serial number 7SR01078, 12000 hours on the machine, 3000 Hours since $25000 spent on transmission. machine is used in grain handling. this is all the imformation i have at the moment.
Thanks for the reply. You have offered a clue in your response that would cause me to question the wiring. I am sure you have had problems with mice eating the insulation of farm machines.
Have they every damaged this machine?
This would likely cause the ECM to have codes.
I will be back online tonight (EST US). If you can send me details on the other questions, I can help you more with this problem.
found the code 69 on the ecm flash codes, turns out it does operate normally, just the reversing beaper is on in forward gear
This diagnostic code is recorded if the control detects a ground in the downshift switch. The ground must be present for more than 3 minutes.
Connector contact 12 is for the downshift switch.
Test Step 1. CHECK THE CIRCUIT FOR PROPER OPERATION.
One switch position should show resistance of less than 5 ohms. One switch position should show resistance of more than 5,000 ohms.
Test Step 2. CHECK THE SWITCH
Repair: Repair the harness or replace the harness.
Proceed to test step 3.
Repair: Replace the downshift switch.
Proceed to test step 3.
Test Step 3. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
CID 0621 FMI 02 is present.
Repair: The problem has not been corrected. It is unlikely that the ECM has failed. Perform the previous Steps again. If the cause of the diagnostic code is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
Repair: The diagnostic code is NOT present. The problem does not exist at this time. The initial problem was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.
turns out it is in 1st gear in both forward and reverse and it is a warning beeper in the cab when you select forward
it appears a wire had come off the park brake micro switch, when the park brake alarm is on will this mean that it only has 1st gear
The park brake wire is the cause of the alarm.
The (first gear select) downshift button is stuck down on the lift lever or the wires are shorted to ground. This will cause the machine to drop back to first gear all the time.
If the button is stuck, remove the front cover of the console and disconnect the button connector. If the button is working, inspect harness for short to ground.
The guide I sent you for the downshift switch is how to test for this problem.
NOTE; If the auto-shift button is on and the transmission speed sensor is not working, the transmission will not upshift. Try operating with the auto-shift off and manually select the gears.
