by looking at the serial number can someone tell if this is auto or 5 speed... i dont have an ef to test it in..... thanks

 

*Special Thanks to jdmcivic.com, rywire.com, and honda-tech.com for the info:

These ECUs are OBD-0:

PM5 - Civic 1.5l PGM-DPFI (DX/LX) - D15B2
PM6 - 88-91 Civic/CRX SOHC Si - D16A6
PM7 - Civic 1.6 DOHC ZC
PR3 - Civic 1.6l DOHC VTEC (Si) - B16A
* - PR3-J00/J51 Integra B16A OBD-1 ECU
PR4 - Integra LS/GS - D16A1 (87-88) & D16A3 (88-89)

5spd = 000, 001, 002, A00, A01, A10, J00, J01, C01, C00
Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80, L50, L51

 

thats funny... 003 is not on the list... but on the other obd's.. 003 means 5speed... so im gonna say it 5 speed.
thanks for link...

 

If you open the case, the circuit board above the mainboard will have some lettering on its lower left corner. It will say AT for automatic or MT for manual.
