Replaced slipping clutch. Repair covered under (extended) HondaCare warranty.
3 days after I bought my used civic si my 3rd gear began acting up, it would pop out of gear, grind or simply feel notchy. I had a dealership rebuild the 3rd gear, but within a few days the entire tranmission failed due to "overheating of needle bearings"
Took car in for TSB on 3rd gearset, parts ordered in June and installed in July.
Transmission & clutch issues since the car was new. I reported it to dealer, they did replace 2nd gearset and some other parts. But the problem still was there. After almost 10 years That's great, but for the mileage it's not.
Warranty Replacement of third gear set as a result of the common issue with SI (third gear grinding / ejecting after shift, replicated by the shop foreman when the car suddenly skipped out of gear on the trip). Also clutch replaced (cost 64
TSB finally issued to fix third gear problem
Clicking noise when clutch pedal is pressed. Turns out there is a TSB for this problem and it has to do with the cluch master cylinder. Replaced cluch master cylinder and the problem is fixed.
Occasionally it is difficult to engage the third gear. It is especially noticeable when it is cold outside and the engine is cold. The shop could not replicate the problem. There is a TSB for this problem, but the dealer did not want to fix it.
