So I've got an odd problem for a 2004 Toyota Echo. The second gear, sometimes not always, is hard to engage. If I be real gentle, and just put a bit of pressure, it would slip in. I could also be a bit rougher and get it into second. It's most pronounced when going from 3rd to second.
3rd, 4th and 5th doesn't have the same problem.
I've checked the shifter, cable, cable bushing has been replaced.
Aside from synchros, what else could be wrong?
