Transmission shift issue
I've been looking for some answers online but the information is glib and conflicting. My Hyundai Santa Fe, 03 2.7, is experiencing shift issues. Prior to to this the speedometer has been randomly dropping out. My issue is starting out in 2nd gear and shifting up to 3rd gear and that is all I get, even when shifting manually. I would like to know some basic diagnostic steps to determine the cause. Some say vss, others say detent adjustment and I have read it can be the computer or solenoid valves. I'm not ready to just throw parts at it and I am hoping someone has some real knowledge or can direct me to service manuals for this vehicle. Thanks!
