A Guide to the Transmission Filter Kit for the 1992-1996 Jaguar XJS
Choosing the right transmission filter kit is critical, and it starts with knowing which transmission is in your XJS.
- You must identify your engine (4.0L 6-Cylinder or 6.0L V12) to buy the correct filter kit.
- The 4.0L engine uses a ZF 4HP24E transmission, while the 6.0L V12 uses a GM 4L80E transmission.
- For 6.0L V12 models, check if your GM 4L80E has a deep or shallow pan, as this determines the correct filter.
- Aftermarket brands like Wix, ATP, and Premium Guard offer a reliable and cost-effective alternative to expensive OEM parts.
First, Identify Your Transmission
Before you buy a transmission filter kit for your 1992-1996 Jaguar XJS, you must know which engine your car has. The engine determines the type of automatic transmission, and each transmission uses a different filter kit. This is the most common mistake owners make.
- 4.0L 6-Cylinder Models: These cars are equipped with the ZF 4HP24E automatic transmission.
- 6.0L V12 Models: These cars are equipped with the GM 4L80E automatic transmission.
Always verify your engine size to ensure you purchase the correct kit. Using the wrong kit will lead to installation problems and potential transmission damage.
Common Ordering Mistake: GM 4L80E Pan Depth
For the 6.0L V12 with the GM 4L80E transmission, there can be two different oil pan depths: shallow or deep. This affects which filter you need. It is best to visually inspect your pan or, if possible, measure its depth before ordering to guarantee you get the correct filter. Some kits may specify if they are for a deep or shallow pan.
Choosing the Right Aftermarket Filter Kit
For a classic vehicle like the XJS, aftermarket parts offer a great balance of value and quality. The original OEM Jaguar parts can be expensive and hard to find. Aftermarket brands provide reliable alternatives that meet or exceed original specifications. The main differences between brands come down to the quality of the filter material and, importantly, the pan gasket.
Brand Quality Tiers
Tier 1: Premium Aftermarket (Wix)
Wix is a well-regarded brand known for high-quality filtration and construction. Owners often choose Wix for peace of mind, as their kits generally provide excellent fitment and reliable, long-lasting performance. The gaskets included in Wix kits are typically well-made, though sometimes they can be folded in the box and may need to be laid flat before installation.
Tier 2: Standard Aftermarket (ATP, Premium Guard)
Brands like ATP and Premium Guard offer a cost-effective solution that gets the job done. They provide perfectly adequate filtration for regular maintenance. ATP is well-known for its "3rd Hand" pan gaskets, which have small tabs to hold the pan bolts, making it easier to install the pan from below. Premium Guard also highlights its use of quality NBR rubber gaskets designed for a secure fit. These brands are a solid choice for DIY mechanics and those on a budget.
Pro Tip: Gasket Quality is Key
A leaking transmission pan is a common frustration after a filter change. The cause is almost always a poor-quality or improperly installed gasket. While the gaskets in most kits are reliable, some mechanics prefer to use a separate, high-quality rubber gasket if the one included appears to be made of a lesser material like cork. Always ensure the pan and transmission mating surfaces are perfectly clean before installing the new gasket.

Frequently Asked Questions (FAQ)
How do I know for sure which transmission my XJS has?
The most reliable way is to check your engine. If you have the 4.0-liter inline 6-cylinder engine, you have the ZF 4HP24E transmission. If you have the 6.0-liter V12 engine, you have the GM 4L80E transmission. You can also check for an identification plate on the side of the transmission housing, but identifying by engine is usually easier.
Are there any recalls on the transmission filter for my XJS?
No, there have been no recalls issued by the NHTSA for the transmission or transmission filter on the 1992-1996 Jaguar XJS. There was an emissions-related recall in 2001 for some 1994-95 V12 models, but it did not involve the transmission.
What comes in a typical aftermarket kit?
A standard kit includes the transmission filter and a new pan gasket. Some kits for the GM 4L80E may also include a new O-ring or seal for the filter pickup tube.
Can I reuse my old pan gasket?
It is strongly recommended that you do not reuse the old gasket. Gaskets compress and harden with heat and time. A new gasket is included in the kit and is essential for preventing fluid leaks after the service.
