Honda Prelude Forum

Did all 4th gen. Preludes come with the same transmission?
I believe there were only two different trannies used in the 4th gen. Preludes.

No. Each engine had its own tranny.
H22 had the shortest, F22 had the longest, and obviously, the H23 was the middle one.

All right, so does anybody have pictures of what each trannny should look like?
How about some tranny codes?

What size clutch discs does each tranny use?

Thanks

4TH GEN VTEC: M2F4
H23: M2S4
F22: M2L5

All of them use the same clutch.
Any other questions?

All right. So the only differences between the transmisions are the gear ratios¿ Besides that they're all the same¿

Clutch disc and flywheels are all interchangeable.

no some trannys came with LSD (Limited Slip Differential)

Does anybody know how much a 92 si 5speed transmission would cost used? new? where i could find one? my new lude's tranny has a bad oil leak and grinding gears... thanks for any help!

I believe a used tranny from the local junk yard should cost you no more than $100 bucks without a core.

Very useful! Much easier to read than the info on Honda-Tech.
This answers most of my questions and clears a few things up for me.

Sticky This.

bs man im looking for a m2s4 trans and its like 700 buck

does anyone know how or can help get instructions to rebuild an h23 trans where as mine is stuck in 3rd gear and it only drives in the neutral position in 3rd and i don't know why can anyone help thanks

yeah i dont think u can get a used trans for $100 bucks from the junk yard. i priced one for mine (d2a4, 3rd gen lude) and it was $300.

order from one of the import places online, you could have a brand new transmission, as opposed to someting that's been sitting in a junk yard, it's only a few more hundred dollars, and think of the life your would get out of it. OR you can swap in a new engine, and buy one of the engine/tranny packages and get an even better deal.

Perhaps a brand new one. You can probably rebuild your damn tranny for less than that. Heck, I've seen a H22 motor without trans. go for $600-$700 on a forum.

Check out LKQ, they sell used tranny's for about $100 bucks, they are cheap! I think it's $75 if you return your old one. Unless they've changed their prices, I'm almost positive that's about what trannies go for at LKQ. I'm guessing $200 tops at any other junk yard for a used tranny.

Can someone translate what the specs actually mean...for example: an F22 M2L5 tranny's first gear sits at 3.307. The 5th Gen tranny's first gear is 3.285. Obviously the numbers are not far off from each other but there is certainly a big difference when driving them. So I guess i am asking what is the unit of measurement or what are these numbers telling me specifically. Please dont just say,"it's the gear ratio man." I can only assume it is a ratio between engine revolution vs wheel revolution. I'm not sure b/c as I said, the numbers are very close yet the gearing is totally different between those two trannys.

Gear ratios explained

awesome. Rep for you!

I read up about LSD trannys on Wiki but I'm not really sure I understand them right.

Sounds like an LSD tranny varies power to the wheels based on which wheels have the most/best friction whereas standard differentials apply the same amount of torque to all wheels regardless of how much friction the tires have. Kinda makes sense, limited-slip probably refers to limiting the tires spin or "slip" on the road... and not to any sort of gear slippage.

Am I comprehending this right?

People are all the time asking questions about the gearing of our transmissions, which one is best, best mpgs, best accel., etc... so I decided I would start a thread that gives us all that information so we can easily direct people to more info than any (scratch that... most) of use are willing to type.

Here's a nice chart of our gear ratios... if for some reason this stops working I can host it from photobucket. The other photos came from some other 'Lude site...

basically, I think.. it may actually send equal power to the wheel with more traction, which a non-lsd will NOT do.

non-lsd can actually send more power to the tire(s) with less traction... i.e. the one in the puddle/ice, etc... this obviously does not help you get started.

so if LSD's are primarily used for people who have traction issues. why is it s uch a a good thing to have with high performance FWD cars?

Does it help prevent torque steer? does it do anything for someone who lives in the south who doesn't track thier cars?

__________________

If the road is wet or you have a tire with bad traction the torque is directed to the other tire that has grip. I can tell a significant difference during launch and hard cornering.

Anyone know if a 5th gen 2.0 Auto/tiptronic Prelude transmission will fit into a 2.2 vtec Prelude, model year 2000, 5th gen(UK versions)? Are they interchangeable, if not any idea what the differece is? They both have M6HA on them with what looks like a serial number after it. There is another code but these are different to one another.
