If it is stuck in gear you may have a bad torque converter solenoid or a bad shift solenoid. If that is the case I recomend taking it to a transmission specialist. Do not go to a standard repair shop as automatic tranmissions are very difficult to diagnose and work on and require special tools and experience and training.
AAMCO tends to be over priced. If you need to find one near you use the search engine on this site and you will see that banner ads pop up on the page and when at all possible they are located as close to you as the locater will be able to place them.
