Default Bad Clutch or transmission?

The day before it was fine, I wasn't crunching gears or slipping.

I do not race my car, its not fast, and I dont plan on it ever being fast.

I drive it up to daytona, about 150 miles.

As soon as I get off the highway, I cant put it in 2nd.

can barely get it into 1st.


Its REALLY hard to get it into any of the gears.

1st seems to be the only one.


Im able to get into the gears when the car is off.


I check my hydro cluch fluid: perfect.
Check the play to make sure the Slave cylinder is coming out far enough: PERFECT

I had two mechanics look at it, with conflicting answers.

1 said the clutch.
the other said the trans.

What does honda-tech think?

Thanks guys.

most likely if your hydro system master slave ect is working and adjusted propely sounds like the pressure plate may be coming apart

Can you push it into gear while grinding the gears, or it just wont go in period?

I gotta put a lot of force on it to get it into gear.

and when it does, it is not smooth, It does crunch.

FIRST and easiest, I would check your tranny fluid. If it is low it will be very hard to get into gear...

Trouble going in to gear while driving, goes in to gear when turned off? I'd say...

Drain fluid, pull tranny, check clutch/pressure plate/throwout bearing, replace those parts if needed, re-install tranny, fill with pennzoil syncromesh gear oil, and tell us how that worked out for ya.

Worst case scenario, the problem isn't fixed and you need to buy a used tranny from someone on here. If you bought new parts in the first step, you'll have them for the new tranny. Yay!

THis sounds like when a spring popped out of my clutch disk. Super hard to put it in gear and when it would go it it would grind. Sometimes it would drive fine though, I guess that was when the spring would end up back in its hole. If the master/slave cylinders are good, clutch fluid is full and has been bled, tranny fluid is good, then it would point to the clutch or the transmission itself. Can you hear a rattling when you push in the clutch pedal? It seems you need to get the tranny off and inspect the entire clutch assembly

Yup also sounds like a spring busted off the clutch disc to me. Same issues when mine did that. Replaced master and slave, bled them a few times, till the clutch finally gave up, so I swapped it out and had 2 springs loose.

Before I went and pulled the transmission out I would try bleeding/ flushing the clutch fluid. It is brake fluid after all and everyone knows what happens to brake fluid when it gets moisture in it. You are in Florida and it is very humid. I live in Alabama and I replace my brake and clutch fluid about once a year or so to avoid problems like that. If replacing the clutch fluid doesn't work drain and replace the trans fluid. If that doesn't work, pull the trans and check the clutch. Always do the simple things first, It will save you a lot of headache in the long run. I would be super pissed at myself if I pulled the transmission just to find out that my clutch fluid had moisture in it and wasn't letting my clutch disengage properly or it just had air in the lines from some random occurance.

Hello I am his brother with his car in Maitland.

I drove the car and first gear goes in fine when the car is not moving, rev up to 3500 and granny shift at idle and 2nd wont go in. But if you shift quick enough (3000 rpm) to catch the 2nd gear when its matched engine speed to wheel speed it will go in. Same idea for 3rd and 4th. 5th gear goes in great with NO problems. Reverse works from a stand still.

When the engine is on and the tranny is in Neutral if you constantly pump in and out with the clutch there is NO noise! I dont hear a spring I dont hear a whine or a grind. This should eliminate the possibility of metal shards or loose springs between the clutch disc and pressure plate. Also when taking off from first it sounds perfectly fine and has a smooth take off, no chattering no grind, nothin.

Now if the pressure plate is not stopping the clutch disc from spinning how can first or reverse get into gear? The only thing attached to the input shaft is the clutch disc. The Synchros move when the wheels (axel) move. As the wheels turn the synchros keep all the gears closely matched until you shift into them. This explains why the tranny shifts into all gears EASILY when the car is NOT moving but simply with the engine on. In fact you could shift into any gear from a stand still and move the car. but once it gets rollin the 2,3,4 syncros cant match up.

I dont understand how it just happened so quickly, but it did.

How else can you tell its a tranny problem? What are the signs the synchros are bad?

Shift linkage, Fluids, and slave cylinder are all working fine. No broken parts on the shift cables, No leaks of any kind on the slave or master. Trans has no sign of leakage. Its very clean in the engine bay (he has never washed it or anything either). I dont think its the clutch because if it was all 6 gears wouldnt work and it would slip when you accelerate or decelerate with it in gear. The final answer to this riddle will be told within 3 days.

I sounds like your syncros are busted up. The syncros are what slides in and out of gears. I have similar issues with my 1st gear as well. But no where near as extreme as what you have here.

True but this wouldn't happen all at once, what are the chances that all of his syncros went out at the same time...? Not very good odds I'm guessing...

Do synchros go gradually? or CAN they simply go bad right away? If their is a chance to lose 2,3,4 synchros very rapidly then it could have happened. Sure it might not make sense but if the possibility exists it must happen to somebody. People win the lotto every week.

Does anyone have a perfectly clear explanation as to how synchros work? Pics would be great.

OK the Transmission is off and the inspection of the clutch took place at 3:45pm.

Results: Flywheel, Clutch Disc, and Pressure plate are NORMAL. No springs missing or loose, no metal gouges in the Flywheel or Pressure plate. Infact the clutch had plenty of meat on it and could have lasted another 150,000 miles! Infact i dont think clutches have to be replaced until your are at least to 200,000 miles unless you drag race it in every gear! So remember that when you think your having a clutch problem your propbably not! Especially if you know you dont ride on the clutch in every gear.

So the tranny is being replaced at the moment and so is the clutch, the fly is being resurfaced (standard procedure). He is also having the timing belts and water pump done too.

Lessons learned: Synchros can just go simultaniously at any time or whatever broke in there. We will rebuild it ourselves when we have the time and find out what really happened in there.

Till then,
