lever engages is not damaged.
The valve is very »sensitive«. Even minor damage leads to mal‐
function.
– Always slide the valve into the body, secure it against falling
out and never exchange it.
The valve body bolts on the transmission housing have different
lengths and must be replaced.

Installing
– Observe correct routing of wires so that they do not get jam‐
med when installing the valve body.
– Route the wiring harness -5- into the transmission as illustra‐
ted.
The distance -a- must be maintained so that the wiring harness
-5- does not touch the planetary gear and get damaged when the
vehicle is being driven.
– The wiring harnesses -1, 3, 4 and 5- lay over the edge of the
transmission as illustrated.
– Attach the wiring harnesses to the transmission with tape.
– Coat the damper piston -2- with ATF and then install it with the
spring into the transmission housing, as illustrated.
– Mount the valve body and install the two bolts hand-tight.
• The wiring harnesses -1, 3, 4 and 5- must not get caught by
the valve body.
