I have an automatic 2006 Forester and it's sporadically throwing a p0753 code only when I come off the highway (driving 65-70mph+ for 15 mins or so) and come to a stop. The car goes into limp mode and I pull over and clear the code. If I clear the CEL everything works fine (no shifting issues) until I come off the highway again to a stop. If I don't stop (only slow down coming off not letting it go into 1/2 gear) it won't throw the code. Driving around town it seems fine too. Anybody have any ideas why it might throw it only during this time?
