Hi meter01,

Give this a try and see if it works.

GENERIC COMPUTER RELEARN PROCEDURES
Some manufacturers identify a specific relearn procedure which will help establish suitable driveability during relearn stage. These procedures are especially important if vehicle is equipped with and electronically controlled automatic transmission or transaxle. Always complete procedure before returning vehicle to customer. The following general procedures are to be used if driveability problems are encountered after power loss or battery has been disconnected. These procedures may provide an aid in eliminating these problems.

Automatic Transmission

• Set parking brake, start engine in "P" or "N" position. Warm-up vehicle to normal operating temperature or until cooling fan cycles.
• Allow vehicle to idle for one minute in "N" position. Select "D" and allow engine to idle for one minute.
• Accelerate at normal throttle position (20-50%) until vehicle shifts into top gear.
• Cruise at light to medium throttle.
• Decelerate to a stop, allowing vehicle to downshift, and use brakes normally.
• Process may be repeated as necessary.
