Hello, my name is ***** ***** I will be glad to assist. Please allow me a moment to gather some information.

ok, thanks

no, it has nothing to do with the transmission. it is an evaporative system control issue. you have a leak in the system and when it is large enough, it will light that warning.

the system needs to be smoke tested to find the failure. the vent solenoid is a common failure but the purge solenoid is also common as well.

did the fuel pump resolve the gauge issue??

was there a trans issue prior to this repair???

it sounds like they are guessing
