I have an 02 chevy avelanche: engine codes P0740, P0785, P1860 have come up.

Can anybody tell me if the transmission is going bad or is this electrical problems?

Thanks Lori

 

Lori,
The most likely cause of this condition may be a loss of voltage to the transmission solenoid power supply circuit.
This condition may also be the result of an incorrect installation of an aftermarket electronic device such as a remote starter or alarm system.

 

Thanks it does have a remote starter it has been on for five years do you think it could still be the problem

 

My 2000 Chevy Lumina has been diagnosed with a clutch circuit malfunction. Is this an expensive repair? I am having them replace the filter and flush the transmission because it's very dirty and rusty

 

I bought a have a 2000 Chevy Lumina with 147,000 having the transmission flushed but was diagnozed with a clutch circuit malfunction, is this a costly repair.

 

jrobil, you may want to start a new thread with your question. "hijacking" an old thread, or someone else's, is generally not wise. post your question in your model's category, or maybe in general tech.
