That dipstick looks like the oil dipstick on my Polaris RZR, it only locks in the sense that when you push the lever down, it "locks" it in the tube. I wonder if the usage of "locking" dipstick is being misunderstood and it just simply means you have to move the lever to release it?
It seems that this type of locking mechanism would be a way to keep the dipstick from popping out and releasing fluid into the engine bay.
That is exactly what they put in mine. I have another appointment next Tuesday at dealer for clock spring and seatbelt retractor. I will asked them how they intend to rectify this. 100K truck and not able to check transmission fluid level is a joke....Correct, but there should not be any pressure on the dipstick/tube. The vent should not allow it. Apparently, the stubby vent would plug up from fluid seepage/dirt and then not vent. Makes me wonder if there is no baffle at the vent or the fluid level it too high. If the fluid level contacts the rotating assembly, fluid is going to be hard to contain.
The issue of the dipstick being too short to check the fluid level is unacceptable, if that is the case. It for sure is shorter than the oem. That dipstick appears to just be an off the shelf item, not built for the application. Probably sourced from Polaris

Impressive that this Dipstick was good enough for what, about 40 years now?
And now all of a sudden it is a problem? This is a yoke.
This guy claims his '12 dipstick is too long and wore a hole in his pan.

I can see this "fix" as being a problem in the future to someone who is uninformed of why the shorter dipstick was installed. Somebody is going to pull the newer dipstick and see there is no fluid on the stick, think that it is low and start over filling the transmission only to have it bubble up out of the stick and causing a fire or causing a leak somewhere else in the transmission. This seems like the wrong way to fix this problem.
I have not had this problem with my 2009 truck but the dipstick always seems "springy". It must vent well through the dipstick because it never seems well seated but I have never had it bubble up out of the dipstick tube.
Would be much smarter to cut that 15" Stick entirely off from the locking cap so no-one could be confused further down the road. Because then it is very visible that it is a cap only.
No clue why the smart engineer in Detroit could've figured that out.
Ram engineers are in India?
