Tiffin Allegro Breeze 28BR Transmission Yellow Light On

[cobrasabre1]

Recently purchased my first Tiffin RV (2011 Allegro Breeze 28BR with 55k miles) and the yellow Transmission Idiot Light turned on. What does it mean? How do I resolve/repair the problem? And how do I turn off this light on the dash. Any advice would be greatly appreciated…
