Transmission ID - Replacing Speed Sensor

I'm looking for is some info on my transmission. I want to replace the VSS (Vehicle Speed Sensor(s)), but I'm not 100% sure on my transmission model. I'm having trouble finding the sensors on my transmission, so it would help to know the exact model I had, so I can find answers and ask the right questions.

Anyone know how I can identify it? I've looked through the manual and even looked for identification on the transmission itself.

I have a 2005 Jeep Grand Cherokee Laredo 4x4 with a 6 cyl 3.7 engine. The 4WD is always "on", if that helps.

I've been looking at the transmission, looking at parts online, videos online, and diagrams, but what I see online does not look like what I see under my car.

I appreciate it. Unfortunately it looks like the sensors are in the control unit which requires dropping the pan and removing the unit, which might be over my head. It's such an easy fix on other trannies. Oh well.

Type in google search, "everything you ever wanted to know about the NAG1" It should lead you to the mega thread on this transmission. NAG1 =722.6=wa580 =w5j400 with some minor differences.

The transmission is a Mercedes transmission. It was used only in the 2005 Grand Cherokee Larado 3.7.
