What did a G transmission originally come in?

[ConfusedAsUsual]

The transmission has serial number GM 341xxxx on it- it's a replacement installed in my Accord several years ago. I'm having some problems now - and I'd like to know what it is so I know how to order parts, etc.

Thanks.

4 cylinder or V6? Auto or manual?

Sorry - I guess more info would help. Sorta.
Car: 1987 accord LXi Hatchback 5sp

Should (did) have an A2Q5 transmssion - someone put a GM3 in it about five years ago. It's the GM3 I'm trying to identify - what model / year...

So far I have found that the GM1 and GM2 are Civic - The GM3 is not. The GM3 shares many parts with the GS and GY out of 1984/85 Preludes (and the differential bearing is the same as the one in the A2Q5).

So - what did the GM3 transmission originally come in????

Thanks
