Can a CD4E be used in a transmission rebuild?
Along with many other modern units, the CD4E is prime example of the challenges we are faced with in the transmission rebuilding industry. Today’s successful transmission rebuilds require a careful and thorough two-step process. Diagnosis requires finding the cause as well as the failure.
Can a solenoid be replaced on a CD4E?
Experts recommend replacement kits solenoids that deliver the car owner from the need for frequent repair automatic transmission CD4E.

It is for these reason solenoids to replace one is unprofitable.
What is the DTC code for CD4E transmission?
CD4E Code (DTC) P1837 Transmission Transfer Case Rear Shaft Speed Sensor Circuit Failure CD4E Code (DTC) P1838 Transmission Transfer Case Shift Motor Circuit Failure CD4E Code (DTC) P1839 Transmission Transfer Case Shift Motor Open Circuit
What kind of stall test can I do on a CD4E?
The pump, converter apply circuit, converter friction material, internal seals and the TCC solenoid can all be tested while the unit is in the car by performing a Shift Controller Stall Test. This stall test is not a WOT brake stall, where the engine stabilizes at 2500 RPM.
