So I was out driving spiritedly through the mountains last night when I started to notice that the car wouldn't stay in third gear. It was fine under acceleration, but under engine braking it was very easy to pull the lever back to neutral (1-finger easy), and under decel and braking it would sometimes just pop out on it's own. None of the other gears exhibited any of the same symptoms.

Recent work done on the car includes Megan Racing motor mounts, ACT HD clutch, CDV delete, and Comp 9lb flywheel. Could something have been adjusted improperly when I put everything back? The clutch pedal has been adjusted per the FSM.

Thanks,
Parker

Sounds like a syncro spring broke. $5 dollar part that will cost $500 to replace.

I think there maybe a Honda Technical Service Bulletin on this problem. It maybe model-year specific. Quick Google got: TSB #05-009.

Hmm, mine is an '04, and it applies to all 2004 models, but it's only a second gear TSB.

Is it possible to buy just this part? The third gear set is >$400 from Honda. I am already planning to pull the transmission again to replace all the bearings in there :/

Many years ago my original box would not stay in fourth without a load and Honda fixed it under warranty replacing a shaft. The problem is likely not related to your recent changes.

My 02 will pop out of 4th upon decel sometimes. I haven't bothered to look into getting it fixed.

It's annoying, but it only happens if I'm cruising under 50mph and it only happens sometimes. Just shift to third or fifth, right? I believe I saw somewhere on the forums that there was a TSB for the AP1s that were popping out of gear.

Not sure if it's related to your issue, just my two cents.

Hope this helps.
