Product Description
Sonnax part number: 104740-32K
Services Two Vehicles
The OE thermal bypass element in GM 6L80 and 8L90 transmissions is prone to sticking open or closed, restricting cooler flow and leading to transmission overheating and damage. Sonnax cooler bypass eliminator kit 104740-32K replaces the OE thermal bypass element, allowing continuous fluid flow through the cooler circuit and removing the risk of sticking or failure associated with the OE element.
- Specially designed plug delivers reliable cooler flow and stable operating temperatures in all conditions
- Integrated O-ring provides a positive seal to prevent leaks
- Drop-in Zip Valve™ parts install quickly and easily — no reaming or special tools required
Symptoms
- Loss of cooler flow
- Overheated transmission
- Overheated converter
- Converter shudder & failure
- Repeated clutch failure
Cause
Poor design of the cooler bypass element coupled with debris and varnish buildup in the OE housing can cause the element to get hung up, restricting cooler flow.
Correction
Restore continuous fluid flow through the cooler circuit by installing drop-in Sonnax cooler bypass eliminator kit.
