My Pickup, a 1998 Mazda B2500 Auto transmission, all of a sudden started slipping. When I push the overdrive button to turn overdrive off it will go normally, but in reverse it slips. Push the overdrive button to turn it on and it slips bad. This just happend with out warning. Any suggestions?

 

I'd check the fluid level first, you have to check the level with the tranny warm engine idling and in park on a level surface,take a smell if to it smells burnt you prob. have issues
