The Idiots' Garage: Jeep Transmission Part 1
Craig and Danny attempt to install a new governor pressure sensor into a
1997 Jeep Grand Cherokee Laredo. Hilarity ensues as the due ponder why
transmission fluid looks like something out of a slasher film, whether Lee
Iaccoca is still dead, and why you can never trust the guy behind the parts
counter at the Chrysler dealership.

The procedures presented here are specific to the Jatco Nissan Sentra CVT
transmission. However, these procedures can be effected on any CVT, with
the difference being the pressure ports change. Any service manual, will
show you the proper ports for the CVT you're working on.
Your first tool of choice, is a high pressure gauge, or high pressure
electronic transducer. You can also use an oscilloscope, or even better, a
graphing multi meter to record the pressure waveforms. Finally, we'll also
present a little known device, but with great usefulness. It is called, a
duty cycle controller circuit. These duty cycle circuits are now sold at
many electronic houses, and can be used to control any electrical solenoid.
Most, but not all of them, have variable voltage settings. In our case,
we'll use 12 volts.
Assuming you'll be using a pressure gauge, use the diagrams seen here, to
connect the gauge. Start the engine, and raise the vehicle up in the air,
using a shop lift. If not using a lift, do not go under the car with the
engine on. Remember that each time we change to a different pressure port,
we have to turn the engine off, since the ports are ... Get the whole story

How to adjust bands and change automatic transmission fluid
This is a demonstration of how I tightened the bands of my automatic
transmission and changed the transmission fluid and filter. The vehicle is
a 1998 Dodge Ram 1500 4X4 with a 46RE transmission. This repair was done
after a transfer case repair which required removal of the propeller
shafts. With the front shaft out of the way, access to the front band
adjustment screw was better than normal. It is possible to do this with the
shaft in place, but access for demonstration is not as good. For details of
how the propeller shaft is removed, see my other videos on repairing a
Dodge transfer case oil leak.
Note that the details of how this is done, especially the torque settings
and the number of rotations backward after ideal torque, are very specific
to the 46RE transmission. Be sure the locknut is backed off enough that it
doesn't bottom out when the adjustment screw is tightened. Before ever
doing this type of procedure yourself, you should consult the dealers
repair manual and verify the specific procedure in your car.
This is an amateur demonstration done for entertainment purposes only. The
information offered here is given in good faith but with no guarantees of
accuracy or safety. Any misadventure you encounter if you decide to do
maintenance on your own vehicle is your responsibility.
