Will an terra bolt up to the engine without a problem? I changed the transmission filter and fluid around a year ago. The fluid looks fine.I think the radiator is the original. I am not the first owner. I've had it for 7-8 years. The only thing I've replaced was alternator, starter, brakes, plugs, plug wires, transmission filter, fluid, and oil. It runs great!

My pathfinder wasn't slipping what so ever. I was driving it down the road with no noise, no slipping, it just quit pulling. It doesn't even try to move no matter what gear it's in. It has 238,147 miles on it and I've never had any problems out of it. Is the transmission shot you think? I'm having a hard time locating a used 2x2 automatic transmission around Harrison,Tennessee.
