4L60E går framover i samtlige gir?

[Biringen]

The 4L60-E family of transmissions use 2 shift solenoids, initially called Shift Solenoid A & Shift Solenoid B, later changed to comply with OBD II (On Board Diagnostics revision 2) regulations to 1-2 Shift Solenoid & 2-3 Shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, 4 distinct gear ratios can be achieved. The shift solenoid pattern, also sometimes referred to as solenoid firing order, is as follows;

<b>Shift Solenoid Pattern</b>

 

1-2 Solenoid 2-3 Solenoid

 

1st Gear On On

2nd Gear Off On

3rd Gear Off Off

4th Gear On Off

 

EDIT

Så kan hende begge solenoidene er kaputte
