Transmission pump possibly it says in the link. You need a transmission expert.

..

The E means that it is electronic and has a transmission control module. That module is matched to the transmission and the ECM. It wont work;.

1. Remove transmission oil pan (be careful oil will splash all over)
2. Remove all bolts slowly, so oil will drain slowly
3. Transmission oil pan gasket is reusable
4. Clean oil pan and let transmission oil drip then reinstall pan and gasket.(At the same time you can change the transmission oil filter.
5. Fill with transmission oil fluid (see specification) 4 liters Dexron4 fluid
6. Start the engine place transmission lever to park or neutral
7. At the same time remove plug (see pictures ) until fluid comes out the transmission plug hole. (replace the plug)



Hope it helps.

looks like a tough job ahead

taking the sump off ?...motor in the engine bay

could try undoing plenty and lift the body up

if you cant get clearance under neath with motor in the engine bay
motor will have to come out


if trying with motor in the engine bay
lots of drive train in the way ..
undo engine mounts
support the motor .... even lift motor a bit
for clearance from steering gear and chassis ,suspension etc
to get the sump off



cant tell if it covers AWD

To remove the engine oil pan either the engine has to be lifted all the way off of the motor mounts and the oil pan should just clear the flex-plate and transmission, or the front axle dropped down out of the way, or the transmission and flex-plate will have to be removed.

Usually if the engine can be lifted enough to fit a piece of 2x4 wood between the motor mounts and the frame then the oil pan will usually just have enough clearance to be removed from the rear and the oil pan should just clear the transmission and the flex-plate. Also, be sure to check that the fan blade does not damage the fan shroud when lifting the engine.

Let me know if you require any further assistance.

I suspect you have had an oil pump failure. To get at the rotory gear oil pump you will have to drop the oil pan. After you take the pan off, ( having drained the oil the oil pump is what the oil pick up line leads into. That pick up assy. is a round shaped disc with a screen inside it. Clean the screen first then the oil pump. Install new oil pan gasket on reassembly. Hope that helps you. Please let me know.

Hopefully the engine was not damaged when the pump broke. If it was you may need a complete engine rebuild, MAYBE.

oil pump is located behind front timing cover..need to drop ol pan and remove front cover to gain access to oil pump

Remove motor mount bolts and rear transmission crossmember bolts or nuts,suppport engine/trans. see if u have enough clearance between pan and axle remove pan. if not, split the exh away from the manifolds. worth a try

they used 2 different transmissions eighther a 4L60E,or a 4L80E you can usualy tell by the amount of bolts in the pan check with local autoparts dealer for exact number each has

the pan under the motor is the oil pan. you can see the oil filter to the left of it (driverside). The plug is in the rear of it facing the back of the truck. On my 6.0l V8 the exuast pipe is rite behind it so when you loosen it have the drip pan ready to catch the oil as it will stream out fast at a wierd angle due to its location. The pan behind it is for the transmission.
