Transmission Filter Kit Guide for the 1975-1976 Chrysler Valiant
Keep your Valiant's legendary TorqueFlite transmission shifting smoothly with the right filter kit.
- A quality aftermarket kit from a brand like Wix is the only practical option, as new OEM parts are no longer made.
- Symptoms like delayed shifting, whining noises, or a burning smell point to a clogged filter that needs immediate attention.
- Replacing the filter is a messy but manageable DIY job that is critical for the longevity of your Valiant's durable TorqueFlite transmission.
- No recalls were found for the transmission on 1975-1976 models, making regular maintenance your primary defense against failure.
Is Your Transmission Filter Clogged?
A clogged transmission filter starves the transmission of the clean fluid it needs to operate. Ignoring the signs can lead to serious and expensive damage. Look out for these common symptoms in your 1975-1976 Valiant.
- Delayed or Rough Shifting: You might feel a noticeable pause or a clunk when shifting from Park into Drive or Reverse. The transmission may also hesitate or shift erratically while driving.
- Whining or Rattling Noises: Strange noises from the transmission, especially whining that changes with engine speed, can signal that the pump is struggling to pull fluid through a clogged filter.
- Burning Smell: A distinct burning smell suggests the transmission is overheating. A clogged filter restricts fluid flow, which is critical for cooling, causing the fluid to burn and break down.
- Fluid Leaks: While leaks can have many causes, a clogged filter can create excess pressure inside the transmission, forcing fluid past old gaskets and seals.
Choosing the Right Aftermarket Filter Kit
For a classic vehicle like the 1975-1976 Valiant, finding new Original Equipment Manufacturer (OEM) parts is nearly impossible. The original Mopar part (P/N 3515966) has long been discontinued. Fortunately, the aftermarket provides reliable solutions.
Aftermarket is Your Only Option
Don't waste time searching for a new Mopar filter for your vehicle. High-quality aftermarket brands are readily available and are the standard replacement for these classic transmissions.

Frequently Asked Questions
Do I need to know if I have an A-904 or A-727 transmission?
While the filter itself is often the same for both transmissions, the pan gaskets can be different. The Wix kit and others like it often include gaskets for both transmission types. However, it's always best practice to identify your transmission by its pan shape before you begin to ensure you use the correct gasket and avoid leaks.
Can I replace the transmission filter myself?
Yes, this is a job that a DIYer with some experience can handle. It involves safely raising the vehicle, draining the fluid, removing the transmission pan, swapping the filter, cleaning the pan and mating surface, and reinstalling with a new gasket before refilling with the correct type and amount of fluid. Be prepared for a messy job, as fluid will continue to drip.
How often should the transmission filter be changed?
For these older vehicles, a good rule of thumb is to change the fluid and filter every 30,000 to 50,000 miles, or if you notice any of the symptoms of a clogged filter. Regular service is the key to the long life of the TorqueFlite transmission.
Are there any recalls for the 1975-1976 Valiant transmission?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls related to the automatic transmission internals or filter for the 1975-1976 model years.
