SOURCE: Hyundai Overdrive wont engage

It is not suggested strip and twist wires. Better take it to an authorized service station to check what causes the problem.Is it OVERDRIVE SWITCH or CRUISE CONTROL MODULE faulty?
Over drive switch has three points. (5 to 4 selects "ON" or 5 to 6 selects "OFF").
Right click on following schematic, "save picture as" to a location in your PC so you have a ZOOM IN view.

SOURCE: 1997 isuzu wizard mu check light

Code 24 is a vehicle speed signal sensor fault, the sensor most likely does not provide a useable signal until about 25 MPH, when the computer doesn't see any signal after that speed it turns on the light. Make sense?

SOURCE: 93 isuzu bighorn

a temperature sender located at the thermostat housing was found to be faulty sending permanent earth to tranmission making the overdrive gear inoperable . when replaced the vehicle achieves 100kph from 2500 rpm as true.

SOURCE: OD on Auto gearbox goes into neutral when cold

You need to have your transmission serviced. The fluid has gotten so thick in there that it builds up too much pressure and your transmission will either kick it out of gear or blow up. I'm glad it actually still works. Once the oil warms up it thins right out and it works no prob. Just service your tranny, and you'll be fine.

GEARBOX 1995 USUZU MU 3.1 DIESEL

If the clutch is not disengaging when you put your foot on the clutch ( if the system has been bled correctly or cable fitted correctly ) then the problem is that the clutch plate is in the wrong way round and the clutch hub with the springs is hitting on the flywheel bolts

Odds are the problem is inside the transmission.
Could be a bearing or the syncro for 5th gear among other things.

Hi.

There are several faults that may result in the problem. Check the throttle position sensor voltage range. If the TPS is bad the transmission control module (TCM) will not know that you are opening the throttle and will not engage higher gears.
Check the solenoid for the gears that are not engaging. Check wiring from TCM to solenoids and wiring between overdrive switch and module. The transmission shift solenoid are located on the transmission in the valve body.
Check the speed sensor (VSS) located in the transmission.
If all that is OK sk the dealer to scan TCM and ECM (main computer) for issues.
Additionally if the box has been replaced with a used one, then the installed transmission may be faulty. Test all the rest first.

Regards.

Auto gearbox overdrive wont engage oil level ok fiddled with wires on box n thermostat it worked but has stopped again thanks jon

My 94 wouldn't hold it's gears and would drop down and over rev. My problem was the oil. It should be Dexron 2 and some body had put the wrong oil in. It was drained refilled run for a while and drained again, then used for about 2 weeks. Drained it again etc and it's been fine ever since.
Hope this works for you, good luck.
