If the speed sensor signal to the ECU is not present then the ECU restricts itself to limp home mode like you desribe. You need to sort the speed sensor or its wiring.

You need to check your speed sensor - and the circuit supporting it!

Note you use the correct wiring/procedure for your model year.

If this all makes no sense to you get someone else to do it
