If thats the case, then why did you buy the sixty-some dollar part? I thought I read on here the 06 dipstick is some 15 bucks or less. I'm just curious as to why there is some "special tool" for the dealers if everything is the same. SOMETHING must have changed for them to order a new part, rather than use a standard dipstick, but from what I've seen, my trans filler is in the same spot as the girlfriend's 06.

The service department told me that the new universal measuring tool is a more accurate way to measure the fluid level. There are too many Liberty’s rolling into the dealership with too much added fluid because more and more people are having a hard time understanding how to check and read a dip stick.

With the longer 60,000 mile trany intervals (Schedule B), and a much longer mile trany interval (Schedule A), there is really no reason to check the transmission fluid if you regularly have your KJ inspected and maintained. Plus there are many makes and models who are using the 42RLE besides our KJ. In my scenario, I had the trany cracked open at 1,700 miles for the installation of a shift kit.

There was approximately 5 quarts of trany fluid lost that I later topped off with AMSOIL. I plan to change the trany fluid completely over to Amsoil at 20,000 miles. I figured the “measuring tool” might be a little more accurate, and I wasn’t sure that the previous dip sticks would fit the same (the '07 has a plug that threads on). So to finish answering your question, I figured the special tool would be nice to have. It rolls up nicely and fits in my Tool/Supply Box that I keep in the Jeep at all times. It cost more, but it’s what I wanted.
