Wondering if I could get some feedback on an issue I hit. In June or July I received a warning light for my transmission. I panicked and shut the car off. I started it again and it came up for a second and cleared. I haven't seen the error return and no odd shifting. I will say that day was very hot a humid but I'm not sure if that can affect it. Should I be worried? I've been told that it means the transmission will fail and should be replaced or rebuilt. Has anyone seen something similar?

The code is p0702 I've heard it's a very generic code but my worry is spending that kind of money to rebuilt it. It's a good amount that I do not have lying around.

2015 Lancer Evo MR almost 60k miles and I did my transmission service at 30k.

thanks

I would check the wiring for any loose pins, connectors, frayed wiring, etc. as the first order of business.

P0702 Internal control module, monitoring processor system (Malfunction)

 

thanks, they did check that and it checks out okay.
