Remove speedometer cable on TRANSMISSION end

[Brennan]

You think a newbie does?? haha..

I was referencing that post by pickupman:

86-87 DX & LX....A2Q6
88 DX & LX.........E2Q6
89 DX & LX.........E2R6
86-87 LXi...........A2Q5
88 LXi................E2Q5
89 LXi................E2R5

85-87 Prelude FI.....A2K5
88 Prelude 2.0 Si......D2J5
89 Prelude 2.0 Si......D2J3

86-89 Integra..........CG


86-87 Accord/Vigor 2.0SI (B20A)........ B2K5
88-89 Accord/Vigor 2.0SI (B20A)........ F2K5

Mine says it clearly on top of the transmission what part number it is. Does this help you see what I mean?

[pickupman6]

Yes the a2k5 is the one he was talking about. If this is a dailiy driver I would stick with one from a carbed car. I liked my old trans much better.

That's what it sounds like my best option would be, as I use the car for deliveries and I would love to see that kind of fuel savings. I do like to drive kinda fast at times, no problem there from your experiences?

[pickupman6]

Nah from carb to fi there isn't much of a difference in performance, however with a fi trans at 3k I'm running about 70, with a carb trans I was running about 79 at 3k.

[Brennan]

Sounds good, if no one has any objections that's what I'll be looking for tomorrow

make sure the speedometer gear is with it, like I said the gear on the sender is different for the different final drives in the tranny, but the output through the cable is the same, the gears in the sender compensate for the difference

Alright, will do. The one I got before they just chopped off the line from the engine so I'm assuming the replacement will be the same. Besides that, no reason not to go with carb'd? I would LOVE to see an increase in MPG..

If you can get an 86 trans that works, put it in. They have a slightly different case, but the innards and bolt pattern are exactly the same. They use the same case gaskets and rebuild kits. MT's are getting scarce and the ones that are left are usually fubarred. If the trans works when you get it in, thank your stars and drive happy. If you nitpick, you're probably going to end up with no transmission at all.

Well I got lucky I guess. They found a carb'd 89 for me and pulled the transmission.

The speed sensor on the 89 has one power steering line port broken off, but I snagged the sensor from the 86 before I returned it (and the 86 was carb'd since they only made carb'd that year, right?). The guy even let me have all the bolts and some other parts since he pulled it straight off an engine. haha...I'm happy.

[pickupman6]

Nah they had lxis in 86. I think even the 85 sei was fi

[Brennan]

Oh ok, nevermind. The speed sensor should work just fine though you think?

[ecogabriel]

x2...

[pickupman6]

Yes it should work fine. I don't see why they would be different. The ring that it rides on is on the differential so it should be the same from carb to fi. There's no reason for them to be different, even though the the trans have a different final drive.

Don't count your chickens before they've hatched. That trans isn't in and working reliably yet.

[Brennan]

It's in and I drove it several blocks and it feels fine. I need to adjust the free play in the clutch cable (and teach myself how to drive stick again cause I've been borrowing my dad's automatic) but besides that it's a success

One last thing... I only had Mobil 1 5-30 on hand so I filled it with that. Not gonna harm it right? Full synthetic, and the high mileage formula so I thought why not?

[obdriver6]

It shouldn't be a problem! I use regular 10w 40 Mobil 1

[Dr_Snooz]

Nice work. If you don't lose fifth in the next year, you'll be doing well.

you shouldn't run full synthetic in a manual, theres not enough friction to let the syncronizers work right, it's actually too slippery

Would synchromesh work on those boxes?

I am using it in my 5G Civic and I am happy with it. However, it costs almost the same as Honda MTF, although synchro is easier to get - I do not have to go to the dealer to buy it

I've heard that several people have had success with it, it's for manual gearboxes and has the friction additives to make the syncros work right

I have heard it is gentle with yellow metal (synchros)

[Brennan]

Ok, I'll drain it and get something different ASAP (read: when I get paid :P)

What's recommended? Redline MTF or ...? I could go crazy and get Royal Purple SynchroMax

Damn, I never thought I'd love this car

PS-Dr_Snooz I have the 4-door version of your sig, same color.

just get regular GM syncromesh at the auto parts store, these trannys originally used motor oil, but I believe the Honda fluid supersedes that recommendation now, the syncromesh will work just as well and isn't as expensive

[POS carb]

I've run Valvoline Racing 20-50 in the summer to Mobile Delvac diesel 10-40 in the mild winter.
Look what came out after 250,000 miles

bad mounts and diff bearing is what finally did it in. all the bearings except on the diff were smooth as new. 5th still looks healthy.
Just keep the oil clean.

[pickupman6]

all of the A20 manual transmissions have the same input shaft, people have been swapping all years of them and 2nd gen lude ones for years with no issues

Stumbled across this, checking out some old threads

Looks like I'm not making this stuff up. I'm not the only one who has noticed the difference. Sorry for bringing back an old thread just to say I told ya so
