Flashing OD light. why?

My OD light now flashes. started out it would be every once and a while. Now I see it every day. If I go in reverse with a small trailer it seems to make it blink. it will go off after about 2 min. sometimes i'll hook a trailer up, put it in park and it'll rev up to 1,000 for a sec then go back down. OD light comes on. Do I need a flush? I have an external filter. maybe thats plugged. any ideas?

When I bought the truck they charged me for replacing 2 speed sensors. I did know my truck had 2 of them. but they are supposed to be new.

I thought the vss sensor would cause the abs light to do it's thing?

OD light flashing? Tranny codes... IMO, somethings going south (transmission wise).

There is no abs light on. I ruled the speed sensor out because of that.
