Weird problem after a night of raising hell. It's shifting weird. As if it were a manual shifting into 3rd at 5 mph and lugging the engine. Weird for a automatic I pull out get to 15 mph and it shifts way up and luggs the engine almost to a stall. I hit the brake and it shifts down to the correct gear. Let up on the brake and it shifts up and starts lugging and jumping again. Takeing it I have a manic converter lock?? Blew the computer fuse a few times messing with the AC . hopefully I didn't fry the computer.
