Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

In some cases this is due to debris build up in the transmission valve body and in some cases a simple transmission flush/filter change can free up and remove the debris to correct this here.I have also seen the valve body itself fail or act up like this as well needing replaced.These are usually the two most common causes for this fault here.If you have not flushed the transmission to try and free up and remove debris this needs done.If this was already done this may be the valve at fault needing replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

Here is the removal procedure for this valve body.You want to make sure the bolts go back into their correct locations and torqued properly.

1. Remove air cleaner and duct assembly.

2. Disconnect negative battery cable from battery.
3. Disconnect positive battery cable from battery.
4. Remove hold-down retaining nut and screws, and lift off battery hold-down retainer.
5. Lift the battery out of vehicle, and place in a safe location.

6. Disconnect PCM J2 (black 28-way) harness connector by moving locking device toward fender.

NOTICE: ABS equipped vehicles require the master cylinder to be moved off booster studs and the ABS mid-rail bracket bolt removed to allow the system to be lifted slightly for removal of the valve body cover. Use care not to bend or kink brake lines. After removing the valve body cover place the master cylinder back on the booster studs.

11. ABS equipped vehicles, remove master cylinder-to-booster nuts and ABS mid-rail bracket bolt.
