Silly Transmission Question - Honda Prelude Forum

Crate · 02-21-2002, 03:01 PM

How can you tell which tranny you have? H23 or h22... just curious. Cuse i know they etch h23 on the motor... wonder if they put it on the tranny as well? maybe a distinguishing feature?

Just wonderin.

That's a good question. I don't know myself. Post it in GD too, more people go there.

I know that there is a transmission number under the engine code on the block, but I'm not sure how you can tell the difference.

not sure but i think there is a badge or etched number on it. for hondas i think the code starts with "M" i think.

I don't remember the codes, but the tranny code is on the transmission. Its a white sticker that has like a barcode on it. It is placed sorta near the engine block stamp. You can't miss it. I do know that both of them start with an "M".

It should be about 4 inches to the left of the engine code.

The numbers are as follows:
M2F5 - manual - H22
M2K4 - manual - H23
MP1A - automatic- all engine types.

These are European specs, so the might differ slightly.

Mine says M2S4 - XXXXXXX buncha numbers

hrm.

I assume since the Last number is a 4. It is a h23 tranny as well. hehe.. so USDM H23 tranny is M2S4.....

Aight, I looked at the service manual and the specs for US are:

m2f4- manual- h22a
m2l5- manual- f22a
m2s4- manual- h23a
mp1a- automatic
