My Jeep dealer tells me I have a "heavy duty 5 speed" and cannot give me a part number, etc.

On the top of the case near the shifter is: 1L507560 he also found this number in his computer, but again no other details.

Previous forum Question go me: NV3550 and AX-15 answers. If the dealer can't tell me, anyone know what the 1L507560 stands for?

Thanks in advance!

Try contacting jeep at the following link

and request the build sheet for your Jeep. This should let you know if you have the NV3550 or AX-15.

 

Compare the transmission cases..

NV3550:


AX 15:

 

2000-01 got the NV3550.

 

Are you just curious, or do you have a specific question?

 

Thanks everyone. No I want to know so I can buy/pull a tranny that fits.

Everyone's been helpful!
