The car won't shift from second gear. Found that the erls fuse was blown. I replaced the fuse and the car shifted fine for a few miles; till the fuse blew again. Now the fuse blows almost every time I start the vehicle. Twice now it has started and shifted out fine, but the fuse blows within a mile or two if not as soon as I turn the ignition over.

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it's not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.
