ok, I pressured-washed the 88 Si drive train last night that's going into my 90 CRX DX this weekend. After removing all the grime, I found "ZC" written in yellow grease marker 3 different places on the tranny, and "ZC SOHC" scribbled on the bell housing. Looks like inventory markings from a shop/importer.

I don't know much of the history of the drivetrain, just that it came from an 88 Si parts car that I acquired. As far as I knew, the car had a stock Si drivetrain. Anyway, since I wanted to replace the syrchros with the un-worn DX ones, I cracked open the case to assess condition. I counted the teeth on the final drive, and it has the same number as the DX (69 teeth) with the 3.88 FD. Now I know that ZCs had a 3.88 FD, same as a DX, but a lower 1-5th gearing. The Si trannys have a 4.2something FD(more teeth?).

SO, does this mean it's a true ZC tranny? Sticker says it's an L3, same as my old ZC sedan's tranny.

 

Also, is the SOHC ZC tranny identical to the DOHC one?

 

anyone?

 

just because it says L3 on the tranny doesnt mean anything, because all d-series trannies have that stamp on them, so its very much possible that you have a zc tranny
HTH

 

True, my 89 sedan had a ZC tranny with "L3" marking, but so did the busted stock USDM DX tranny that came out of the CRX. So I guess the only way to tell is crack it open and see what's inside?

 

a true zc tranny will require an intermediate shaft to work right

so they won't work with stock USDM d-series axles? I thought the intermediate shaft was just there to reduce torque steer and increase performance, and that the outside casing of the tranny was identical to all cable D-series.
