Have a tranny problem and live in a part of the country where I cant drive to a shop to fix the problem without a huge hassle so I'm trying to find what or where the problem may be. Took the Van out one day and suddenly lost all power in the tranny. Changed the filter and fluid, didn't help, no change. When its cold it seems OK, foward and reverse catch quickly, when it warms up it just quits. My question Is there a fluid pump that may be causing the problem or a fix that would'nt require removing the tranny?
