    Get a scan of the PCM and let us know what codes are read. You will probably see some kind of slip code. It may be that your intermediate clutch pack is failing.

    So the transmission is slipping. Next the technician has to find out why. This can be related to a valve body issue, shift solenoid issue, low transmission fluid, or defective internal clutches.

    A transmission shop should be able, in an hour or two, determine if your problem is in the valve body/electrical, or internal. They can do electrical and external pressure testing.
