Re: Occasional Engine Stall Shifting to Reverse

During today's driving around I noticed that the time to shift gears if fine when it's warm, but much slower cold.

Is this something that I should worry about fixing? Right now it's more of a nuisance (and occasional embarrassment) than a big problem.
There are some things the can go wrong in the box that would cause a slow reverse engagement. Thats why I suggested that you check the lag time.
You need a stopwatch, engine/trans, warm and idling. Start the time as you pull it into gear, stop when you feel the engagement. If both are slow, it can just be low line pressure. If the P to N is ok, but the P to R is slower, it can be a problem starting.
If the lag time is OK, then it is likely just the Idle control valve a bit stuck and responding too slow to hold the Idle.
