Replacing a pressure solenoid valve in the transmission valve body may fix an issue where the transmission "hunts" between first and second gears. Our technicians report that customers sometimes describe this complaint as surging or bucking.

If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.
On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
On the 3.9L V6, 5.2L V8 and 5.9L V8 the Oil leaks commonly from the valve cover gaskets, intake manifold gaskets (front and rear), timing cover gaskets, distributor O-ring, and the rear main seal area. Using fluorescent engine oil dye can be helpful in determining the source(s) of the oil leak.
On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.
One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
When driving over bumps a clicking or squeaking from the rear leaf springs may be fixed by replacing the (leaf) spring tip liners and installing a spring clinch clip (kit available from the dealer).
If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.
For the 4x4 models, a high pitched whistle heard between 30 and 60 miles per hour can be caused if the tie rod adjusting sleeve is oriented in a way that the sleeve slot is facing toward the front of the vehicle. Wrapping tape completely the sleeve will allow you to verify the the sleeve is creating the whistle. Rotating the adjusting sleeve so the slot does not face forward will fix the problem.
