I have a 2000 Chevy s10. The service engine soon light comes on maybe 1 or 2 times a month and stays on for 1 to 3 days. With either the light on or off I notice no change in the handling or driving of the truck. It drives just fine. I had Auto Zone pull the codes and they were P0740 P0753 P0758 P0785 and P1860. Could one single thing be causing all of these codes to come up? Please help. Thanks,
Jon

Could be.
You have 5 transmission solenoid/circuit problems.
I would check out transmission wiring inside and out of transmission an all the way to computer for shorts and grounds and connections.
A good repair manual will have repair flow charts for all of the codes.
Let us know how it goes.
