AnswerHi, Robert. Hyundai has a very good technical service bulletin regarding this issue and its diagnosis and repair. If you don't have one already, register for a free account at www.hmaservice.com (requires Internet Explorer). Once logged in, enter your year and model and select TSB 05-40-006-2. The site is a little tricky to navigate, so if you have any problems, follow-up.
Basically, the TSB indicates that your problem may be a shorted wire, defective solenoid, crank sensor, or internal transmission issue, and gives a procedure to follow for diagnosis. If you have any questions about the TSB (or anything else), please do follow-up.
