Maybe it’s not the torque converter!

The Sonnax parts listed here correct transmission problems which are to blame for a variety of torque converter complaints. Many of these parts also can prevent damage to newly installed converters, making them key components in a quality rebuild. Always ask for GENUINE Sonnax parts!

Understanding the connection between transmission components is critical when building a healthy unit or diagnosing a problem one.
