Nissan

My 1994 nissan pickup truck rear whl. drive auto trans. slips when in overdrive.somebody had experience or answer to the prob question details:we have flushed, changed the fluid, changed the filter with no change to the problem. the trans shifts & works fine unless the overdrive is selected thanks dh

Your overdrive clutches are going out and changing the fluid will just speed up the process if it hasnt been done reguarly in the past! did you find a lot of shavings in the fluid when you changed it?
