I tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my ford explorer. it wont move forward or
reverse, engine is good both solenoids for forward and reverse work.
I don't have much technical knowledge but I just followed it step-wise, and works perfect! got it from www.reliable-store.com

1. Before servicing the vehicle, refer to the Precautions Section.
   
2. Remove the transmission.
   
3. Drain the engine oil.
   
4. Disconnect the engine oil temperature (EOT) sensor electrical connector.
   
5. Remove the nut and the starter wiring harness support bracket.
   
6. Remove the nut and position the transmission oil cooler lines and bracket aside.
   
7. Remove the 16 bolts and lower the oil pan onto the crossmember.
   
8. Remove the 3 bolts and position the oil pump screen and pickup tube into the oil pan.
   NOTE Be careful when removing the oil pan gasket. It is reusable.
9. Remove the oil pan and the oil pump screen and pickup tube.
   
10. Inspect the oil pan gasket for damage. If damaged, discard the oil pan gasket and the oil pan-to-oil pump gaskets. Discard the oil pump screen and pickup tube O-ring seal.

To install:
WARNING Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

1. Inspect the oil pan. Clean the mating surface for the oil pan with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
   
2. Position the oil pump screen and pickup tube in the oil pan and position the oil pan into the vehicle.
   WARNING Make sure to install a new O-ring seal. A missing or damaged O-ring seal can cause foam in the lubrication system, low oil pressure and severe engine damage.
   NOTE Clean and inspect the mating surfaces and install a new O-ring seal. Lubricate the O-ring seal with clean engine oil prior to installation.
3. Position the oil pump screen and pickup tube and install the bolts.
   
4. Tighten the oil pump screen and pickup tube-to-oil pump bolts to 10 Nm (89 inch lbs.).
   
5. Tighten the oil pump screen and pickup tube-to-spacer bolt to 25 Nm (18 ft. lbs.).
   NOTE If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
   
6. Apply silicone gasket and sealant at the crankshaft rear seal retainer plate-to-cylinder block sealing surface.
   NOTE If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
7. Apply silicone gasket and sealant at the engine front cover-to-cylinder block sealing surface.
   
8. Install the oil pan gasket and the oil pan and loosely install the 16 bolts.
   
9. Tighten the bolts in 3 stages, in the sequence shown.
   Stage 1: Tighten to 2 Nm (18 inch lbs.). Stage 2: Tighten to 20 Nm (15 ft. lbs.). Stage 3: Tighten an additional 60 degrees.
   
10. Install the wire harness bracket and the bolt. Tighten to 10 Nm (89 inch lbs.).
    
11. Position the starter wiring harness support bracket and install the nut. Tighten to 10 Nm (89 inch lbs.).

YOU MAY NEED TO UNHOOK MOTOR MOUNT BOLTS, AND RAISE THE ENGINE JUST HIGH ENOUGH TO CLEAR THE OILPUMP PICKUP TUBE, AND THE CROSSMEMBER, BUT YOU WONT HAVE TO DISCONNECT THE TRANNY!

Remove oil pan oil pump and pick up tube & screen will be bolted on.
You should get oil pump lube, carb. cleaner, new pump oil,
oil pan gasket, silicon, oil & filter, loc-tight, gasket remover & tools metric, 1/4 drive socket set, scraper / putty knife, 2 jack stands, a jack or ramps,
& blocks for rear wheels.
Lets get started.

(1)Get your car up on stands or ramps block rear tires.

(2)Drain oil & remove oil filter remove battery cable NEG (-)

I hope this works for you it's a basic oil pump change for most cars.
Some take more steps.

you may be able to get it off by removing the oil pump,

support front of vehicle, drain oil and return to oil recycling center (walmart) remove both (right and left) motor mounts and transmision linkage, transmision support bars( if needed for extra clearance ) unbolt oil pan. carefully lif engine from frame, taking care not to hit and break anything when the engine gets too close to your firewall. you should then be able to remove and replace oil pan. you'll need the bolt tightening pattern and torque specs for your vehicle. hope this helps

your going to have to remove motor mount bolts and jack motor up in order to get pan off. also after pan is hanging reach inside and unbolt oil pump and pick up screen to get enough roomto remove, hope this helps.
