Hi guys I wanted to see if any of you might have an idea what’s going on, I have a 2009 h3t alpha just replaced the trans about a month ago with a remanufactured trans. worked great then I parked it over the weekend, and drove it and it launched in 3rd gear, found fuse 34 was burned replaced it and it worked for about a day then it went out again. Gave me code p0700 and p0976 so I replaced the shift solenoids thinking they may have been bad only for it to continue burning fuses. Any ideas? All I saw in the wiring harness in the pan was some slight discoloration on the wires near the solenoid 1-2 and 3-4 connectors(photo below) everything else seemed fine. Also when I had removed the trans I did a visual inspection of the wires and replaced the plastic protector prior to installing.

You said the trans is only a month old ? What did the company that did the rebuild say?

I’m not sure to be honest with you, they’re a supplier for auto zone (who I got it from) it came with a 3year warranty compared to a 6 week warranty from the local trans shop so it seemed like a good idea at the time. I ordered a replacement harness so we’ll see if it’s that. I’ll also have to check the other solenoids while I have the pan off. Other thing is it seemed to only burn the fuse when the it’s at operating temp so it runs fine when it’s cold, so I don’t know if there’s any other electrical components that affect it
