I have a 1994 Dodge Dakota SLT extended cab 220,000 kms with a 3.9 litre engine & four speed automatic transmission.I started my truck & moved shifter lever to reverse. Can hear transmission going into reverse but transmission stays in park at same time. Does this in drive position also. Can shut truck off & put shifting leaver in any gear & park is still engaged. Is this something that can be fixed with out takeing transmission out?
