Allison 29546972 Pressure Switch Assembly

Install the Allison 29546972 Pressure Switch Assembly to your 2001-2019 GM 6.6L Duramax and get an OEM replacement component. The Pressure Switch Assembly checks the shift valve position in the hydraulic valve body to the transmission control module (TCM) and switches closed when fluid pressure is present. As a result, the assembly allows the transmission control module to receive the ground signal. For the transmission control module to function properly and perform tasks like shifting, the switch assembly is essential for appropriately relaying current information. 

If your Allison transmission Is having shifting issues or trouble codes recommend a switch replacement, your pressure switch may need to be changed. The pressure switch can fail due to high mileage, incorrect transmission fluid, or improper maintenance practices. Made to stringent specifications, this switch is manufactured from quality materials. Ideal for maintaining a factory ride, this part is a direct-fit replacement.
