some patches

[joevenzon]

I've updated the TC and checked it in since it was a trivial change.

There's no way to post attachments on the forum. However since you've contributed a couple of useful things, send me a PM with your desired user/pass and your sourceforge.net account name and I'll set you up with access to the code repo and the data repo. That way you can check in the downshifting change yourself; it looks good to me. Originally I made it not downshift into first because I was worried about some of the cars losing traction during an abrupt downshift to first, but if you've driven with it and it works OK then I'm satisfied.
