Why is 1993 Jeep stuck in overdrive?
you need to try and get codes out of the Transmission Control Module (TCM). The lamp in the Overdrive OFF switch is used to signal the various flash codes. To view flash codes, proceed as follows: # Turn ignition key ON-OFF-ON-OFF-ON finally leaving the key in the ON position. Leave the Overdrive OFF Switch in the normal overdrive (ON) position. # Immediately begin counting the number of flashes displayed by the Overdrive OFF Switch indicator lamp. # Flash codes will correspond to Powertrain Control Module codes in duration and spacing. # A code 55 identifies the end of flash code transmission. And the possible codes are: * 11 No Engine Speed Sensor Signal * 12 No Output Shaft Sensor Signal * 13 No Vehicle Speed Sensor Signal * 14 Governor Pressure Sensor Signal * 15 Throttle Position Signal * 16 Transmission Temperature Sensor * 17 Overdrive Off Switch Circuit * 18 System Voltage Out of Limits * 19 Standby Voltage Out of Limits * 21 Governor Pressure Solenoid Circuit * 22 3-4 Solenoid Circuit * 23 Torque Converter Clutch Circuit * 24 Overdrive Off Lamp Circuit * 25 EEPROM Checksum Error * 26 Governor Pressure Sensor Offset Drift * 55 End of Message If you still get no codes, then we have to explore a mechanical problem inside the transmission. Possibly the overdrive solenoid not venting or a lower valve body malfunction.
On a 1994 Mazda 626 How do get the button on the shifter to switch back over to automatic from overdrive it is stuck in overdrive and when you push the button it won't switch back?
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
I tow an 18.5' Bayliner with a 2004 Grand Cherokee Freedom Edition 4x4 with a 4.7 H.O., tow pkg. and heavy duty cooling pkg. The boat is considerably under the rated tow capacity but I always turn off the overdrive especially going up and down hills. Jeep recommends to do so if you are towing and the overdrive is constantly kicking in and out; if you do not you will burn out the overdrive unit…
