I have '09 TSX 5 speed AT, got Check Transmission and CEL few days back. Car is shifting very rough in 2 and 3 , above 40 mph driving fine. Local Indy mechanic said that's the mechanical problem in transmission and has to rebuild transmission. Quoted $2k to rebuild tranny with 3 year/36,000 miles warranty. I wanted to know whether it's good deal ? If I want to sell , they are asking for $2k. What's my best option, rebuild , use it or sell it now for $2k ? Appreciate any response and thanks in advance.
