Frankly, with your questioning about transmission oil temp, I would have assumed it wouldn't have been anything other than an automatic. With a manual the only thing you can do is install heavy duty transmission components. But then you'll be facing the issue of the 1.6L engine. The Aveo was not designed to do anything like this, and IMO it will not be capable of accomplishing what you're trying to do. I'd be expecting an unhappy outcome.
