Diagnostic Aids

When Code EO36 is set, transaxle will be forced into 3rd gear. If code sets due to a grounded circuit No. 1223, 1st and 2nd gear operation will be available only. If circuit No. 1223 is open, 3rd and 4th gear operation will be available only. If fault goes away, normal operation will be resumed for the duration of the key cycle.
