Would replacing this item cure my cars lack of finding its final gear?.The car has to warm up fully before it will shift into its hwy gear,I drive down the feeder of the freeway for a good 15 minutes before it gets its hwy gear.Ive tried trans x after a filter and fluid change with no result.Any ideas?

Check your kick down switch it might be stuck
