I recently got a fault code reader and discovered the following faults in my 2006 MINI:

P0456
Evaporative emission leak (very small leak)

P1787
Transmission ratio control actuator open circuit

P1698
Transmission control module control error

I know that when your car says something is wrong, you should get it fixed as soon as possible. However, I would honestly like to know if these issues, which came up within the past month, are things that need to be fixed RIGHT NOW or if they are things that can wait, and for how long. I don't actually plan to wait long if they are not RIGHT NOW issues. It's just that I have a road trip planned to go to a family wedding at the end of September, and I have a budget. If this will result in expensive repair, I may not be able to make my trip. However, if the car breaks down while I'm on my trip, that would be even worse.

I would appreciate insight on these fault codes.
