2006 Mazda 6 - Won't shift passed 3rd gear. Please help.?
As you can tell by the title, my main issue is that it will not shift passed 3rd gear.
It hard shifts into R when i first start the vehicle.
It shifts rough from 1 > 2 > 3, but then doesnt shift passed 3. If I come to a stop it will down shift back to 1 and the cycle restarts.
The AT codes that it shows are: P0715 & P0766.
I hope this is enough information to at least get some ideas of what I might try to fix it.
