the ATF never gets to sludge and get too dirty.

 

i did mine at around 45k miles myself. 12quarts at $11 a piece.
-unhooked the cooler line going to the radiator
-put it in a 15qt bucket
-started it
-poured in the fluid one after another into the tranny dipstick hole
-turned off the car at the 12qaurt mark in the bucket

fluid gradually went from the brown dingy look back to pinkish


I would like to do it again at 60k miles which might be another year from now

 

The dealer I go to uses a machine similar to the BG machine and the cost is something like $280. I asked them why don't they do it per the FSM. Their response was they've used this machine all this time and they haven't had a problem.

So I think I'm going to do myself, buy the 15 qts of S-Matic fluid and do it per the FSM. May also record it on a video camera so I have it on record.

 

i have a everwear flush machine at my shop but does it have a drain and fill hole? never did look to see what type of diff fluid the G uses
