    Hi Gents

    I had the gearbox "Checked out" during body work stage and "all looks good" was my response.

    Now that I finally got my RestoMod Electrical work done and ready to run for the first time since I picked up my project 2 years ago I have a nasty grinding sound in 1st and 2nd gear.

    First and foremost - I have these codes on the housing and was hoping I can get as much info as possible by decoding them.

    Secondly, can anyone (after decoding my gearbox) recommend a good quality Overhaul Kit and/or sourcce for Parts so I can rebuild it well?

    Many thanks in advance from waaay south of the Border. Here are some Pics of its current state and the previously mentioned codes.

      The 8B followed by the six digit serial number implies it is a VIN for a 1968 transmission

        Yep,... According to the calendar, it specifically is May 14th, 1971.

        As far as a rebuild kit and source for parts, I would go straight to Brewers performance in Ohio. They have a ton of information on their website and have been very helpful in the past. (Link below). Click on the "Before you order" tab and there is a ton of information to help identify exactly what you have

        That definitely creates a puzzle IMHO, why is there a set of numbers identical to a 68 VIN?
        very curious. Original to the car?

        Could the 3577 be the 357th day of 1967 ? That would make the trans correct for a 68....

            at the bottom of my My 10,000 day calendar in the mopar book it says that the number
            seen does not apply to 1967.

            Per Brewer's Performance page:

            Beginning with the 1968 model year (July 1, 1967), the main case has a small (3" by 7/8") raised, machined rectangular pad on the passenger side of the transmission, just above the casting number. Along with the vehicle's serial number stamped onto it, this pad will have a second line beginning with "PP833" followed by a 4-digit (10,000 day calendar) date code, such as "2264" (10-9-67) or "3055" (12-08-69) and sequential assembly number (405) for that day (pictured).

            The OP is in Ecuador, South America so stampings may be different....?

              The only thing that I could think of to explain would be this,.... What if the transmission was replaced sometime in late 1971 - early 1972 as a factory warranty replacement. I have read in other threads that some dealers stamped the VIN into the replacement part when doing the warranty work. Others said they didn't do that, but in the thread I was reading, someone said their relative worked for a Mopar dealership and said that they DID do that on warranty replacements.

              I don't know what the factory warranty was back then, but even if it wasn't a warranty issue, maybe it was a replacement transmission that was built in May of 71, and was stamped with the 1968 serial number when it was installed by the dealer.

              That or someone replaced it at some point and wanted to make it look like it the numbers matching original (and didn't know how to decode the manufacture date).

              Whatever someone wants to believe......

              it may help to provide the casting number on the case and tail shaft housing. The vin appears to be gang stamped, which dealers had access to. The question is where did the car come from? I don't believe there was a Vin requirement for vehicles not built to U.S. specs. Anyway, the two sets of numbers appear to contradict each other if the car was in the U.S. If it were me, I would disassemble the unit and take pictures so the tranny guys up here can determine what it really is.

              Probably just the input shaft bearing anyway if it only seems to do it in first and second. (about the easiest one to get to):D

              I'm going to say its not original to the car. I'll never really know.

              Car was Imported from the U.S. so stampings are per U.S. standards.


              Gonna open it up and check in the next few days... Thanks all!

              8B can also be from a 1978 Hamtramck built car.

              Can you get a photo showing all the numbers on the pad in one photo?

              An overall shot of the whole transmission?

              Is the main case iron or aluminum?

              Here are all my pictures and I cannot answer as to the Case Material. But it appears to be aluminum from photos. I'll stop by shop tomorrow if I get a chance.

              From what I gather it looks like a '77?

              Thanks for your help.

              Mystery solved. Pea brain here, I should have considered ten years newer. I own a 77' Model Cordoba and should have remembered that. ARGH. My head is stuck in the 60's all the time. 318 or 360? The bodies are totally different down there, so what is the exact model?

              No aluminum case in 1968, so yes, this gear box is from a 1978 model year car built at Hamtramck.

              Of course, my head is buried in the 60's also, when people say 4-speed I always ASSume that is a cast iron case, not an aluminum case overdrive trans...

              Any chance we can figure out the Gear Sets and confirm its an OD?

              The shift rods don't look like they are on the correct arms either. Reverse rod on 1/2 arm now

              The forward shift arm should be up on a later model OD style transmission.

              Put it in each gear and turn input shaft, count number of times input turns to 1 rev of output.

              Very observant! That pic was some time ago, I figured out that the shifting linkage was all messed up before dropping the Gearbox in the car. ;)
