Have a 92-93 Integra GSR YS1 transmission with a worn out shift fork and rod (1-2). Already ordered a new shift fork, but the part number is discontinued for the shift rod itself. Is it possible to use a fork/rod from a 94+ hyrdo trans if I'm still using the older 92-93 YS1 main/counter shafts?

 

Bump

 

Yes, GSR YS1's are internally the same as 94+ B-series tranny's

Thanks. New problems though. I'll start from the beginning.

I originally had the trans "rebuilt" by a transmission rebuilder that I know. It turns out, all he ended up doing was putting in new bearings, plus new synchro rings and springs. After I got the transmission back, I had a bad grind going into second, unless you granny shifted, really slowly.

I took the trans out, and put in a brand new second gear, because I figured the dog teeth were worn out, which they were. Put the transmission back in, and still ground second.

Pulled the trans out again, put new shift forks on 1-2 and 3-4. Now, it still grinds second every once in a while if you're coming on to it. It's hard to go into first, even at a dead stop. 3rd also grinds worse than it did before, and it won't go into second on the downshift.

The only thing left I can think of, is the actual synchro hub assembly itself. Any idea's?

 

Saying that it was put together correctly your problem will be the teeth in the sleeve set. Synchro's wont do anything on their own without the corresponding gear in good shape

 

Condition of clutch? Have u tried adjusting the cable?

I'm suspicious of of the assembly because even though i put in a brand new second gear, it still ground, and then eventually It became next to impossible to get into first if the car is running. Same with second.

Clutch is new, it's not either of those things.

 

Take a look at the slider on the hub assemblies. Look at the inside of the slider at the teeth. The teeth should be pointed on the top. When they are worn, they round off. When they are really worn, the are flat. Thats more than likely causing your problems.

 

I put new hub assemblies on 1-2 and 3-4, plus they came with a new second and 3rd gear. The teeth on the hub's look really chewed up. I just have to get the trans back in the car now.

 

Did you just replace the hubs or the hubs and sliders?

The whole synchro assembly, new sleeve, new hub, new rings, new springs.

 

Shift forks good, shift selector, mounts, linkage?

The forks are new, the selector seems good, the mounts are innovative billet aluminum, and the shift linkage is cut and rewelded b series linkage

 

Okay, I haven't started the car yet, but here's what I have.

The trans will reluctantly go into second, with a hard pull. It won't go into 1st, 3rd, or 4th, and will go into 5th with some effort.

I rebuilt one shaft at a time. Took each gear and hub off one piece at a time, and set them aside, in order, facing the same way they came off. Everything went together fine. I took my time.

It looks like I'll just have to light the car on fire. I have over $1000 of oem parts into the transmission trying to fix it, and every time It goes back in, it's worse than before.

 

And now that the car is on the ground, my throw out bearing is suddenly noisy as hell, and the car will sometimes go into 3rd, and then no other gear, and then all of a sudden it will only go into 4th, and no other gear, and I can't get 1st or 2nd no matter what.

 

Are you sure you have the sliders and hubs aligned correctly?

Yep. It shifted up and down on the shaft fine, fully assembled. Specifically 1st and second. The shift selector in the transmission is fine. New forks, straight rods. I'm pretty much ready to give up.

 

With the car off, I can push it like i want to go into gear, and if you rock the car back and forth, it'll pop into gear. As soon as you start the car, put it in neutral, let off the clutch, and then back on, it won't go into any gear at all.

 

With the trans assembled does it go into all gears? If it does and the problem only comes when its in the car, something is not assembled right, or clutch is bad/not adjusted correctly.

 

It'll go into first with the car on, but you really have to wiggle and force. It'll shift into second with a crunch, same with 3rd and 4th. 5th is also hard, and reverse is extremely hard. I didn't even touch the 5-R hub assembly or anything, all I did was replace them in the order they came off.

All gears are shifting very poorly, basically. It's not the clutch.


There was nothing re-used as far as second and third gear go. Brand new 2nd, 3rd, hub, sleeve, synchro ring/spring...everything. I reused the original 1st and 4th, with new synchro rings/springs.

 

I meant does it go into all gears with the trans assembled off the car? Did you use a new countershaft 2nd or a new mainshaft as well?

 

I didn't check to see if it would go into gear out of the car, because I "assumed" that it would work once i practically replaced everything possible in the trans.

I replaced just the countershaft second (the one with the dog teeth) and both the mainshaft and countershaft 3rd gear.


The plan right now is to drop the transmission again, take a spare case, cut the top portion in half, bolt it back on, and look at the shafts while I manually shift the trans outside of the car.

 

Thats not needed. Just shift it out of the car.

I have several spare cases, plus If I shift it outside of the car without being able to see what's going on, I'm not that much better off.

I'll also be splitting a virgin trans open and simply comparing the main and counter shafts. Something is probably missing, or upside down.
