I had the local Valvoline Lube Center do this for me. COSTS money, but no fuss/no muss on MY part, and I'm good to the 125,000 mile mark on mine now! :cool:

All ATF+4 is synthetic. I would stick with the recommended change interval at the very least. 30k for transmission is a good interval.
I will probably service my transmission in the next couple weeks. I did it at 75,000 like the owners manual says and im now at 118,000 miles. My fluid still looks brand new but I know it could use a swap.
I wanna do this but I got the v6 with the sealed Mercedes tranny any tips

Yea take it to the dealer. Lol
yeah ive wondered about that too
There is a dipstick you can buy. Then what you'd want to do is check the fluid level when the vehicle is cold and score the dipstick for your "cold" mark, and then check again when its hot and score the dipstick for your "hot" mark. Then you can drop the pan, change filters, etc and use that dipstick to get your fluid level back to where it was without having to hook up a scanner to read trans temp.
Here are some dipstick options for the NAG1:
If you have a scanner that can read trans temp, this works well but is $60
Special tool 9336
If you can't read trans temp, go with the cheaper option jeep p/n 53013592AC ($12 from wholesale mopar).
Either way you can mark the cold/hot fill levels like I previously mentioned. If you use the 9336 tool then all you have to do is get the fill height to correlate with the trans temp (assuming you have a scanner than can read trans temp). Or if you use the cheaper Jeep dipstick, this chart can be used to correlate fluid level to temp.
