Thanks for your time.

The 4.0 sohc has much better performance than the regular 6. It has a problem with leaking upper intake manifold gaskets, which usually shows up as rough idle and hard cold start. Parts are cheap - several o-rings, labor is 2 to 3 hours.
That vintage V6 also had problems with the timing chain tensioners. They wear down. They make noise when the engine is first started - it will often disappear several seconds after start. These are pricey to fix. The engine must be pulled to replace the rear tensioners if they are bad. There was a "customer satisfaction" campaign by Ford, and they would replace the tensioners if they went bad in less than 75,000 miles. Not sure if that campaign is still active. A dealer can take the vin and tell you whether that repair was made to the vehicle.
Possibly you will have front hub problems with the auto-engaging hubs. Pricey to replace, many people go to manual hubs to save the $$.
The 5r55e tranny is not as tough as the 4r70w in the V8's. Just do your maintenance - fluid changes per the manual!
