Note: Do not undo screw "C".





7. Undo fastening nuts for front transmission, support and unscrew the studs.
8. Carefully lower the transmission out. When doing so, avoid damaging the coolant pipes.

Installation
Install in reverse order, observing the following points:





1. Carefully lift in the transmission with a universal transmission jack. When doing so, do not damage the coolant pipes.
2. Push studs through the front transmission mounts and screw into the front-axle cross member.
3. Fasten transmission mounts on the front-axle cross member and on the body.

Note: If the hexagon-head bolt (M10 x 90) was undone on the rear transmission support/ transmission mount, it is important to tighten the front transmission support first, then the rear transmission support and the M10 x 90 screw on the rear transmission mount last.
