Chevrolet Impala Transmission Filter Kit Guide (1998-2015)
Keep your Impala's transmission shifting correctly by understanding its specific filter needs.
- First, confirm if you have the 4-speed (serviceable filter) or 6-speed (non-serviceable filter) transmission before buying parts.
- Always use DEXRON-VI automatic transmission fluid.
- Choose a kit with a rubber or metal-and-rubber gasket over a cork one for a better, leak-free seal.
- This is a messy but very manageable DIY job for models with the 4-speed 4T65-E transmission.
Is Your Impala's Transmission Filter Serviceable?
Before buying a transmission filter kit, you must know which automatic transmission is in your Chevrolet Impala. This is the most common point of confusion for owners.
- 1998-2011 Models (Primarily 4-Speed 4T65-E): Most Impalas from these years, including the 8th and early 9th generations, use the 4-speed 4T65-E automatic transmission. These models have a transmission pan that can be removed from the bottom of the transmission. The filter is located inside and is designed to be replaced as part of routine maintenance. This is a common and straightforward service. 🎬 Watch a step-by-step filter replacement on a 4T65-E transmission.
- 2012-2015 Models (Primarily 6-Speed 6T70/6T75): Starting in 2012, many Impalas were equipped with a new 3.6L V6 engine and a 6-speed automatic transmission (the 6T70 or 6T75). These transmissions have an internal filter that is not considered a normal service item. The filter can only be replaced by completely disassembling the transmission. For these models, routine service only involves draining and refilling the fluid via a drain plug, not replacing a filter. 🎬 See how to drain and refill fluid on 6-speed models.
Choosing the Right Aftermarket Kit (For 4-Speed Models)
When shopping for a filter kit for your 4T65-E equipped Impala, you'll find several options. The main differences are in the quality of the filter media and, more importantly, the type of pan gasket included.
Brand Tiers:
- ACDelco (Professional Grade): As the original equipment (OE) supplier for GM, ACDelco is the benchmark for fit and quality. Their kits often come with a high-quality rubber or rubber-and-steel-core gasket that provides a reliable, long-lasting seal.
- Wix (Premium Aftermarket): Wix is a highly respected name in filtration. Their transmission filters are known to meet or exceed OEM specifications and are a trusted choice among many technicians. They often provide quality gaskets similar to the OE style.
- Premium Guard & ATP (Standard Aftermarket): These brands offer a cost-effective solution for maintenance. While the filters are generally reliable, pay close attention to the included gasket. Some kits may come with a basic cork gasket, which is more prone to leaking if not installed perfectly. If possible, choose a kit from these brands that includes a rubber gasket, or purchase a high-quality gasket separately.

Frequently Asked Questions
How often should I change my Impala's transmission filter?
For models with the serviceable 4T65-E, a good interval is every 50,000 to 60,000 miles for severe service (like city driving) or up to 100,000 miles for normal highway driving. If you experience any symptoms of a clogged filter, service it immediately.
What type of transmission fluid does my Impala need?
All 1998-2015 Impalas use DEXRON-VI automatic transmission fluid. Do not use older fluid types like DEXRON-III. Using the correct fluid is critical for proper transmission function and longevity.
Can I just change the filter and reuse the old fluid?
No. The service involves draining the old, contaminated fluid and replacing it. The filter change is done at the same time. You will need approximately 7 to 8 quarts of new DEXRON-VI fluid for a pan-drop service.
Are there any recalls or TSBs for my Impala's transmission filter?
There are no specific recalls for the transmission filter itself. However, numerous Technical Service Bulletins (TSBs) exist for the 4T65-E and 6T70 transmissions related to shift quality, shuddering, and internal component failures. A common issue on the 4T65-E is the failure of the pressure control solenoid (PCS), which can cause harsh shifting and is often replaced during a filter service. 🎬 Learn how a DIY transmission service can stop rough shifting. A TSB for some 2015 models addressed a potential flex plate issue, which is related to the transmission but not the filter.
