I found out the fuse labelled (gauges/back up lights) was burned out but when I replaced it discovered that when I put the car in reverse it pops again. There must be a short in the backup circuit. Is the transmission electronic, does it take any input from the gear selector/gauges to decide when and how to shift? Trying to trouble shoot blind... don't know much about these cars only owned it three days. Problem just started last owner (friend of mine) never had this trouble. Any idea let me know thanks all.
