Transmission Dipstick | Fluid Tool | KIT: Instructions & Locking PIN & O-Ring for Cap | 722.6 | OE# 140589152100 | Compatible with Select Mercedes Benz & Sprinter

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.

This is identical to the original Mercedes tool and therefore, should only get a 5 rating. The less than 5 star ratings are ridiculous. I’ve had several other inferior versions over the years. This one has the high-low temp range marks and is not just graduated 1-12 like so many other knock-offs. Also it is packaged in such a way that the tip does not come bent, which is how so many other cheapies come. This one is a real bargain at $11 and is absolutely IDENTICAL to the OE version.Note that there is one rating for "Easy to Install". This tool is NOT installed, simply used and then removed from the vehicle.As far as others giving this less than a 5 rating, I took my time to read some of those reviews and was dumbfounded. With respect, if you don’t know what you are doing in the first place, you shouldn’t be using this tool as you can damage your transmission! Various comments were:Someone complained the instructions were missing. Another said they needed instructions to find their dipstick tube. Again, if you really don’t know how to work on a car and where you should be looking up the WIS (work instructions) information on your car, you shouldn’t be using this tool. Further, the dipstick tubes are in various locations on vehicles with 722.6 transmissions, so the dipstick tool CANNOT come with those instructions.Another complaint was the tool is too long. News flash! It’s SUPPOSED TO BE as it works with various vehicles with the 722.6 transmission and the spring shaft doesn’t go all the way it. The shoulder on the base of the tip bottoms out against the transmission where the tube goes in when you insert it which must be done with care!Another broke the tip off. Again, you should not use this tool if you don’t know what you are doing as you CAN break the tip off. This is not to be forced in the transmission any further than it goes and you will have a lot of the spring shaft still hanging out. This comment obviously came from someone try to force the entire spring shaft into the transmission.Others were unhappy because it didn’t work with their C class, ML350, Sprinter, etc. Well, no, of course not. It’s specifically for the 722.6 transmission. Look up the right part number through a Mercedes dealership for your transmission and then look for the aftermarket equivalent! Or use a reputable dealer like FCP Euro for a cross reference.There was a gripe that the tip is flimsy. It’s a plastic tipped tool EXACTLY like the OE version from Mercedes. Original OE version was made by Febi which you can find for under $25 and it is EXACTLY like this one. The tip feels as tough as the original, which isn’t that tough. Has to be used with care and if the tip starts looking degraded or worn, it’s time for a new one. The tip is plastic on purpose in case that it is ever broken off in the transmission so it won’t damage the transmission internals. A metal tip would destroy the transmission.My favorite comment was a 2 star – The tip is made from a type of plastic that the oil runs off so you can’t get a reading. That’s pretty much the nature of any dipstick. They are challenging to read and you have to use a bright light and do it quickly to see the traces of the fluid.One other said it’s a rip-off because they didn’t get the red locking pin for the cap. So someone didn’t get the locking pin (mine had it) but for $10, I think saying it’s a rip off because it was missing is a bit over the top. If you are buying this tool, I would assume you are going to check your transmission fluid level periodically or why else buy the tool? You would need to buy a bag of the locking pins anyway as one is needed every time you check your fluid as you have to break the old one to check the fluid level. The locking pins are about $5 for a bag of 5. (Dorman part number 917-299)One said they had to leave the dipstick tool out due to length (when operating the vehicle) and hope they didn’t lose it. Really? It’s not supposed to be left in these transmissions under any circumstances. Again, you shouldn’t be messing with your transmission of you truly don’t understand what you are doing.

It did the job. Checks atf levels fine. No complaints

The length is good, but I had to really shove it hard to get to the fluid. If your stick is dry, you may just need to give it more umpf. Mercedes tool was $85, so this worked fine.

It was unnerving to not be able to check my transmission fluid, so I opted to get this and it needed a whole quart! Don't be afraid to wiggle it around a bit, it has a set spot that kind of clicks into place, you get the feel of it easily enough. There is plenty of extra line to it, it doesn't seat fully in like other vehicles, and likely this dipstick would work with most Mercedes that have this "fun" extra feature they forgot to outfit the buyer with. There is a storage compartment in my ML320 you can coil this thing up in so it's always with you should you need it too and I'm sure most Mercedes have something of the same.

Works great.

As described

I ordered the transmission dipstick with O ring and locking pin. The locking pin was not included so I placed a separate order for 5 locking pins for 4 dollars.
