Pirate has a thread that will show you how to find the gear ratios so that you can compare, never heard of a P2T4.

No to slammedbbs, the higher the number the shorter the gear.

Does anyone know if all of the F/H transmissions on this list have the same cable attachment points? or are all of these transmissions interchangeable with each other?

all the trannys on the list that note that they have LSD do from factory. As far as i know, no H23 trannys came LSD equipped but that doesn't mean that the shop hasn't installed one into an H23 tranny so the code might not be helpful cause we wont know if someone installed one or not.

In this chart, the 1992-1996 USDM Prelude S - BA8 - F22A1 - M2L5 - has incorrect values. It lists the 1-5 gears as:
{3.310, 1.810, 1.232, 0.900, 0.710}

Take note of the 1992-1996 Accord Wagon model 1-5:
{3.307, 1.809, 1.230, 0.903, 0.705}

If you were to round all of the wagon ratios to 2 decimal places, you wind up with the values given for the prelude S, with exception of the 3rd gear of 1.232. Must have been a typo because the first numerical possibility of 1.232 is 53/43, which is tooth count combination that is far to much of an outlier for it to be likely.

The correct values are the ones listed for the Wagon.


I'm going to go ahead and post another table I found on some other forum. I am not going to cite where, because they also said that they'd just copy/pasted from some other forum. For reference.

Hello, I'm new here. I'm looking at these charts you have here. Does it mean that all of those accord years and models are compatible with a 1998 Honda Prelude. I have an automatic h22A4 in mine.
