The E4OD transmission system has two types of oil pans: a deep pan and a shallow pan. The deep pan is found on 4x4 trucks, while the shallow pan is found on 2WD trucks. The difference between the two is the length of the spout that sticks off the bottom of the filter. The shallow pan has a shorter tube of about half an inch or slightly longer, while the deep pan has a longer tube of about 2-3 inches. The deep pan also holds almost a gallon more fluid than the 2WD pan.

What You'll Learn
The shallow pan is for 2WD, the deep pan for 4WD
The E4OD transmission system has two types of pans: a shallow pan and a deep pan. The shallow pan is for 2WD trucks, while the deep pan is for 4WD trucks. This means that if you own a 2WD truck, you will need a shallow pan, and if you own a 4WD truck, you will need a deep pan.
The main difference between the two pans is the length of the spout or tube that sticks off the bottom of the filter. The shallow pan will have a shorter tube of about half an inch or slightly longer, while the deep pan for 4WD will have a longer tube of about 2-3 inches. This longer tube is necessary to reach the extra depth of the pan.
The shallow pan is typically found on 2WD trucks because it does not need to hold as much fluid as the deep pan. The deep pan, on the other hand, is designed to hold almost a gallon more fluid than the 2WD pan. This additional fluid is necessary for the 4WD system, which has more complex mechanics and requires more fluid to function properly.
It is important to note that while the depth of the pan and the length of the tube are the most noticeable differences, there may be other subtle variations between the two pans. For example, the deep pan may have additional features such as a drain plug, a boss for trans temp, and an O-ring instead of a gasket. These features may not be present on the shallow pan, as they are not as crucial for the 2WD system.

Shallow pans have a shorter spout, deep pans a longer one
When it comes to differentiating between the E4OD deep and shallow pans, one distinctive feature to look out for is the length of the spout. Shallow pans typically have a shorter spout, while deep pans are characterised by a longer one. This difference in spout length is a crucial indicator of whether you have a 2WD or 4WD vehicle.
The shallow pan, with its shorter spout of about half an inch or slightly more, is commonly found on 2WD vehicles. This shorter tube protrudes from the bottom of the filter, and its length is a key distinguishing factor from its deep pan counterpart.
On the other hand, the deep pan is designed for 4x4 trucks and features a significantly longer spout, typically measuring 2 to 3 inches. This extended length allows the tube to reach deeper into the pan, accommodating the increased depth of the 4WD pan.
While the spout length is a defining feature, it's worth noting that beyond this, the two pans may appear visually similar. However, there are other functional differences to consider. For instance, the deep pan can hold almost a gallon more fluid than its 2WD equivalent, which can impact cooling performance.
In summary, when distinguishing between the E4OD deep and shallow pans, pay close attention to the spout length. The shallow pan for 2WD vehicles will present a noticeably shorter spout, while the deep pan for 4WD trucks will offer a more extended tube to accommodate the deeper pan. This difference in spout length is a quick and effective way to identify which pan you are dealing with.

Deep pans have a drain plug
The presence of a drain plug is not the only difference between deep and shallow pans. Deep pans also have a longer spout or extension tube that sticks off the bottom of the filter, which is around 2-3 inches long. The shallow pan has a much shorter tube of about half an inch in length.
The deeper pan also holds more fluid, almost a gallon more than the 2WD pan. This is a desirable feature for some, but others argue that the larger pans do not help oil temperatures, as the oil pump can only circulate a certain amount.
It is worth noting that both shallow and deep pans may or may not contain drain plugs, so this is not always a definitive way to distinguish between the two. Shallow pans are all one depth, whereas deep pans have a step down that covers 3/4 of the bottom of the pan. This change was instituted to allow the transmission to hold more fluid and dissipate more heat.

Deep pans hold extra fluid
Deep pans hold almost a gallon more fluid than 2WD pans. This means that the fluid takes longer to cool. However, some people argue that larger pans do not help oil temperatures. This is because once the oil heats up, the oil pump can only circulate a certain amount of oil to the cooler.
The E4OD has two pan depths: the 4x4 and the 2WD. The 2WD is the shallower of the two. The filter for the 4x4 will have an extension tube to go deeper into the pan. The difference between the filters is the spout that sticks off the bottom of the filter. The shallow one will have a tube that is half an inch long or slightly longer, while the 4WD/deep-pan version will have a 2-3 inch pickup tube.
Some people opt for larger pans because they have a drain plug, a boss for trans temp, and an O-ring instead of a gasket. However, others argue that adding a bigger cooler is better than just having a bigger pan.

Deep pans are more expensive
There are several reasons why someone might opt for a deep pan. Firstly, it has a drain plug, an O-ring instead of a gasket, and can hold extra fluid (almost a extra gallon compared to a 2WD pan). Secondly, it can strengthen the transmission, especially if it is made of aluminium with fins, which cools down faster than a stock steel one.
However, some people argue that larger pans do not help with oil temperatures. Once the oil heats up, the oil pump can only circulate a certain amount of oil to the cooler. Therefore, a larger amount of oil in the pan does not cool off faster.
Ultimately, the decision to choose between a deep or shallow pan depends on various factors, including the specific requirements and budget constraints of the individual.

Yes, you can buy a bigger cooler or a trans pan for a 4r100 as the E4OD/4r100 are similar transmissions.
