kreed Posted May 11, 2017 Share Posted May 11, 2017 Several months ago bought a 1966 Riviera parts car and just getting around to taking apart . The engine is a correct MW code but the transmission tag say " KJ 65 1952 " . I am sure this car was raced at some time but can't figure out what this tranny is - it is aluminum and looks like a TH 400. The aqua color is long gone on the tag but these numbers are punched at the bottom. The only thing I can find is from a jeep ?.... that has a KJ code . Any help would be appreciated .

Thanks KReed ROA 14549 There is a historical connection between Jeep and Nailheads. Dont remember the exact details, I`m sure they are readily available via a Google search, but I`m quite sure there is some interchange between Jeep and Buick Nailhead at some point in time.

RivNut Posted May 11, 2017 Share Posted May 11, 2017 There is also a connection for the nailhead style bell housing TH400 to Rolls Royce. Link to comment Share on other sites More sharing options...
JZRIV Posted May 11, 2017 Share Posted May 11, 2017 (edited) Yup - I have "read" 65-72 Jeep Wagoneers used the same nailhead trans case. the nailhead bell lived on after 1966 through Jeep. Not sure about the KJ code specifically as that sounds like a much later code. The jeep trannies did not have variable pitch converters. I think Tom Telesco may have knowledge on this also. Ken, Unfortunately for the owner whoever replaced the transmission in the GS you bought did not replace with a switch pitch transmission unless.....the Buick guts were swapped to the Jeep coded case and I'd think that unlikely. Who knows. Does the trans have a single or dual electrical plug on it? Edited May 11, 2017 by JZRIV (see edit history) Link to comment Share on other sites More sharing options...
kreed Posted May 11, 2017 Author Share Posted May 11, 2017 JZ - The plug is a single . Thanks for everyone's help. Will do a little more research and let you know . This particular car was not a GS unlike the 66 GS parts car picked up in Missouri later in the year which had the correct BS transmission and MW 425 single quad. This non GS car had been raced hard I think thus the incorrect transmission and MT engine . If anyone needs this transmission, it's available for free local pickup. 1 Link to comment Share on other sites More sharing options...
JZRIV Posted May 11, 2017 Share Posted May 11, 2017 OK I was thinking it was from the GS. You have been buying too many cars Ken. Link to comment Share on other sites More sharing options...
RivNut Posted May 11, 2017 Share Posted May 11, 2017 I tried researching TH400 code numbers and have come up with some clues but nothing with a K in it. From what I can tell, All of the TH400 transmission references show that the first letter in the code stands for the car company. B for Buick, Contact for Chevrolet, Paul for Pontiac, etc. R is for Rolls Royce, and I found an E for Volvo trucks. I did not find the codes for Jeep or Jaguar. Im workin on that. The second letter in the code refers to a combination of things. Combination of floor shift or column shift, rear axle ratio, and engine displacement. No where did I find a K code. Are you sure it's not a B with the top and bottom scrubbed off? ? Link to comment Share on other sites More sharing options...

I am amazed this would hookup to a nailhead. Always learn something on this forum ! KReed Link to comment Share on other sites More sharing options...
telriv Posted May 12, 2017 Share Posted May 12, 2017 The Jeep & Rolls Royce used an adapter between the engine & the bellhousing since the bellhousing was shorter for a NailHead" because of the extension off the back of the block. So the strength of a TH400 that's adaptable to a wide range of apps. Link to comment Share on other sites More sharing options...
