Re: Transmission fluid check for 3.7
I use a 36 in zip tie also for my LX with the NAG1 transmission. Just put marks 5mm apart on the tie. I marked mine up to 40mm at 5mm intervals. The problem you'll have is getting an accurate fluid temperature reading, (I have a DashHawk on mine that reads the fluid temperature.) so you can get a true reading.
All this being said, I had my fluid level checked by the stealer when the vehicle was new (about 300 miles on it), and had not checked it since. My philosophy is that if it isn't putting anything on the ground, it's obviously not leaking. It is now time for me to do my 60K fluid/filter change (I do it more often than the book says), so I thought I'd check it before I do the changeout. Seems that, according to the chart, the fluid level has been overfull for almost 60K. The transmission has always, and continues to work flawlessly. My next problem is, when I change the fluid/filter, do I put the level back where it's been for nearly 60K or do I fill it per the chart?
For you, I would recommend you take it to the stealer this time, and then keep an eye on the floor and maybe periodically check it yourself with your zip tie dipstick. You may want to mark it right after they "bless" it so you'll have a reference point. Make sure the transmission is at operating temperature first......after about 30 miles of driving.
