Message :You say the 45P61 superceeded 40P00 for 89-95... Bernie shows the fast system as listing 45P61 as 98 plus with a screen shot. Bernie also mentions p/n 54P21 as the 1996 OBDII replacement. Are you suggesting there is a third part number?

In the USDM catalog, the 45P61 is the superceeded part number for the 0789-0795 us spec trannys.Because of the upgraded synchros,etc.And it is the same part number for the 97-98 jdm z32's.But, the 54P21 is the newest supercession of the 0795-up z32.Which is the OBD2 models.Nissan superceed the trannys 54P21 is no exception.It is newer than the 45P61 which you can get in the states, just has the hole for the sensor.The internals are all the same.I deal with the fiche all day long.
So everybody is right in their own way.The 45P61 is the one in the JDM spec cars, but the 54P21 has the same internals being it is newer in the supercession chain.Nissan wouldnt come out with a new tranny for 95- here and use the old internals, it doent work like that.Just like the 350, all the crappy synchros made the numbers go to the CD009.whether it be a 03 or a 06, cause it is upgraded.Same with the z32.If you look at the part numbers in the fiche for the synchros they are all the same superceeded numbers.No matter what year the car is.So technically nobody is wrong.But yes the 45P61 does come in the 97-spec z32 in japan, no obd2..so...
