Burnt transmission fluid can definitely cause the problems you’re having. If it’s burnt or contaminated, it might be black or very dark red, rather than the nice, clear, bright red it should be. It’s off the to transmission specialist for this one, as the lack of drive could be caused by many things. An experienced mechanic will know this transmission and should be able to diagnose it swiftly.

The bad news is that you might have avoided serious damage if you’d had the transmission inspected when it first started to behave erratically. But continuing to drive it with a problem can often cause further and more serious damage. You may now find that the cost of repairs is greater than the value of the vehicle.

This is really backwards, isn’t it? The ice warning is designed to alert the driver to road conditions cold enough for ice to form and cause a skidding risk. But in your case, the opposite is happening and the car thinks it’s freezing outside whenever the temperature creeps up to 28. This would make most mechanics think that the temperature sensor that reads the ambient temperature has gone haywire and is telling the onboard computer lies.

Either that, or the vehicle is selecting the ice and snow driving mode on its own behalf, and that’s what’s limiting your engine speed. That wouldn’t be dependent on the ambient temperature reaching 28 degrees, however. But if the ice and snow driving mode is part of the problem, you could have a faulty switch or even a problem with the car’s body computer. An auto electrician is your best bet.

This engine has a reputation for failed EGR valves which are part of the emissions control system and live within the rocker cover. Without this valve working properly, the car’s tailpipe emissions can be higher than they should be, as well as causing the oil leak you’ve noted. And any time you have oil hitting a hot exhaust system, there’s the potential for a fire.

In some cases you can simply change the EGR valve, but experience suggests that with some engines, the solution is to replace the entire rocker cover which will incorporate a new EGR valve. The parts can usually be bought online.
