A buddy of mine called me for advice : few times ago, some troubles appear:
His truck is a Cheyenne K1500 from 1996 with 6.5.
this started with engine iddling up and down at cold start;
then, ABS light start lighting up (seems it is due to right hub assy)
This past week-end, they change the actuator and put a 1997 actuator with harness "k" to make it fit on his 1996.
Don't know for sure if it is the culprit, but it a fact that now, the tranny stays locked on 1st.
Here are the symptoms:
- the pump light on dash lights up;
- engine runs fine, tach goes up and down then loose, though driving speed stays study;
- gear box stays on 1st, doesn't engage to 2nd and up. Seems sometimes it tries and makes lot vibrations.
I will meet him this evening and see what codes and I can get from ECM.
Any idea?
