At the bottom of this description you will find compatible Mercedes chassis numbers. If you are unsure of fitment, just ask a question on this page and you will be answered shortly How Does It Work? Unlike most dipsticks, the 722.6 transmission dipsticks are a bit different. They are not designed to be left inside the transmission. They are only for checking fluid levels and then removing. This is a tool, not a replacement part. Simply insert the dipstick into the dipstick tube, remove, and check the fluid level like any other dipstick. This dipstick is marked with hot and cold readings for ease of use. Included with the product you will find detailed instructions with illustrations and diagrams.
Review: Very good tool for checking ATF levels - Used this on my C240 Mercedes ( with the 722.6 gearbox ) and it is very easy to use and very easy to interpret the ATF level reading. Comes with the red locking pin if you need to use it which I personally think you don't have to. ALWAYS check the fluid levels with the engine running, I made the mistake of checking with the engine off and it was giving me odd readings. Happy with the item and would recommend it if you want to check ATF levels on a Mercedes.
Review: This dipstick works great - The materials used in construction are first rate, and the dual ranges for 24 deg and 80 deg are very helpful.I didn't notice until I warmed her up but my MB water temp has a line marked 80 deg on it. Cool. Some people seem stressed about where the "stop" point is, but I would say just unlax there's a little reistance part way down but the endstop is obvious. I had noticed 1st time failure to shift in my 20yr old S500. Added 250cc at a time and it gobbled the whole quart of ATF 134, so another quart on the way. The rubber O ring and cap key are a plus. Without replacing the designed to break plastic red key it seems there would be an open airway into the innerds. BTW the little black cap comes off and on with a loud "click," It would be easy to push pretty hard, not hear that, and thinks it was back on...not.
