Thanks I knew it had to do with tranny I hardly use the OD because it keep downshifting and cherping the tires as it does this. I got under and cleaned up the connecters a little they had dirt (mud) buildup from off roading a short time after that the light went out has'nt come back on since. I sill think there is a problem though it really struggles when in OD so I'm not going to use it anymore till I find out for sure. Thanks for the info guys
