Saihisday Transmission Fluid Dipstick Replacement for Mercedes Benz Transmission Oil Level Dipstick Tool 722.6 917-321 140589152100 Transmission Fluid Level Dipstick

I bought this dipstick to check the the transmission fluid in my buddy's Mercedes and it worked perfectly. It is the correct fit and length and easy to use. Definitely accurate and essy to use. Great price for a durable dip stick!

Works well, good quality

Do you drive an older Mercedes ML? Can you point out the transmission fluid dipstick under your hood? If you have the first ML series W163 or the second generation series W164, you’ve likely wondered why you can’t find that elusive creature. I know I certainly did! I ordered the SAIHISDAY Transmission Fluid Dipstick to assist with determining fluid level following a transmission service. I’m really glad I did. The engineers over at ZF Friedrichshafen AG (ZF) that designed and built both the 5-speed and 7-speed tiptronic transmissions for Mercedes Benz, initially declared that the transmission fluid would never require change and that the transmissions themselves were built for a lifetime, never requiring “service”. That belief lasted until those first transmissions reached 50,000 miles and began exhibiting behaviors consistent with thermal breakdown of the transmission fluid and a reduction of the effectiveness of the transmissions internal filter due to time and mileage. Basically, customers starting complaining about rough shifting, failure to downshift during attempted acceleration, unexplained transitions to limp mode operation, and being stuck in a single gear (generally 2nd) with no way to recover. My twenty-give year old ML320 (W163 with the 5-speed 722.6(66) tiptronic once got stuck in reverse. Thankfully I lived not far from the Mercedes Benz dealership back then and I literally drove the back streets IN REVERSE to the shop, much to the amusement of the service manager, not to mention my embarrassment of picking up a local police escort. I’m pretty sure I haven’t lived that one down; but the story does resurface on occasion. Because the transmission was engineered to be a “sealed system”, the vehicles were delivered with no dipstick, just a tube running from the engine bay to the transmission itself, physically connected but with no dipstick provided. According to one of my Mercedes mechanics, the tube was there only for use by the service department (I stopped trying to make sense of the circular argument of a no-service-required transmission having a dip stick tube but no dipstick, with the logic that it was there only for the service department’s use, for providing service? I haven’t mentioned that there is no way for the vehicles owner or a shop not equipped with specialty tools / equipment to add transmission fluid even if it’s needed. That topic is another can of worms best left to the mechanics to explain or address. But I digress. When you unpack the dipstick, don’t be shocked by its size. This thing is VERY LONG and I mean EXCEPTIONALLY so! At first, I thought I had been shipped the wrong dipstick but I hadn’t. It’s giant at 48 inches in length. It’s flexible as it must be to snake it’s way to the transmission, which is situated a fair distance from where it’s dip stick access tube emerges in the engine compartment. The dipstick is well constructed from what appear to be quality materials. It meets the ZF OEM specification (a specification that wasn’t published (it probably didn’t exist) until well into the 722.6 series of transmissions early lives). Compatibility is guaranteed by design. Please follow the instructions published in the W163 and W164 STAR database (specifically the ZF transmission service addendum) for checking fluid level and remember you must remove the dipstick following the check. Those series of transmissions are not engineered to operate with the dipstick left inserted. The dipstick is easy to use. Locate the transmission access tube, insert the dipstick, remove it, review the fluid level on the dipstick using the level markings (the markings are clearly visible on the measuring end of the dipstick), and then visually inspect the fluid condition or use an electronic, automatic transmission fluid (ATF) analyzer for improved accuracy. Personally speaking, the dipstick is a game changer when it comes to this series of automatic transmissions. The twenty six year old ML320 sitting in my livery has a transmission issue currently. Experience tells me that, at a minimum, it needs a transmission service (fluid change, new filter, new pan gasket, and new pan bolts). It could also need a new conductor plate (a common failure in many of the higher mileage 722.6xx transmissions) or the pass through interface to the transmission control unit (TCU). The Mercedes Benz STAR diagnostics tools or a Mercedes Benz M-class specific scan tool can help you diagnose transmission faults. I long ago invested in the transmission fluid vacuum pump / bulbous storage reservoir for evacuating and ultimately refilling all of the fluid in the system (including that in the torque converter). Price wise, the part is inexpensive. It works. It delivers value and that’s good with me. I’d order it again.

Description states this should work for an e430 with the 722.6, however, it's too long for this vehicle.

It’s a great tool to check the transmission fluid level on your 722.6 Mercedes-Benz transmission. I was doing full fluid flush and this dipstick helped fill it back up to the correct level. There are two marks on it - one to check the level when transmission is cold (25C) and the other when it’s warm (80C). Just make sure you follow your car’s manual. I would definitely recommend it.

Works well

Since the engineers at MB in their infinite wisdom decided not to use an engine oil dipstick what may help is this: although this is an accurate and durable TRANSMISSION fluid measuring dipstick, it can be used to check engine oil too. For the W-203 3.2L V-6 engine requiring 7.9 quarts, the perfect full line will be exactly 6.5” from the end of the black plastic tip up to the metal snake. Hope that helps for anyone looking to check their oil in addition to transmission fluid.
