    . Check the turbo--it may be developing problems. If you don't use full synthetic heavy duty diesel oil, it's only a matter of time until the turbo fails. Torque requirements are greatest in 1st gear.

    . Check/replace the Variable Speed Sensor (VSS).

    . Drop and clean the transmission pan and magnet, change the filter, and refill with synthetic ATF. With PCMs, engine and transmission problems are often inter-related.
