Jeep Winches: Transmission PTO Adapter
Most heavy duty transmissions have PTO ports onto which a PTO
adpater can be bolted. Some examples of transmissions with PTO
ports include the T-18, T-19, NP435, NV4500, SM465, and SM420.
The PTO adapters I've seen all have a front and rear output.
Since these transmission PTO adapters are driven off of the
countershaft, their speed and direction is not effected by the
gear that the transmission is in. Only engine RPM can be used
to change the speed. Normally, the PTO is only used with
the transmission in neutral.

output. The unit can also be mounted so the shaft is high or low
and the shift lever can be mounted on either side.
