Helical gears make more noise when used backwards...
...straight cut gears are stronger (well they should be!) I'd be surprised if they were fitted to any TN gear box though - as that would have made it a lot more specialised and expensive. These little commercial vehicles aren't meant to last as long as they do - they're not as well built as say a Unimog.
I could be wrong about the TN gear boxes - I'm just going on the Ford Transit ethos => build it cheap and base it on as many high volume car parts that you can.
