90 Crown Vic shifting

While driving, the tranny will shift from first and then hold while the engine revs before sometimes shifting to the next gear. What are some of the
things to check besides the oil level and filter?

I'm only guessing you have the AOD trans. That vintage had a plastic connector bushing to connecth the trans throttle pressure cable to the throttle linkage at the engine. They tended to wear out and break frequently as the miles went up. They have a brass replacement bushing that is fairly inexpensive and easy to replace if you have a couple of basic tools and a little patience. If this is the problem, it needs to be replaced ASAP as this cable controls line pressure in the trans. With a bad bushing, the trans operates at low pressure and slips the clutches resulting in failure in a matter of a few miles if it is driven hard. The adjustment of the cable is also critical. You should be able to find instructions for your vehicle in a public library shop manual. Some places like Autozone have much of this info online at their sites. Check that and get back with a bit more info on your vehicle. Someone here will probably be able to help and guide you but, info is needed.
