disconnect the transmission external harness from the retarder
connector. If used, disconnect the tachograph or speedometer cable
from the port on the rear of the retarder housing
— For 3000 Product Family transmissions built beginning in January,
1998, disconnect the wiring harness from the retarder temperature
thermistor, the output speed sensor, and the retarder valve body
connector. If used, disconnect the tachograph cable from the port on
the rear of the retarder housing (refer to Figure 3–2).
— For the 4000 Product Family transmissions, disconnect the retarder
connector, the retarder temperature sensor connector, and if used, the
tachograph cable (refer to Figure 3–1).
4. If a PTO(s) is used, disconnect the PTO(s) wiring harness.

— PTO hydraulic hoses
— PTO-powered equipment drive shaft
3. If transmission mountings support the rear of the engine, place a jack or
other support under the engine.
