Re: LS SWAP 4l60e problems
The EPC Solenoid Does control Line Pressure through the Torque Signal Circuit that runs to the Boost Valve. In a twist the EPC gets its oil from the Actuator Feed Limit (AFL) Valve, The AFL gets its oil from Main Line pressure.
The AFL valve also feeds Both Shift Solenoids, 3-2 down shift, & TCC PWM solenoid NOT directly by the EPC.
The EPC does wear, But usually in the first 20,000 miles then levels off after that. EPC solenoids have been known to last a million miles & more.
The AFL valve & TCC PWM Isolator/TCC actuator valve assembly is BAD to wear the valve body.
