Ford CD4E and Mazda LA4A-EL transmissions often develop a leaky end plug at the pressure regulator bore causing line pressure instability, low EPC pressure and ultimately resulting in burnt clutches and bands. Replacing the OE end plug with Sonnax O-ringed end plug kit 73840-06 provides a solid seal to halt TV/EPC pressure loss from this circuit. Drop-in Zip Valve™ parts install quickly and easily.
