Vsc, Vsc Off, Chk Engine Lights And Won't Shift Into Od

[boznian2]

As the title says, 3 dash lights and when they are on it won't shift into O/D. We have been through the whole deal with replacing struts and then "VSC" "VSC Off" lights, which was due to incompetent repairs. Wheel speed sensor, hub, tone ring and brake job later that went away almost a year ago. This seems to be something different.

When it first happened the shop told us it had a stored code for engine mis-fire (or knock or ping?) We have had a tune-up and transmission service (and now it runs like a top), but still the same problem intermittently. BTW, it started with just the dash lights and no other symptoms - the not shifting to O/D came on a little later. The vehicle is pushing 200k miles...

Any ideas?

Need to know what the codes are...Knock and missfires will both cause loss of overdrive....

Sorry I didn't respond to this earlier - been hectic.

Anyway, we had both knock sensors replaced and the wiring harness for the knock sensor circuit. So far everything is working...
