Big Question
Oil pressure?Although it won't explain transmission slips, it is normal with many vehicles, after an oil change, for the oil-pressure light to remain on for a few seconds more than usual before going out. That is because oil changes almost always include a new filter. Unlike the old oil-soaked filter, the new filter, upon installation, is dry inside. When you first start the engine after the oil-change, the oil-pump starts circulating the oil through the engine, but it takes a couple of extra seconds for the oil to saturate and pass through the new dry filter's paper elements to reach the pressure-sensors and turn off the red light.
Next time you do a change, besides the usual finger-lube of the filter's O-ring, take some of the oil out of one of the bottles and pour it into the filter's hole before it is screwed on...but only if the filter mounts downward at an angle (with the hole up) where the oil inside won't run out on the engine block while you're trying to mount it. This should help to pre-lube the filter and make the red oil-light go out a little sooner on the first start-up.
