The mid to high transition could use some work but otherwise I like it

So I suppose I've done everything right in importing a sound for a car from TDU2 into TDU1. I've been able to extract it, and open in it in audacity where I made it all the files mono, exported it as a 4-bit MC ADPCM and imported via TDU modding tools. Is there any special step I might be missing? Is there anything else that needs to be done to the sound files to make them work in TDU1? Because as of now, I do not get any sound from the car, its completely silent. I've tried using many different donor sound bnk's, but it remains silent.
