Testing this morning after overnight about 60 degrees outside. Start
it up and it will immediately engage reverse but nothing happens when
shifting into D, 2 or 1. Let it idle in P and tried D every 30
seconds. At 2 and a half minutes it engaged D, and immediately drove
fine. It does seem like a valve or something is sticking when cold
and once it starts moving it works properly.
