Principles of Operation
Transfer Case - Electronic Shift
The four-wheel drive, electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4X4 HIGH, and 4X4 LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators, one for 4X4 HIGH which is 4X4, and one for 4X4 LOW which is LOW RANGE (in 4X4 LOW both the lamps are on). Shifts into 4X4 HIGH can be made at any speed. When shifting into 4X4 HIGH with the vehicle stationary, tooth blockage may occur, preventing shift completion. When the vehicle is driven above 8 km/h (5mph) the shift will complete. When shifting in or out of 4X4 LOW, the generic electronic module (GEM) requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission). (The digital transmission range [TR] sensor informs the GEM when the automatic transmission is in the NEUTRAL range position.)
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and the range fork within the transfer case between the 4X4 HIGH, 4X4 LOW, and 2WD range positions.
The GEM uses two relays to control the gearmotor encoder assembly shift between 4X4 HIGH, 4X4 LOW, and 2WD modes. The GEM controls the pulse vacuum hublock (PVH) solenoid which supplies engagement and disengagement vacuum to control the hublocks.
The GEM accomplishes shifts by interpreting inputs from:
  • mode select switch (MSS)
  • vehicle speed signal (transmitted from the ABS system)
  • gearmotor encoder plate position
  • brake pedal switch
  • digital transmission range (TR) sensor (automatic transmission)
  • clutch pedal position (CPP) switch (manual transmission)
  • ignition switch
Based on these inputs, the GEM controls the shifts into 2WD, 4X4 HIGH, or 4X4 LOW with the following outputs:
  • low to high relay (clockwise)
  • high to low relay (counterclockwise)
  • pulse vacuum hublock (PVH) solenoid
  • gearmotor encoder assembly
The electronic shift-on-the-fly (ESOF) system has a feature which allows the driver to override the vacuum operated hublocks. When the front hublocks are manually turned to the LOCK position, the hublocks are locked at all times, overriding the vacuum operated system. If the front hublocks are manually turned to the AUTO position, the hublocks can only be locked by turning the MSS to 4X4 HIGH or 4X4 LOW position.

Blew an oil line while driving. replaced it, added oil. car started right up prob is auto trans would not engage in any gear. no previous problem. does low oil press affect the trans??


Blew an oil cooler line or a transmission cooler line? Low transmission fluid would keep it from moving. Trying to drive it to long with transmission fluid about empty, would burn up the transmission. Oil pressure won't affect the transmission.

J30 won't shift gears


When the car was jump started, you may have caused a voltage surge that affected the on-board computer module; and/or the computer module for the transmission.

Another possibility, once you disconnected your battery, you may have disrupted the on-board memory codes- such as the transmission's adaptive settings- so you may have to bring the car to the dealer repair shop or a transmission shop. Even if you take it to a local auto repairman, make sure he/she is an ASE certified mechanic.

I have a 1998 Rodeo and I think the alternator went out however I charged the battery and tried to drive it and it is giving me trouble shifting gears. would the alternator being out affect the...


Sounds more like the alternator is still not putting out 100%...eventually your Izusu will quit running with a defective alternator...please have tested...so you don't get stranded...the battery will only run the car until it becomes low on power...sometimes the first sympton is limited acceleration...ie. can cause auto/shifting to be inconsistent...if high mileage, also consider adding a bottle of Lucas Oil Transmission fix...no draining necessary...excellent results. Hope this helps.

My truck speedometer stays at 0 until about 20 mph. also it stays in low gear too long. 4x4 auto 318.


The two problems may or may not be related. First go to the vehicle speed sensor on the rear axle to see that the wiring and connection is clean and tight to the sensor. If it is all good there then change the vehicle speed sensor, this should fix the speedometer. The Dodge transmission has it's own speed sensor and if it is affecting the shift, it should be storing a transmission code. Also the wiring harness inside the transmission may be faulty.

Where is the battery on a 2003 Thunderbird?


Your battery is located in the trunk of your vehicle.

When the battery is disconnected or a new battery is installed, the

transmission must relearn its shift strategy. As a result, the transmission

may have firm and/or soft shifts. This operation is considered normal and

will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
