I recently replaced my fluid andtransmission filter. I took it for a spin latter that day and the A.T oil temp light came on. I pulled over instantly and relized I had not tightened my drain plug. I tightened the drain plug and topped my fluid off where it had leaked out. Everything seems fine ,but my light will not go off. I have unhooked battery cable hoping it might reset and still right when I crank it up the light comes on. Any sugestions ??????
