tranny drain and fill question...

[Matt]

I wanna do this but I got the v6 with the sealed Mercedes tranny any tips

You can use a fluid evacuator to suck the fluid out through the dipstick tube and then refill with the same amount you pulled out.

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.

[Matt]

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.

Sounds like a lot of work. Glad I don't have the Nag1

Matt, how much does a fluid extractor cost? If I used one does the fluid have to be cold when extracting?

This is the one I use (just under $100): http://www.amazon.com/Mityvac-7201-F...luid+evacuator

There's a cheaper version that doesn't have the reverse flow valve that runs around $60-70.

Due to the mileage when you purchased your Jeep, Im willing to bet that the trans service was never done. If I recall correctly the 1st trans service is right at 75,000 miles. So if it were me, I would definitely do the filter/fluid swap soon.
