Your throttle body may be carboned up and need to be cleaned! This can cause all sorts of idle and hesitation problems. This is caused by the throttle plate not seating properly. The First thing i would do is clean out the throttle body with some throttle plate and intake cleaner and a small brush. Another common cause would be the Idle Air Control motor. This is very common on older cars. The IAC motor gets lazy and cant keep up with the fast idle changes. Also when the IAC motor is out, I rec to check the passages for carbon build up. If they are plugged they need to be cleaned out.

Also U might have an air or a vacuum leak. This is very common! Open the hood and listen for a hissing sound when the engine is running. If it is hard to pinpoint take some break cleaner or starting fluid around the intake manifold and vacuum lines and see if the engine stumble or if the idle is affected. Be extremely careful when doing this!

Check for the following conditions:

Poor connection at PCM or IAC motor. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection. Refer to Diagrams.
Damaged harness. Inspect the wiring harness for damage.
Restricted air intake system. Check for a possible collapsed air intake duct, restricted air filter element, or foreign objects blocking the air intake system.
Throttle body. Check for objects blocking the IAC passage or throttle bore, excessive deposits in the IAC passage and on the IAC pintle, and excessive deposits in the throttle bore and on the throttle plate. Check for a sticking throttle plate. Also inspect the IAC passage for deposits or objects which will not allow the IAC pintle to fully extend.
Vacuum leak. Check for a condition that causes a vacuum leak, such as disconnected or damaged hoses, leaks at EGR valve and EGR pipe to intake manifold, leaks at throttle body, faulty or incorrectly installed PCV valve, leaks at intake manifold brake booster hose disconnected, oil filler cap, oil level indicator loose or missing.

Governor Pressure exceeding recomended pressure will cause the transmission not to shift into 4th gear...I would replace the Governor Pressure Sensor and Solenoid and the Overdrive/Lock-up Solenoid in the transmission

Trany goes to 20mph then you gotta hit the gas to3000rpms then let off the gas for it to shift

1999 I believe these use a Throttle position cable to communicat to tranny what the throttle position is so that it shifts at proper rpm's depending on light throttle or WOT and to enable teh tranny to shift down when going to WOT in order to pass.
It sounds to me like your cabel coudl possibly be broken or disconnected. I woudl check that first,

44re 1999 durango won't start from start easily. High RPM and SLOW start (like not in 1st)

the second code is govener pressure sensor. the pressure is to low. the first code is sensor voltage to low, i would check the wiring where it plugs into trans for corrosion. also make sure the kick down cable on the throttle is connected and not broke because this cable controls the line pressure.

My 1999 Dodge Durango all of a sudden will not shift out of 1st gear and is consequently eating up tons of gas. Can you help me fix this problem?

Have your mechanic check your map sensor and your vehicle speed sensor as they could possibly be the cause.

Runs first gear to max rpms before shifting.

You probably have a bad governor pressure sensor and solenoid.The pressure sensor is what normally goes bad ,but from vast experience,i replace both of them together and change fluid and filter.

I had someone back into my 1999 dodge durango and the hit the cooler it isn't leaking can I drive it without damageing the engine or trandmission.

hit the front end i presume , so yes you can drive it if it isnt leaking. just make sure nothing will fall off when you drive it. if the fins on the front are smashed you might run it hot but itll still be okay for a few miles.
