test drive or better the engine goes off in reverse
Hello everybody,
I have bought a used Dodge Dakota 3.9 2WD Automatic from 1997, where the previous owner has already changed the engine due to an engine failure at a specialist company. Unfortunately, this exchange was not as successful as desired, because after the replacement of the engine, the car moves only forward. As soon as the reverse gear is engaged, the engine stops. Therefore, the vehicle was also sold with alleged gear damage.Now we have the transmission expanded and also overhauled so that it would now be ready to drive. During the overhaul, we have found no special features and have only replaced the parts that have shown wear. Unfortunately, the driving readiness did not follow yesterday after the gearbox installation of the reconditioned transmission. The vehicle will still go off as soon as the reverse gear is engaged - it does not matter if we insert the gear directly by hand on the gearbox or insert in the vehicle compartment by circuit. It does not matter whether we switch from P to R or switch from N to R. What we noticed was that the engine on N runs a bit restless, unlike P. Whether this error with going out in reverse has something to do with it, we still do not know. Distributor, crankshaft sensor, ignition cable, spark plugs, etc. pp. have been newly installed. I would like to ask you to help me as we really do not know what to do next.
TThanks in advance

When I first saw the post title, I thought you'd been eating beans and was practicing for when you're around people you don't like. Then I saw you were in Germany so Farht means something else there. (Yes, I really am that childish.
) Let's try to line out the exact problem here. When you say the engine stops when you put it in reverse, do you mean the engine shuts off and dies? Since it idles differently in neutral and park, has the torque converter been looked at? Especially the lock up feature? If it locks up at idle it can stall the engine.Now, this is stretching for a cause but I've seen it a couple of times, how about the engine mounts and ground cables? I've been beat by a problem twice where the engine would shut off because of it shifting in place and pulling on a ground cable and opening the circuit.

If it locks up at idle it can stall the engine. Idle is ok
Now, this is stretching for a cause but I've seen it a couple of times, how about the engine mounts and ground cables? engine mounts and ground cables are OK it´s new

At a distance it's a little hard to diagnose and I'm sure the issue may turn out to be minor, but critical. This suggestion is a bit of a jack leg idea but give it a try. Somewhere, where it's safe, set your park brake, chock the wheels and try to go into reverse with your left foot HARD on the brake pedal.With your right foot, add a little throttle to get engine speed up. Now, try to put it into reverse and see how it acts. Does it just die, does it jerk hard then die or what? It sounds like your lock up feature is engaging at idle and not letting the power slip. Like trying to use a manual transmission car without the clutch. Maybe the lock up relay is bad and on all the time, the solenoid is bad, the unit in the converter is bad.

I said the same thing when I saw this post because it's 100% identical (to-the-T) to when my crank sensor failed. But OP says they already replaced the sensor.

Missed that part. Wonder what brand sensor, or if the wires got pinched.

Ok,
I have a crankshaft position sensor which is new. I will exchange it on Saturday against the now installed sensor. Maybe the problem with it from the world otherwise I will order a new converter for the automatic transmission.
Thank you for the numerous help from you.
You are great
