Hope someone can help. after 250K miles, everything is going. 97 pathfinder SE 4WD has new radiator, steering bushings and repair the leak that ate the bushings, transaxle, boots, brake pedal and cruise control plastic thingys, timing belt, water pump, main engine seal, rotor and coil, tune up, brakes, tires, shocks,distributor cap and headlights. I'm sure I've forgotten something.
All repairs were done by good mechanics, except the distributor work which was redone by a good mechanic.
On road trip in ice and snow, the car was getting 10 mpg when normal is 20+. Did not realize I had lost OD until 3rd gear went. Car would rev up but not gain speed above 40. Eventually it went down to 25 mph but made it to tranny shop. Low transmission fluid. No contamination in fluid. Rebuild transmission. There were damaged clutches. Experienced mechanic put it back together, took it for test drive and it was doing the same thing. Said in all the ones (this model nissan transmission) he's done this has never happened. Took it back to shop. Now it won't start. Nothing. No click. He tried disconnect the battery, no go.
Any suggestions?
