Tired of tripping over these things.
Auto Trans - $100
NP 231 - $50
Torque Converter - $10 (free with trans)
Take the whole thing for $120
Came from an older lady's vehicle. 133,000 miles. Drained the fluid, no gritty bits, nice and red, looked good to me.
I do have the linkage to these things too, it's still in the XJ though. Some other parts are also available from the vehicle.
