My 02 civic EX (auto trans) has been having trouble going into, and staying in, gear. My cel light finally came on after it finally quit going into gear at all. I changed the transmission fluid and took it to autozone to check the code. They said "incorrect linkage ratio". It is still having trouble after doing a complete flush of the transmission. It has about 100,000 miles and the manual doesn't say transmission service until 120,000 miles! What gives? Any help would be appreciated....thanks
