Codes and diagnostics

Codes:


Pick two transmission codes out of repair information, and describe what the code means and what mailfunction would cause the code:


Code: LR Solenoid Valve Open


Code:OD Solenoid Valve Open


Diagnosis:


For each code listed above, discuss what tests you could run to diagnose the problem.


1st problem testing:
With the vehicle stuck in 3rd gear, we tryed shifting the car into a different gear. But because all the solenoid valves were stuck open and wouldn't close, the vehicle would not shift and it stayed in 3rd gear.


2nd problem testing


For the 2nd test, we plugged the solenoid cable back into the transmission and turned the car on. We were then able to change up and down gears. We then used the scan tools to make sure the valves were closing when we changed gears and they did.
