Hi Everyone,

Does anybody know how to identify trannys by the serial number stamped on the case?

 

There were only two trannys used in the ZX, the T-5 in the turbos and the not T-5 in the NA. I forget the number on the NA.

 

Actually, there were 6 different tranny's used in the 280ZX alone, not counting the SIX additional NISMO Factory Competition transmissions.

The automatic - same for all years - '79 to '83
The T5 - same for all years - '82 & '83
'79 4-speed (same as the '77/'78 4-speed)
'79 5-speed (same as the '77/'78 5-speed)
'80 5-speed
'81 to '83 N/A 5-speed

The only one with "well known" markings are the T5's although the casing for the '79 5-speed is visually different than the '81 to '83 N/A 5-speed.
