Hello all, I'm fairly new to this Honda scene and recently acquired an LS-VTEC with trani and wanted to know if there's a code reference guide somewhere on this site to determine what kind I have. thanks

It's the same as your ECU code.

The ECU for a D16Z6 (5th gen Si/EX) is a P28.

The tranny for this motor is also a P28.

Follows accordingly.

It came with a Chrome race ECU. Is there a code stamped somewhere on the trans that would give me this info, or do I assume it's an LS trans since it's an LS-VTEC (B16 head with B18B block). Thanks again.

I am pretty sure it is stamped on the trans.

They say assumption is the mother of all expletive-ups.

State your RPM at like, 80mph.

Somebody could tell you based on the gearing ratios.

Just bring it to a certain MPH (above 30) and analyze the RPM, somebody could help you from there. If not, I'll come back and tell ya what tranny it is . I have to leave now. Go test drive your car and tell me what the RPM are at a certain MPH.

No it's not.

EDIT:
NVM

Maybe it's P20/B000 - though I dunno what's stamped on the tranny, just find a MPH and tell us the speed you are going and at what RPM it was at (specifically) and somebody could tell you what tranny it is from there - unless it's using customized ratios, which is quite possible, though unlikely.

EDIT 2:
Wow, I am very sorry, I was looking at the Ex (my) tranny name...

Whoops, sorry.

Heh, yeah, like he said, Y80/S80

My bad, sorry.

Anyways, method still proves sound, just got to a certain MPH and tell us as exact of an RPM as you can. The honda tachs are a bit off but somebody could make a judgment as to the tranny based on the gear ratios there.

you get a TON of misinformation...

The tranny is probably an S80 or Y80
The problem in that is both LS and GSR transmissions use that stamping - the only way to tell is what rpm you are in @ certain mph....or by opening it up and counting teeth on gears/look of the diff
That will determine your final drive and gearing.
It could be b16/itr (but I dont know the codes for those)

Heylookits shawn

00 si trannies are s4c, integra transmissions are almost all stamped the same, s/y-80

itr trannies and si trannies share the same gear ratio's, only the itr has a limited slip diff. my itr tranny tachs about 4.5k at 80 mph, i think gsr's are closer to 4k, not sure what ls's are. hope that helps
