$36 (P1790) - Fault Immediately After Shift

Name of code: $36 (P1 790) - Fault Immediately After Shift

When monitored: After a speed ratio error is stored.

Set condition: This code is set if the associated speed ratio code is stored within 1.3 seconds after a shift.

Theory of operation: This code will only be stored along with a 50 series code. If this code is set, it indicates the problem is mechanical in nature. When this code exists, diagnosing the transmission should be based on the associated speed ratio code and only mechanical causes should be considered.

Transmission Effects: None

Possible causes:
- Mechanical causes as listed under associated speed ratio code.
