Code EO36, 4T60E Trans Shift Control Problem: Notes

The 4T60E transaxle is electronically shifted. Within transaxle are 4 solenoids. Solenoid A is used for 1st and 4th gear operation only. Solenoid b is used for 1st and 2nd gear operation. The remaining 2 solenoids are for TCC operation only. All PRNDL indications are ignored as far as transaxle shifting is concerned except manual low. Code EO36 will set if solenoid "B" failed in the off position, which will cause the transaxle to be in 3rd gear and desired gear is 1st, TPS is greater than 5 percent, VSS is greater than 5 MPH and no code EO21, EO22 or EO24 is present. Code will also set if solenoid "B" failed in the on position, which will cause transaxle to be in 1st gear and desired gear is 4th, PRNDL is in 3rd or 4th, TPS is greater than 10 percent and no Code EO31, EO21 or EO22 is present.
