Does Transmission Warm Up While Idling? [Solved]
There really isn’t a reason to warm it up, unless you are in extreme sub-zero temps. Letting the engine idle for a couple minutes should do the trick (that is even a hot debate). If you are experiencing trouble shifting when the trans is cold, it could be an indication of upcoming issues, so get it checked out.1 Feb 2018
