i met somekid online that lives 4 hours away with a 90 RS 2 door integra 5speed.. before i take the trip i wanna know what hes talking about, he said his tranny's code is A3 and the car is completely stock, he says it says A3 on the front plate of the tranny, anyone have any insight?

 

As far as I no there aren't any plates on the pre '96 trannys.The 90/91 trannys were all the same small shaft cables.Are you sure its a 5 speed?

There are plates on the 90-93 Integra trannies, they are located slightly to the left of the engine block code. It should say S1 and then have a number which is the tranny ID # if it's a 90 Integra RS 5 speed. There are no letters in the tranny ID # either, so I don't know why it would say A3, because the auto says MPRA. This pic is from a 93 Helms, but I am pretty sure the 90 has a sticker as well.

 

My 91 A1 has a plate in that location.
