Will not drive forward unless winter button is on goes in reverse fine

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your 2000 Honda Passport is playing favorites with the winter button—like it needs a little extra encouragement to move forward! When it only drives in winter mode but not in regular drive, it often points to an issue with the transmission, like a low fluid level, a faulty shift solenoid, or even a worn clutch pack. The winter mode usually alters the shift patterns to provide better traction, which can mask underlying transmission problems. It might be worth checking the fluid level and condition first; if it’s low or burnt, that’s a sign you need to address it.
