Does anyone know where the vacuum line coming from the vacuum modulator on the transmission goes to?



Mine is broke and I dont know where to run the new line.



Thanks Joe

Unless someone has installed a 400 trans and different engine too, 81 and up Grand Wagoner had 360 engine 727 trans and quadra tract transfer case.until 94 and they used 42 re and 46 re transmission????

right, there's no vac modulator on jeep transmissions. or are you referring to the transfercase shift motor (vac operated shift motor to shift bet 4wheel-drive to 2wheel-drive or vice versa. IIRC the vac line is connected to a selector switch in the shifter console and the switch is connected to a vacuum tank.
