Re: Prelude/H-series Transmission Codes and Ratios master-list
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.

Re: Prelude/H-series Transmission Codes and Ratios master-list
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?

Re: Prelude/H-series Transmission Codes and Ratios master-list
jus a quick question pls no flaming.
For the list where LSD is placed are those the only transmission that come with LSD from factory. is this confirmed.
i asked bcaz i will be going hunting for a transmission soon, and i called a parts shop they say they have a H23 wit and LSD on it, but from the list i see no H23 that comes with and LSD transmission.
Will post the code as soon as i get a chance to look at it

Re: Prelude/H-series Transmission Codes and Ratios master-list
Ok, so heres a question, the gear ratios are the same but will a P2U5 manual tranny (94-97 f22B1) work for my 90 honda accord (F22a1, h2a5)?

Re: Prelude/H-series Transmission Codes and Ratios master-list

Re: Prelude/H-series Transmission Codes and Ratios master-list
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.
