Customer came in with a common torque converter shudder concern. To correct the issue, we replaced the factory torque converter with a new unit. While the transmission was down , we also installed new valve body pulse dampeners to help improve transmission operation and longevity.
To further enhance reliability and keep transmission temperatures under control, we added a 40K external transmission cooler along with new AN lines and fittings for a clean, high-performance installation.
Work Performed:
* Replace torque converter
* Install valve body pulse dampeners
* Install 40K transmission cooler
* Install new AN transmission lines and fittings
A solid upgrade package to help eliminate converter shudder and improve the overall durability of the 8L90 transmission.
