GM 4L80-E Transmission Rebuild - Transmission Repair
Here is a full rebuild video of a GM 4L80-E Transmission. We see the parts that took for a successful repair. Complete overhaul kit with clutches and steels and molded pistons. All bushings as well.
There's some items that I personally would've add to the parts list but since this is for a Transmission Shop down the road this is what I was provided with.
Items I would add are:
Actuator Feed limit Valve, Transgo.
TCC Regulator Valve Kit from Sonnax.
1-2 & 3-4 Shift Valve Springs from Sonnax.
TCC PWM Solenoid.
EPC Solenoid.
And Shift Solenoids if needed.
