Yes, I'm new to forums. I'm purchasing a 1983 CJ8 but am wondering about validity of Vin number and how to decode numbers. The Vin is 1JCCL88E5DT001795. I also have info from seller of numbers J172376 88 and 06 3B 1BA on firewall. I found one site on web that when Vin entered replied invalid number. Jeep is in Texas and I'm in New Mexico trying to do purchase. Am raising 4 grand kids and thought this would be a fun project for us. Thanks for any help you can give.

This is from the FSM for decoding the VIN:

Here is some info on the other tag:

It looks like the "L" may be causing your "invalid number" on the search. :shrug:

Thanks a lot. This Scrambler shows to have approx. 70K origional miles. If it's correct miles, I think it will be a really good one. Also been kept under shed roof on ranch. I think after more research the L may signify a 5 speed on the floor transmission.

Did you get a picture of both the dash vin and the cowl tag? Does the vin number portion of both tags match?

Mine is a 4 cylinder 5 speed from the factory, and starts out 1JCBN88EXCT******

The ‘82 Technical Service Manual lists the following transmissions for CJ’s:

M - 4 Speed Manual, Floor, Part Time T-case
G - 4 Speed Manual, Floor, Full Time T-case
H - 4 Speed Manual, Floor, Part or Full Time T-case
B - Automatic Floor, Part Time T-case
C - Automatic Floor, Full Time T-case
K - Automatic Floor, Part or Full Time T-case
E - Automatic Column, Part Time T-case
A - Automatic Column, Full Time T-case
J - Automatic Column, Part or Full Time T-case
W - 5 Speed Manual, Floor, No T-case
F - 5 Speed Manual, Floor, Part T-case
P - 5 Speed Manual, Floor, Full T-case
N - 5 Speed Manual, Floor, Part or Full T-case

I’d suggest getting a picture of the VIN tag on the windshield by the wiper motor, a photo of the trim tag on the firewall, a picture of the certification label on the body panel by the driver’s seat base, and if possible a picture of the frame above the right rear axle near the cross member that holds the rear brake line fitting (front of gas tank support). The last vin location is only a partial and should only have JC00**** (last 4 are the last 4 of the sequential number). Not sure what the second, third and fourth represent. My 4 cyl frame has a C, but my replacement frame has the second digit as B. My vin for the 4 cyl has a 5 digit sequence number, but only the last 4 are stamped on the frame. The 3rd and 4th digits are 00, same as my replacement frame. My ‘83 Overlander frame only has 7 digits JC0****. Not sure why it only has 7 digits while the ‘82 and the replacement frame both have 8 digits. :shrug:

I have found no documentation of an L type transmission.

Yes both match. I was mistaken in that the M looked like an L on Vehicle ID Plate which according to (Tom "Ol Jeep" Collin) would make trani a 5 speed but it was an M. I read some where that the 4 speed was more desirable.
So hopefully that's true.

I found a site (TOM "OLJEEP" COLLINS) that specified L as a 5 speed trani but both Vin and Vehicle agree on 5th place being a M (4 speed trani). I hope that trani a desirable one. I found two 4 speeds in a that era, a T176 and a T177. Vehicle should be delivered to me Wednesday the 18th.

Just FYI, there were 4 manual transmissions offered from the factory in scramblers SR4, T4, T5 and T176 (identified by a straight shifter). The T5 is basically a T4 with an overdrive. Only the T176 is desirable from a strength standpoint.

Is there an easy way of determining if it would be the T176? I'm thinking there would be a stamp somewhere on transmission. Would I be correct?

What does the shifter look like? Is it straight and tall, like a tractor trailer shifter? That would be a T176.



If it has a dog leg, then it's either the SR4 (worst) or T4 (middle ground). Position of reverse would differentiate these two. Down and right, T4. Up and...right, or left, I can't recall, SR4.
