I have one of these in my '89 2.6 The transmission is getting close to 240K miles. What is the longevity on these units? It was maintained by the previous (original) owner. I changed the filter and a gallon of fluid about 20k miles ago. Fluid looked clean and not much clutch material in the pan. I'm thinking about possibly removing the trans this summer and replacing the clutch discs before failure. I do occasionally tow about 2k lbs behind the old girl. If these things last to 300k miles regularly, I wouldn't bother. If they normally have given up the ghost by now, I'm on borrowed time.
