tom1954 Posted August 25, 2012 Share Posted August 25, 2012 According to my repair manual the 54 automatic transmission takes type "A" automatic transmission fluid. Is this the same as today's Dexron fluid that is available today? Link to comment Share on other sites More sharing options...
NTX5467 Posted August 26, 2012 Share Posted August 26, 2012 In the 1968 model year, Chrysler started transitioning from the prior Type A, Suffix A automatic transmission fluid into the then-new Dexron atf. GM readily claimed that Dexron (all of the evolving variations thereof, over the years . . . Dexron II, Dexron III, etc.) are backward compatible all the way to their 1949 automatic transmissions, which also used the Type A atf back then. Personally, I would NOT use the current Dexron VI semi-syn atf, though.As GM has "moved on" to a higher level of Dexron atf, the older stuff is now marketed as "Multi-Make" atf, so you'll have to look farther to see if the particular fluid's main target market is older GM vehicles which would have needed Dexron III fluid. All GM currently sells is the Dexron VI fluid as their new 6-speed automatics require it to work right.Valvoline (and a few others) currently have "hi-mileage" Dexron-spec atf, which also has some seal conditioner already in it. This might be a consideration for any vehicle with an automatic trans with some age or miles on it.IF you look hard enough, you can still generally find Type A atf in some auto supplies or convenience stores. Only thing is that the newer Dexron fluids are far superior in so many operational orientations to the earlier fluids, including the level of things in their additive package.Just some thoughts,NTX5467 Link to comment Share on other sites More sharing options...
