I have a 2015 Honda Odyssey that shifts hard in cold weather ( Canada ), when driving below 40kms. It will jerk into 2 nd gear, when either performing a rolling stop, or transitioning from brake to gas. Had dealer perform 3X drain and fill and computer software update, but issue remains. Even had one of the shift solenoids changed. Funny thing when weather warms up in spring and summer months, shifts smoothly.. Any ideas?

 

Gel filled motor mounts are torn and have let water in that freezes?

 

Thanks for the suggestion, I'll have my mechanic take a look at the mounts. I'm pretty sure he mentioned that he looked at them before, but will double check.
