Sorry to start a new thread but I have been searching for answers on here for some time.
Is there any particular reason why Jeep has capped the Transmission Fluid filler tube on the 2006 WK 3.7?
The temperature has really dropped in New England in the last couple of weeks and all of a sudden I am getting a little bit of torque converter shudder and I want to be able to check the level on the transmission fluid.
Is there a dipstick that I can purchase for this vehicle in order to check the level and pull that cap off for good?
Furthermore, does anybody have the opinion that the fluid might need to be topped off due to it getting cold? Would love to hear your thoughts/insights on this issue. Thanks in advance.
It's mentioned in a couple threads, the trick is finding them.
I wish I had a dipstick as well. In my opinion there is no good reason to just cap it off and call it a day. **** happens, fluids leak, and transmissions are not cheap nor indestructible (quite the opposite). Big design flaw on Mercedes' part, bad choice on Jeep's.
Does a dealer charge to check the fluid level? I'm not talking check it while they change your oil though, I mean drive in, ask them to check it, then leave. I have a dealer about 2 miles away, if I remember I'll try to stop by tomorrow morning.

When I asked on another site this is what I got from them.
Since the miller tool for checking your transmission level is close to $70. This is the more economical way of doing it.
10 Step process.
Go to home depot, lowes, etc.
Go to electrical Isle
Pick up 36" or 48" plastic Zip Ties
Walk to counter and pay for plastic zip ties
Mark a line at 77mm, 70mm, and 63mm from the bottom of the zip tie
Open transmission cap, and stick dipstick into hole (since your drive home warmed up your transmission oil, as it must be warm to measure it)
Pull it out and if it is within the range of your lines your ok.
put cap back on, close hood
There is a fluid temp/level graph that has to be used to gain the correct level in the Nag 1 autobox , my CRD with the W5J440 tranny is filled to a level of 68mm at 140 F.
You will need a reliable way of measuring the temp eg.Dashhawk OBD reader,once the temp is reached use the dipstick to measure the fluid level.
Because.... there were inconsistencies in terms of what needed to be put in. Jeep shops showed one thing, manuscript said another.
Everywhere it states ATF+4 only,they even have a TSB stating any Chrysler trans that takes ATF+2 or 3 now takes ATF+4.Only the peugeot trans takes DEXIII,all other require ATF+4,printed in clear writing everywhere.Shops and owners did not look or care as ATF+4 is pricey due to being full synthetic.

Most dealers will charge you to read the ATF level since they have to hook up their scan tool. Probably be their minimun $50-$100.
You can use most anything for a temporary dipstick. On my 06 WK 3.7 I used some 1/4" poly tube that's at least 40" long to reach the bottom of the trans pan. Just measure the length of the wet end of the poly tube or whatever you use with a mm scale. I found the level to be about 80mm after sitting over night in the garage where the ambient temp is around 60F. That seemed to be consistant after checking it on different mornings.
The level obviously changes once you start the engine and the ATF begins to warm up. As mentioned earlier there is a chart showing the level vs. ATF temp. I believe its in a TSB that can be found on wkjeeps.com That TSB originally addressed the shudder issue caused by water leaking into the transmission.
When I did my 30k trans service, I measured the amount of ATF removed and replaced it with the exact same amount.
