Thank you for such a complete response! After paying for 2 shift solenoids and destroying an oil cooler line, my girlfriend's son asked me for help. I started researching myself and suspected the trans relay. I bought the relay for $23.00 and replaced. All problems resolved. Hundreds of dollars wasted by not troubleshooting properly. Hopefully he learned from this.
