Some customers may comment that the transmission slips when shifting to second or sixth gear. Customers may also comment that the MIL is illuminated. Upon further investigation, technicians may find DTC P2714 as an active or history code in the TCM.
This condition may be caused by debris such as small metal or plastic chips or small pieces of paper blocking orifices in the spacer plate. This is especially possible if the condition is intermittent as the debris may move and cause the condition by blocking an orifice during one drive cycle and not the next.
Recommendation/Instructions
Remove the valve channel plate and the spacer plate from the transmission.
Inspect the channel plate and the spacer plate for any debris in the areas identified. These are the oil channels and orifices that provide oil to the 2-6 clutch regulator valve. Clean the channel plate and the spacer plate thoroughly. Also clean the valve body thoroughly, making sure that the 2-6 regulator valve moves freely.
