Help with the year. I just purchased an 1197R1 serial number 505395 and I cannot determine the year for the SF97. It's not on the data plate either.

Can anyone help? I called AM General, and they even looked at pictures and stayed on the phone with me for 30 minutes trying to help, but said it was reset and couldn't figure it out.

If your unit has the M1097R1 HMMWV, NSN 2320-01-346-9317, with a retrofitted engine, check the serial number before ordering a new transmission for the vehicle.

  • M1097R1 HMMWVs with serial numbers between 500000 and 549000 require the 3L80 transmission
  • Those with serial numbers between 570000 and 599000 need the 4L80E/4L85E transmission.


So basically sounds like you have a 3 speed truck, which would put you at 1993 or earlier I think?

I'd suggest just putting 1990 and calling it good. It puts your truck at over 30 years old which is more than enough for historic license plates in pretty much every state. There is no way for anyone to accurately verify the exact year, and putting it as a newer vehicle doesn't give any benefits in any state as far as I am aware.

Thanks and yes, I put 1992 on the SF 97 paperwork, which seemed close enough.

Can someone help me with my model year. Serial number is 217268. Also it was listed on GP as M1123 but when I try to buy parts on MacMotors it lists the M1123 as having a SN less than 196,XXX.

My M1123 has a serial number 201xxx and it’s a 2002. They made changes and that was the over under on the vehicles serial numbers. I think above 196,000 is the A2 version but I’m not an expert. Mac has a very limited search but they have stuff for all models. Craig is really helpful when I can’t find something. Ext 180

I'm trying to apply for my SF97 so hopefully someone can tell me exactly what year it is. I've searched online everywhere and I haven't found the typical chart that shows what the numbers mean

It doesn’t really matter what year it is. Some insurance companies require vehicle to be 20 years old or older. I have a M1165 that has a serial number 225xxx and I chose 2002 for that reason.

It's not about insurance. They told me it matters to get the SF97 and it has to be correct but they didn't know what year it was when they sold it. Also, most importantly, the registrations that get revoked are the ones that have year model discrepancies.

I had the same issue when filling out my SF-97's at first and the year is subjective. But it seems older is better for several reasons and age doesn't affect the value like a conventional vehicle. At first I wanted mine to be as new as possible because I thought the older the less it was worth, but people were saying that wasn't the case. So on my two, I put 1992 and 2001.

There is a serial number break where the trucks with serial number under 196900 use a different power steering pump and serpentine belt setup (and other some other things as well maybe, but those are the ones I am familiar with) than the trucks after 196900. Then occasionally you get the post 196900 engine in a pre 196900 truck, and all bets are off.

If GP doesn’t know what year it is and you don’t know what year it is how will dmv know what year you chose is wrong? Do whatever you want. It matters to get SF97 because they have to put a year on it. I chose to buy a truck without a year so I could decide what year it was.

I mostly didn't want to get my registration revoked because I feel like the state has unlimited resources to investigate things as compared to GP who probably just doesn't care. If I spend a boatload of money on this thing I don't want problems later.

End of the day you are still going to guess what year it is! I would rather guess older than newer

I think it's an '04. Is there any reason I'd want it to be older than that for registration purposes?
Have you tried to get insurance on it yet? Might be a 2004 but it could have been made late 2003? I went with 2002 on both of mine so I only need to register and insure one vehicle… hahaha just kidding.
