potentially causing housing cracks it is necessary to
drain the Heat Exchanger when not in use for
extended periods in freezing ambient temperatures.
1. Shut off the water source to the transmission.
2. Ensure proper drainage of water from
transmission prior to proceeding.
3. Using a 3/16” hex key wrench, remove both
1/8” NPT plugs located on the bottom of the 3-
speed casing.
4. Replace the 1/8” NPT plugs once the water has
been drained out.
