View Full Version : Thoughts on new manual transmission?

I got my warranty replacement transmission last week. Instead of the '88-'89 E2R5 transmission, however, they sent me an '86-'87 A2Q5 transmission. I know the A2Q5 trans will bolt up and work just like an E2R5. I know the car has no value so accuracy in restoration will never count for anything, but still it bugs me to know that I won't have the right transmission in the car.

Am I being way too much of a weinie? Does anyone know if the A2Q5 is better, stronger, lighter or anything that might make me want it over the E2R5? Should I call up the yard and ask for an E2R5 and take my chances that they won't have one?

Thanks!

TO me it was the same snooz. I think the final drive is alittle different but other then that strong wise and exc. is the same. So i wouldnt really worry bout it.

I would call and ask why you weren't sent a E2R5. Although the A2Q5 is compatible it was replaced with the E2R5. If it was just the availability then let them know that you are willing to wait the extra time to get the E2R5. Honda put the E2R5 in there for a reason.

Ask questions.

I have an a2Q5, it has a little bit better gear ratio I believe, the carb cars don't have the same horsepower so the lower gears are shorter I believe, as is the final drive, the end result should be better acceleration with the FI car.

The FI cars have the slightly higher final drive ratio, but the difference is pretty small.

carb cars got the longer geared for mpg and efi cars got the shorter gears... i honestly liked my 88 lxi one better then my 87 carb one... was a little funner to drive

The difference between my '89 LX-i (E2R5?) and my friend's '86 LX (A2Q5?) were pretty noticeable. Mainly, the gear ratio. Her car can pass 40mph in first gear, my car is screaming by 30mph.

Both the A2Q5 and the E2R5 are FI trans, so the gear ratios would be the same, right?

Oh, I thought one was the fuel-injected transmission and the other was the carburated one.

According to the post below you , you have a "DX & LX/ 1986-87/ 5/ A2Q6"
which sounds about right as u have a 86 DX . pretty easy to get the last number mixed up tho...


and Btw Snooz if there both LX-i trans there should be no difference and i would not worry about it .

Help! Get me out from under the rental car bill!

I have a carbed '89 Accord LX A20A1 engine, serial number 3536572 with 5 speed manual transmission that has no sticker on it.
The 5 speed manual transmission that came out of my car has 21 splines, and a pilot shaft end of 12/16" dia. (about 3/4") and a tip length of 3/8"
I can see by the wear marks on my original transmissions pilot shaft that it had a fairly tight fit into a hole
in the end of the crank.

The last manual transmission I have had to pay return shipping on had a much smaller pilot shaft end around 9/16" dia. with 21 splines and a tip length of 1/4".
It had a sticker on the bell housing that said A2Q6.

The newly arrived replacement transmission (from a different company) has a pilot shaft end around 9/16" with 21 splines and a tip length of 1/4"
Same as the 5 speed that I just sent back. It has no sticker at all. They say it is the correct
manual transmission for my car, just like the other company said.

I know the small pilot shaft will fit into the much bigger hole.
I don't feel good about that amount of slop in the pilot shaft if this goes into the hole in the end of my crank.
If It breaks after 6 months warranty, it will cost me another $600 plus shipping.
Plus another rental car bill.

What do I need to tell the transmission people so I can get the same pilot shaft diameter as the 5 speed manual
transmission that was in the car?

Jeez dude. One thread is sufficient. Go put that trans in and get rolling.

Are you saying that a person should put in a transmission that has 1/8" of slop around the pilot shaft?
Won't that cause it to first wear out the front transmission bearing and eventually transmission failure?

Not knowing if anyone would see my post at all in a thread that was years old, I found that a new post
might be seen.

I'm not sure what you are measuring, but any of these transmissions that were designed for the A20 will fit any other A20, the only differences are some of the internal gear ratios, the case, out put shaft dimensions etc are the same. This includes the A20 installed in the second generation prelude, the blocks and transmission cases are identical. Actually if you don't mind giving up a slight bit of gas mileage due to gear ratios, the most fun to drive ratio is in the second generation prelude ones

Nothing against you man, NOBODY knows what I'm measuring. Including the people selling the transmissions.
But if they can make plenty of money selling the wrong ones (which cause clutch chatter and eventual failure)
to people over and over, why should they change?

I'm trying to figure out specifically how I put a picture up on here.

An A2q6 tranny has a tiny pilot shaft or input shaft 9/16" (barely larger than 1/2") and lots of slop when put into the hole in the end of the crank.
An E2R6-020 has a 3/4" pilot shaft or input shaft and fits perfectly in the end of the crank.

E2R6-020 is the tranny that was in the car. The engine that is in the car is A20A1

Another tranny that may fit is an E2R5.

There are plenty of my needed transmissions on shelves across this country and no one knows
that they have them because they are selling enough of the tiny-pilot-shaft-doomed-to-fail ones.

Ok folks, I'm telling you secret stuff that I am the only person in the US knows. 21 splines 3/4" diameter pilot shaft/input shaft, 3/8" long not counting tapered part.
The dummy pilot shaft is the one that fits my clutch and into the end of my crank. specs are above. The tiny pilot shaft or input shaft on the tranny is what I was sent. that has slop in the larger hole that is in the end of my crank.

7197 You can see difference in size compared to the other pictures. Can you see how close the end of the smooth shaft comes to the splines. This pilot shaft or input shaft is tiny and has a lot of slop when in the hole in the end of the crank. The length of the smooth part is only 1/4 long compared to the one that came in the car length of 3/8". I don't know why the picture came upside down. If someone knows how to rotate it, feel free to do so.

Some had a pilot bearing, some did not. I'm guessing you need to install a bearing that your old tranny didn't need.

For some people it becomes easier to compare 9/16 and 12/16 than it is to compare whatever they are teaching in common core.
I don't want someone to go nuts saying that they can't compare 9/16 and 3/4...... lol

None of those transmissions had factory bearings. The pilot shaft/input shaft fitted into a proper size hole in the crank.
Honda doesn't sell those bearings and in some cases won't even know what you are talking about.

I now sell those bearings.
I am the only person in the country who can prevent premature transmission failure.

He took the time to figure out something that no one else has. As long as they aren't priced too far out of line with what sourcing one yourself would cost, then I'd have no problem ordering it through him. It would be cool of him to post the part number, though.

Yes. They did. 91006-634-004. We had the same problems 15 years ago with Honda telling us the bearing didn't exist. But we were looking at it. On vehicles that had never been apart. So we started just keeping them in stock. It was the same bearing for everything, civcs, accords, any four cylinder from the 80's and 90's. If it had a bearing. Not everything did and we couldn't always figure out they why or why not.

SKF-60022 RSJ 15mm inner bore looks like.

I still dont think the mainshaft sticks that far out past the flywheel even to get into the crank. Either way I just flipped 335k miles on my 5 speed with no bearing. How I manage to get to work everyday in my car still a mystery after all these years.

The bearing goes in the flywheel if memory serves me.

Jafir
11-10-2015, 03:57 PM
I think it was the 1987 and earlier accords that had it. And most of the civics even into the 2000s. So your 1988 might never have had it. There might have also been difference between us and Japan built cars. I'm not sure.

Why would the mainshaft sit in the crank? Doesn't that kinda ruin the whole point of having a clutch?

Nope, because it would be in a bearing. Lots of manufacturers do it that way, pilot bearing in the crank shaft. But these go in the flywheel, I'm pretty sure.

That would make sense. My Exedy clutch kit for my 1g came with a pilot bearing. It would have pressed into the flywheel and did fit the end of the input shaft. But I've never seen one actually installed in the car, so I didn't put it back in.

06-20-2016, 09:31 PM
So, Honda says it doesn't exist ...because it literally does not exist on the block. It sound like there are no issues with friction or interference. Adding that bearing almost sounds unnecessary. It would just be another part that wears out, adds resistance and needs replacement. If mine doesn't have one, should I really add one?

Oldblueaccord
06-21-2016, 10:01 PM
Well i don't have one I got 336k. I just did the clutch about 5k miles ago I never gave it a thought. none of my flywheels have enough room for a bearing but ill recheck again.

If your car takes one sure it cant hurt its just a roller bearing that helps support the main shaft.

Double check it fits on the trans main shaft and everything clears ok.

Take some pictures I am curious despite my post sounding negative.

Hi I am new to the 3gen accords. Mostly prefer the cb7 over these, but hey a free car is a free car, however when I obtained this car the transmission was gone do to the previous owner f**king up and broke the housing do to a bad mount. Now I own a 1988 accord coupe lxi with no tranny... bummer right. It is a five speed. The problem is location of another transmission for this vehicle. Like no local wrecker has one and I am trying hard as hell to think of somewhere one might be or if someone might guide me in the direction of where to look for one online.... anything is helpful please. Also I am a "newb" on this site so I am apologizing in advance if I posted in the wrong section. Just kinda need to get her going again. Thank you :)
