SOHC trannys are easy, but don't tell my customers that!

Installing the CS lock ring, I just get it squeezed in then use a left over shift shaft to push it down. A lot of my tools are left over tranny parts.

Example on a 88-91 Cable tranny, no pry points.

Use an old shift shaft to hold the case up, then tap at the two flat area on the case to break the gasket sealer apart.



That same "tool" is used to drive the mainshaft out of the bearing and 5th gear hub, I don't have a press. I also use it to drive out the axle seals as well as tap the shifter arm down into the shift fork assembly when dropping the gear stacks in.

See the 1 5/8" socket in the background, used to install diff bearings. Warm the bearing on a heater plate and the tap on real easy.

Something my family being craftsman that I just get a knack for. Only one toy I could never take apart, grandpa got me an anvil for christmas on year. It did aid me in other destruction though

KiDDD, your best bet it to start a thread here and post pics, I love tranny ****!

Seriously though, with the pics I generally see something others overlook, which is why I ask for pics all the time. Just make sure they aren't blurry or washed out from the flash. Most of my old pics are from a 1.2 MP camera that I've had for 7 years or more. Simple point and shoot, sometimes have to change the flash settings in the garage due to lighting, but it works.

EDIT: My camera is a Olympus D-370

I cant believe I missed your post Bone.. my fault. Yeah, I intend on opening the tranny in the next coming week and I'm going to do a step by step as well. My tranny doesnt grind or anything, it simply doesnt allow the 5th gear to engage. After opening the tranny numerous times, (one to resurface the flywheel, another to inspect for metal shreadings which it did have, and another to test whether or not it was the shift linkage that was the problem) and we still cant figure out whats going on. So, with that being said, I'm opening it up again. Hopefully it's nothing major, but if a rebuild is required, Syncrotech here I come, along with a DIY step by step just like this awesome one.

I'm going to rely on you bone to guide me lol.
I will supply all the tranny pr0n possible

I'll bet you either have the 5th gear slider misaligned or upside down.

If this is the issue, I will be one happy man.
This will actually give me the funds to rebuild my y8 instead of rebuilding the tranny. We shall seeeee. I'm going to see if I can open it up tomorrow. Stay tuned...

Yeah agreed. Sounds like a 5th sleeve problem. As Bone stated before..if you cant see an issue, take a few good pics and one of us will figure out your problem.

good to know, thanks for posting up the pics man. Seriously, I appreciate the time you took taking the pics and explaining everything you did step by step. With help like this and bone and some other guys, tranny noobs like me have a chance lol.

In all seriousness, why shouldn't I just tap the CS bearing back in place, then stake it down? Do I really need the whole rebuild kit? My car pops out of 2nd gear randomly.

You don't necessarily need a rebuild kit, but I always replace the ISB and seal when I take a transmission apart, even if it isn't bad.

You should definitely completely disassemble the tranny and clean it thoroughly. Also take a good look at the gears, sleeves and synchros.

No, you dont have to buy the rebuild kit or the clutch/flywheel. i just figured since i was going to take it all apart then i might as well go ahead and replace everything. i would hate to have to take it all apart later because i chose not to replace something that would have been so easy. i'm so glad i did too.

i paid less on all the parts and doing it myself then i would have by taking it to a shop and having them disassemble all of it and then just stake the bearing for me.

If it's not damaged, don't. Anytime a trans gets opened up, it gets torn down, thrown in the parts washer and all shafts disassembled and flushed. I couldn't tell you the last time I replaced a clutch housing CS bearing...

Don't stake it too hard! I learned my lesson years ago- you can distort the bearing and the CS won't sit true...

Noted thanks!

Also, I don't have anybody to help me with this. I'm in pretty decent shape, can I remove the tranny by myself with the car on jack stands? I don't imagine a empty honda tranny could weight THAT much.

Just trying to make sure I'm completely ready before I take this on. I got the shop manual too.

Yes you can. Transmission weighs about 75 - 80lbs.

I would also recommend pre-ordering the friction dampers if you're really going to tear down both the shafts and clean them out. I would also replace all the seals although it's not really necessary.

I've seen exactly one bad friction damper in over a dozen D-series trans I've torn down. It happens, but it's not common enough that I'd run out and order new ones before I pulled the trans apart.

I always replace the input shaft seal and the 3 crush washers for the detent bolts (failure to replace these can cause shifting issues) The axle seals I replace on an as needed basis, especially where you don't have to pull the transmission when they go bad.

I keep the dampers on hand, but 90% of the time no need to replace.

I always do 4 seals+shift boot and ISB on any tranny I open.

One of mine was bad so it screwed me. I think both together are like either under 10 or under 20 bucks... but I'm not one to advocate throwing parts at a job so if they don't normally go I'd just throw the dice next time.
