is there a difference in the 5 Spd transmission between a 1990 honda accord EX and a 1992 honda accord EX

I'm going to say no

but that link shows you the gear ratio on the H2U5 tranny found in the EX.

ok i was just wondering i went to a salvage yard and asked for a 90 ex transmission and they gave me a 92 ex transmission and there looks like a difference in where the Velocity speed sensor is located. i'll take pics when i get mine out to compare the two.

There may be some physical differences, but gearing and function should be exactly the same.

Look up part numbers. Different part number, different part. However, the gear ratios of all CB transmissions (at least all North American CB transmissions) are very similar, and the transmissions are basically interchangeable. You're unlikely to notice a difference if you use a transmission from a different year or trim level.
As for the VSS placement, if it is in a different location, it should still function exactly the same way.


The 1990 model CBs have some oddball things that the other 3 years didn't get... it can be annoying!

1990-1993 DXs, LXs, 1991 SEs, and EX Wagon's used the H2A5 Transmission. 1992 EXs and 1992-1993 EX Wagons used the H2U4 Transmission which was geared slightly more aggressively to take advantage of the extra power in the F22A6. Some 1992 DXs and LXs were stamped H2U4 but in actuality the gearing was the same as the H2A5. 1993 EXs and SEs used the H2U5 transmission which was the same gearing as the H2U4 but with the final drive of the H2A5.
