Ford vehicles equipped with 4R70W and AODE units may suffer delayed engagements and burnt forward clutches due to low line pressure. This can be even more pronounced in heavy-duty or performance vehicles. Installing Sonnax elevated pressure main pressure regulator spring 76948-06 eliminates these concerns by raising base line pressure to securely engage clutches.
