Symptom/Condition:
Some vehicles may exhibit one or more of the following performance conditons:
1. Perceived lack of power in third gear due to converter Lock-up iIn 3rd gear. This reprogramming eliminates 3rd gear look up.
2. Surge after lock-up (40-45 m.p.h.) in 4th gear. This reprogramming raises torque converter lock-up speed to 52 m.p.h.
3. Transmission does not upshift from 3rd gear after a 4/3 downshift. (Most often noticed when cruise control is engaged.)
