Disconnect the wiring harness from the side amplifier, unscrew the mounting bolts and remove the side amplifier (Fig. 1).
Using a 13 key, we unscrew the bolt securing the clamp holding the automatic transmission cooling hose.
From the bottom with a head of 13, we unscrew the bolt securing the collar of the automatic transmission cooling hose flanging.
Let's move the automatic transmission cooling hose to the side for access to the hydraulic distributor cover (Fig. 4).
Using the TORX T30 wrench, unscrew the four bolts securing the hydraulic distributor cover (we try not to break the edges of the bolts, you can tap before unscrewing).
Unscrew the bracket with a 10 head.
Remove the valve cover (you need to be careful, oil may leak).
