you need to have your transmission gears rebuilt.

popping the gears out is a sure sign of rebuild. grinding as well with clutch all the way in.

I've had this, I have a new transmission via honda warranty (thanks rob).

it's expensive. about $5000. but most honda dealers will not rebuild your transmission for you. rather, you probably have to buy a new one.

good luck.

 

This is simply not true.

 

I've heard of the 4th gear popping into neutral before, mine has done it a few times, I believe Honda has even acknowledged it with a service bulletin, can anyone confirm this?

 

Maybe. Maybe not. It all depends on the throttle setting. Consider the extremes. If you're coasting, the engine can't lug unless the engine speed drops below idle speed (and then the engine is pulling, or trying to pull, so you are no longer coasting, and the engine will bog rather than lug). Even if you are in fifth gear at 1500 RPM, if you're not on the gas at all, the engine can't lug. No throttle application, no lugging.

On a level road the car will accelerate smoothly from 20-35 MPH, in fourth gear, under light throttle, without lugging. Acceleration has to be VERY LEISURELY because anything more than a light application of the throttle will cause lugging.

Lugging comes from excessive throttle relative to the load. Bogging takes place when the load exceeds the available torque. Slightly different things.

 

If the car is regularly poping out of gears then it is time to rebuild/replace or at least take it in for warrenty.

It may not be true for a car that popped out twice in 10,000 miles, but it's not normal either.

 

Here is the TSB for popping out of 2nd. I have not seen 1 for popping out of 4th.
With the AP2 transmissions, the consensus has been that if you have a low milage car that pops out very occasionally when cold the problem will generally resolve itself by 10K miles of so.

If you have a car which is constantly grinding and popping out of gear hot and cold you obviously have a screwed up transmission and need it repaired.
But the very occasional grind, or cold pop out (especially if you're not sure you put it all the way in gear) does not automatically require a new transmission as Plokivos unequivicably stared

You are correct, I oversimplified. If I needed to accelerate from 20 mph in 4th (Not that I would EVER be there) I would certainly bog. I'm sure there is a scenario where 20 mph in 4th would be 'normal' driving. It's just not one I have ever found myself in.

 

It's possible to have a car jump out of gear because the gear was not fully engaged, and if it's something that happens only once or twice in 10k miles, then it's most certainly due to incomplete shifts. When the car pops out of gear often, it's not normal.

i'd try to use that idea as a last resort, i've read a lot on here where people take their car in, and it seems fixed but the problem reappears and sometimes more gears start popping out. Break in your car, and see if the problem persists.
