Hi I'm looking to switch out the VTEC Manual with the Accord 5-speed because of the Accord 4.06 Final Drive.

Here's a pic of the code... Came from a 95' Accord...

What engine do you have currently in your prelude? If it's an h series that transmission will fit without issues.

The speedometer will always be wrong if you're not using the same oem stock tire size.

It has nothing to do with the tranny, it's all about the tire size. There is a mathematical formula to tell how much the speedometer will be off when using non stock tires.

All of the gears in the Accord transmission will be taller, you're not paying attention to the final drive ratio, it affects all of the gears. The car will be much slower, top speed means nothing if it takes forever to get there, that transmission is for good fuel mileage, the car will feel sluggish.

The transmission however will bolt up, as far as gears being interchangeable, you'll have to just pull the transmission apart and measure to find out.
