Having trouble going into 4 wheel drive in a 1998 ford ranger xlt


The transfer case (7A195) is equipped with a magnetic clutch, similar to an air conditioning compressor clutch, which is located inside the transfer case adjacent to the lockup sleeve. The clutch is used to spin up the front drive system from zero to vehicle speed in milliseconds. This spin-up allows the shift between 2H and 4H to be made at vehicle speeds listed in the vehicle owner's guide. The spin-up engages the front lock hubs. When the transfer case rear and front output shaft reach synchronous speed, the spring-loaded shift collar mechanically engages the mainshaft lockup hub to the chain-drive sprocket and the magnetic clutch is then deactivated. Shifts between 4H and 4L can only occur with the transmission safety switches closed. The vehicle's speed must also be within specified limits as determined by the Generic Electronic Module (GEM).
The electronic shift control system consists of a rotary switch control system, a GEM, a transfer case shift motor (7G360) with an integral shift position sensor, a clutch pedal position switch or digital transmission range (DTR) sensor, and a brake signal input switch.
There is a control switch located on the instrument panel for fingertip shift control.

Switch Control System
When the switch on the instrument panel is turned, there is a one second delay, then the electronic control module verifies the transfer case positions (2H, 4H or 4L). Next, the GEM looks at the shift position sensor and the digital transmission range (DTR) sensor or clutch pedal position switch (depending on transmission type) and brake pedal switch. If all conditions are correct to allow the desired shift, the electronic control module will tell the transfer case shift motor to execute the shift. After the shift has been made and the transfer case shift motor is off, the control module again looks at the shift position sensor to make sure the proper shift has been accomplished. Finally, the dash indicator light on the control panel will be illuminated by a signal from the GEM indicating the desired shift has been completed.
GEM
The generic electronic module controls the operation of the transfer case in response to inputs to the rotary control by the vehicle operator, the shift position sensor, the transmission range sensor and the brake pedal switch.

Vehicle Speed Sensor (VSS)
The vehicle speed sensor (VSS) (9E731) generates an AC signal which is sent to the instrument cluster (10849). The signal is used as input to the powertrain control module (PCM) and the transmission control module (TCM).
Shift Position Sensor
The shift position sensor, an integral part of the electric shift motor, tells the GEM module the shift position of the transfer case.
Electric Shift Motor
The electric shift motor, mounted externally at the rear of the transfer case, drives a rotary helical cam which moves the 2W-4W shift fork and 4H-4L reduction shift fork to the selected vehicle drive position.

does it jump out of gear or just doesn't go into gear in the first place ?
  • 4-Wheel Drive Transfer Case Jumps Out of Gear
  • Incomplete shift linkage travel.
  • ADJUST linkage to provide complete gear engagement. ADJUST shift gearshift lever boot.
  • Loose mounting bolts.
  • TIGHTEN mounting bolts.
  • Front and rear driveshaft slip yokes dry or loose.
  • LUBRICATE and REPAIR slip yokes as required. TIGHTEN flange yoke attaching nut to specifications.
  • Internal components.
  • DISASSEMBLE transfer case. INSPECT sliding clutch hub and gear clutch teeth for damage. REPLACE as required.

Ford trauras trouble code 732 - was told transmission code 732 was being produced, what does a code 732 say?


P0732 FORD - Incorrect Second Gear Ratio
Transmission in second gear and the ECM detected an incorrect gear ration. This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.


Hope helps.

Please,can you help me fix cods problems p0732,p0734 on my 2006 Mazda Tribute


P0732 - Improper Ratio for Second Gear.
P0734 - Improper Ratio for Fourth Gear.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as follows:

Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from ECM C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd and 4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

This malfunction will be caused when shift solenoid valve B is stuck open.

Gear positions supposed by TCM are as follows. In case of gear position with no malfunctions: 1 , 2, 3 and 4 positions In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear position above.

Symptoms: Engine Light ON (or Service Engine Soon Warning Light)

Diagnostic trouble code A/T 2ND GR FNCTN with CONSULT-II or P0732 without CONSULT-II is detected when A/T cannot be shifted to the 2nd gear position even if electrical circuit is good.

Possible Causes:
- Shift solenoid valve B
- Each clutch
- Hydraulic control circuit

Change cam position sensor chy


  1. Disconnect the negative battery cable.
  2. Detach the electrical harness connector from the camshaft position sensor.
  3. Unfasten the camshaft position sensor mounting bolt. There is a hole in the bracket for tool access to the sensor mounting bolt.
  4. Rotate the sensor away from the engine block.
  5. Pull the camshaft position sensor up out of the chain case cover. Do not pull on the sensor wire.
There is an O-ring on the sensor case. The O-ring may make removal of the sensor difficult. A light tap on top of the sensor prior to removal may reduce the force needed for removal. Inspect the O-ring for damage and replace if necessary.
To install:
If the sensor removed is going to be re-installed, clean off the old spacer on the sensor face. A new spacer must be attached to the sensor face before installation. If the sensor is being replaced, be sure that a paper spacer is attached to the sensor face and an O-ring is positioned in the groove of the new sensor.
  1. Apply 1-2 drops of clean engine oil to the O-ring prior to installing the sensor.
  2. Install the sensor into the chain case cover and rotate into position.
  3. Push down on the sensor until contact is made with the camshaft gear. While holding the sensor in this position, install and tighten the mounting bolt to 10 ft. lbs. (14 Nm).
  4. Attach the electrical harness connector to the camshaft position sensor.
  5. Connect the negative battery cable.

What is the location of the neutral safety switch on a 2001 Saab 9.3 convertible. Is it a difficult repair with the right tools.


I'm not sure what you mean by "neutral safety switch". I have the shop manual for this car (I also have a 2001) and there is nothing listed under "neutral" or "safety" or "switch" in the index that looks like it.
