To find a compatible transmission, you need to look for a 42RE from a similar year Dodge Ram 1500 with a 3.9L engine. However, even those might have slight differences (like valve body or torque converter). It's *not* simply a matter of "any 42RE".
To be safe:
* Check the transmission's identification tag: This tag should give you a more precise code, allowing for better matching.
* Consult a parts catalog or transmission specialist: They can verify compatibility based on the specific codes.
Trying to use a transmission from a significantly different year or engine application could lead to problems with fitment, control system compatibility (especially with electronics), and potential failure. A professional assessment before installation is strongly recommended.
