Shallow pans are flat on the bottom, deep pans have a stepped bottom
Shallow and deep transmission pans may look similar, but there are ways to tell them apart. Shallow pans are flat on the bottom, while deep pans have a stepped bottom. This step is located towards the front of the pan, facing the engine. You will notice about two inches of a shallow part, then an angle that brings it down noticeably (over an inch) before it continues to the rear of the pan. This step covers about three-quarters of the bottom of the pan.
The depth difference between the two pans is significant. Shallow pans are about 1.5 inches deep, while deep pans are closer to 3 inches deep. This difference in depth allows the transmission to hold more fluid and dissipate more heat.
You can identify whether you have a shallow or deep pan by inspecting your transmission oil pan. Crawl under your vehicle and look at the middle, up by the front wheels. If the pan is flat, it is a shallow pan. If you notice a step, it is a deep pan.
It is important to know the type of transmission pan you have when ordering an oil filter. Both shallow and deep pans may have 16 bolt holes, be painted or unpainted, and may or may not contain drain plugs. However, the difference in depth affects the pump intake, which must reach deeper into the pan for a deep pan. This difference is made up by changing the filter.

Shallow pans are around 1.5 inches deep, deep pans are around 3 inches deep
Shallow and deep transmission pans have distinct characteristics that differentiate them. Shallow transmission pans are typically around 1.5 inches deep, while deep pans are approximately 3 inches deep. This difference in depth is crucial as it determines the fluid capacity of the transmission and its ability to dissipate heat.
Shallow pans are generally characterised by a flat bottom, lacking any significant steps or angles. They are often found in vehicles with specific clearance requirements, such as the need to clear the exhaust Y pipe in V8 engines. Shallow pans usually have a standard depth of around 1.5 inches, providing a compact design that suits particular engine configurations.
On the other hand, deep transmission pans are designed with a step-down feature. This step-down typically covers about three-quarters of the pan's bottom, creating a noticeable angle and a deeper section at the rear. The step-down feature in deep pans allows them to hold more fluid, which in turn enhances heat dissipation. The increased fluid capacity can be advantageous for certain driving conditions or performance requirements.
It is important to accurately identify whether your vehicle has a shallow or deep transmission pan before ordering replacement parts, such as oil filters. While both types may share certain characteristics, such as the number of bolt holes, the presence of paint, or the inclusion of drain plugs, the depth of the pan is a defining factor.
To determine the depth of your transmission pan, a physical inspection may be necessary. Measuring the depth of the pan or comparing it to images or descriptions of known shallow and deep pans can help identify the type of pan in your vehicle. This information ensures that you select the correct parts, such as filters, that are compatible with your transmission's design.

Shallow pans are used on V8s to clear the exhaust Y pipe
Shallow transmission pans are typically used on V8 engines to clear the exhaust Y-pipe. While it is difficult to determine whether a transmission pan is shallow or deep without physically inspecting it, there are some methods to identify the type of transmission pan in your vehicle. One way is to refer to the vehicle's VIN or model information, which may provide details about the transmission pan. However, in some cases, you may need to get under the vehicle and visually inspect or measure the pan directly.
Shallow transmission pans are often characterised by a flat or shallow profile, in contrast to deep pans, which have a more pronounced depth. The depth of a transmission pan is important because it determines the fluid capacity and heat dissipation capabilities of the transmission system. A deeper pan can hold more fluid, which helps in dissipating heat more effectively.
When inspecting the transmission pan, you may notice that both shallow and deep pans share some common characteristics. For example, they typically have 16 bolt holes, and they may be painted or unpainted. Additionally, the presence or absence of a drain plug is not indicative of the pan's depth. However, a key distinguishing feature is that deep pans have a step down at the bottom that covers about 3/4 of the pan, while shallow pans have a uniform depth throughout.
It is worth noting that the transmission pan's depth can impact the type of oil filter required. A deeper pan may require a deeper filter that reaches further into the pan, and it may also have a plastic spacer moulded into the filter. Therefore, it is important to inspect the transmission pan before ordering an oil filter to ensure compatibility.

Deep pans have a step down towards the front of the pan facing the engine
The depth of a transmission pan is important to know when ordering an oil filter. Shallow pans are typically used on V8s to clear the exhaust Y pipe. Deep pans, on the other hand, can hold more fluid and dissipate more heat. This means that the pump intake has to reach deeper into the pan, and so the filter has to be changed.
You can identify whether your transmission pan is deep or shallow by inspecting it. Crawl under the truck, right in the middle, up by the front wheels. If you see a step down towards the front of the pan, it is a deep pan. The shallow pan is completely flat.
It is also possible to measure the depth of the pan. Shallow pans are about 1.5 inches deep, while deep pans are closer to 3 inches deep.

Both shallow and deep pans have 16 bolt holes
It can be tricky to determine whether your transmission oil pan is shallow or deep. However, there are a few tell-tale signs to look out for. Firstly, shallow pans are flat on the bottom, whereas deep pans have a noticeable step down. This step is located towards the front of the pan, facing the engine. From the top side, you will be able to notice the differences in depth between the two styles. Shallow pans are all one depth, whereas deep pans have a stepped bottom.
It is important to know the type of transmission pan you have when ordering an oil filter. Shallow and deep pans may require different filters due to the difference in depth. The deep filter has a thicker filter medium and a plastic spacer moulded into the plastic portion of the filter. Additionally, if you have a shallow pan, you may consider upgrading to a deep pan to increase fluid capacity and improve heat dissipation.
It is worth noting that the year, make, and model of your vehicle can also provide some indication of whether you have a shallow or deep pan. For example, shallow pans were reportedly used on some 2002 and 2003 models, while deep pans were used on certain 2006 and 2007 models. However, there may be variations due to differences in suppliers and parts availability during production. Therefore, it is always best to inspect your transmission pan directly to confirm its style.
