they took out my trans. and fixed the problem but also tore the boots on my struts/shocks and didnt make it right pretty sorry i thought also made me pay for part of my rental cause the warranty only payed for 7 days and it took them around 10 or 11 days to fix it also not very nice of them. i mean isnt that why i paid extra to start with so i wouldnt have to pay so much out of pocket

Pops out of 3rd and 5th gears, more use makes it pop out much more often.

I bought this car used at 60,000 miles. 3rd gear routinely pops out when driving. around 80,000 miles 5th gear began to get a notchy grind every time I shifted into, and sometimes would pop out while driving as well. Dealership nor extended warranty offered to fix. Never buy a 2006 Honda Civic Si.
I first reported the troublesome 3rd gear a month after purchase. I still have problems with it and just found out there was a TSB on the problem. The dealership never informed me of it. I plan to go in with a copy of the TSB and have this addressed.

I have intermittent problems with 3rd gear. I have heard Honda will replace this at the dealership if you are under 80k - I have yet to try.
