1. Automatic Transmission Dipstick for Dodge Nitro 2007-2011 4.0L NAG1/W5A580,by Mijibisu
This tool earned its ranking through solid compatibility with 4.0L engines running the NAG1 transmission. I'd rank this first for specific swap projects where factory parts fall short.

Buyers frequently mention that this tool fits the 4.0L NAG1 setup accurately.
The lack of a permanent locking cap means you must remove it after checking.
Users note it serves as a reliable garage instrument for fluid maintenance.

An interesting feature here is the calibrated measurement markings designed specifically for 4.0L NAG1 systems. I would point DIY mechanics toward this tool when they want quick verification during fluid changes.

4. kweiny Transmission Dipstick for Chrysler Dodge Fiat Jeep Some Models-Steel
The most common complaint about this multi-vehicle tool is that the universal length requires careful reading against your specific factory manual. I view this option as a flexible backup for multi-vehicle owners who work on several Chrysler platforms.
You get a durable steel construction that withstands frequent garage use. I think the versatility outweighs the slight learning curve for reading the generic markings. Just verify your exact fluid levels twice before buttoning up your vehicle.
Reviewers point out that the steel build feels sturdy and durable.
Users note the universal markings require careful cross-referencing.
The lack of vehicle-specific instructions means you must know your target fluid levels.

Choosing Between Them
I'd suggest choosing option two for your standard 3.7L engine, as it matches the most common configuration on the road. For specialized engine swaps, the Mijibisu and WELURE options serve your 4.0L fluid checks reliably.
Remember that these factory workshop tools are strictly measurement gauges rather than permanent under-hood fixtures. You must always remove the dipstick and plug the fill tube before driving your vehicle.
