I replaced both bulbs (engine oil pressure and transmission) in the gauge cluster. Both were broken. The engine oil press. light comes on when key is turned to on but goes off once engine is running as expected. The transmission light stays on when the engine is running, at least for the three minute test I did today. I added 2 QT of fluid to bring it to exactly full and it still happens. Its warm here in upstate NY (40F) for winter. I guess change the hydraulic filter as the next step?
