I’m currently rebuilding a salvage 2019 Hyundai Elantra 2.0L Limited vehicle bought at auction. This vehicle was involved in an accident and as a result the engine was damaged, I replaced the engine with a donor engine from a 2017 Elantra Same mileage and the engine runs beautifully. I refilled all the fluids, when I tried to drive the vehicle transmission Goes into reverse and when shifting into neutral it still goes in reverse and when in drive it doesn’t move almost like it was in neutral. I want to add that I drove this car before the engine swap and shifted in gears just fine, I checked the connections and cable linkage and everything looks right. Any ideas?
