I notice on my 2000 f150 with 5.4 engine when it is over 95 degrees outside it seems to take longer to shift and the engine RMPs are higher than when it is 90 degrees or lower. This is in the Fort Worth Tx… Is this common?

The engine rpms are higher because the tranny hangs longer than it should before shifting?

Have you got an extra tranny cooler on the truck?
