One of few choices, either park it in sun, with hood up as much as you can for a day or 2, and see if that helps or, start pulling connectors off around transmission, & throttle body area, & spray them & components with contact cleaner where they come together, and add di-electric grease to each when re-attaching. One other would be to get air nozzle & compressor & start blowing all around those connectors, as many as you see, and can reach, and you may get lucky.

It sounds like you have a gasket leak. It needs to be checked by a mechanic!
