Diagnostic Aids

When Code 36 is set, transaxle will be forced into 3rd gear. If code sets due to a grounded circuit No. 1223, only 1st and 2nd gear operation will be available. If circuit No. 1223 is open, only 3rd and 4th gear operation will be available. If fault goes away, normal operation will be resumed for duration of key cycle.
