  2. Will a 6 spd manual fit/replace a 5 spd!

    My car has 178K on it, I've replaced the trans fluid with a good synthetic (75W90 Amsoil) and all other shifting is normal.

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hey guys - I've isolated this issue to something that only happens when it is by Mid-Atlantic standards "really cold" (40 or below) and my car is sitting exposed to the weather for an extended amount of time, which is usually overnight at my girlfriend's house as I have to park on the street...
