Scotty,
I purchased a 2013 Chevy Express 3500 cutaway, 71K miles on it, and I’ve had the tranny fluid changed twice and has a Minnie Winnie attached to the back half.
Coming back from a trip to Northern California I was about 20 miles from home and I noticed the transmission started shifting up a gear and down a gear. When I stopped at a red light and it turned green it wouldn’t move an inch! I sat there for about 20 minutes before someone stopped and pulled me off the road. While sitting there the transmission light came on said it was overheating, so I shut it off.
I sat there for 3 weeks (good thing I had lots of water and food). I called 3 different mobile mechanic’s and none of them came out. I called 3 repair shops and they told me that I needed a new transmission! I said how can you tell me that without looking at it. They just know…$4,900 to fix it. I mean come on at least make an attempt to analyze it before you try and steal my money.
Any, I sat there for another week before a couple of buddies and I towed back to my house. Of course we waited until about midnight before we started. Got back with no tickets or accidents.
So, now it starts but immediately tries to shift in gear without me even shifting, it’s in park! Even if I try to start it in neutral it’s starting like it’s already in gear but it won’t move. Now this is a 6 speed automatic/manual transmission and have never had issues with it! I always bragged about how good the transmission was and this happened with no warning.
I’m puzzled! The Blue Driver scan shows a few codes, one was bad ignition switch, I replaced that, it said ECM/PCM had a bad ground wire pulled the wires connector’s and cleaned them along with the BCM.
It feels like the brakes engage as soon as I start the engine.
I’m pulling my hair out trying fix this problem! Any ideas would be greatly appreciated!
Thanks, love your videos!
Wow! I'd really sounds like the transmission is just gone toast. Realize those aren't the greatest transmissions and you were towing stuff. They're bad enough. Just pulling themselves when you toast stuff. It'll often strain it unlike you say it feels like the brakes come on when you put the car in gear. I mean really. You could jack it up and if you see the wheels aren't locking up, you know it's the transmission locking up internally and not letting it move
I didn’t have the OBD codes when I asked my question but, here they are:
P1682
B1380
B1395
B1529
B3600
Also, I wasn’t really towing anything. The Minnie Winnie is attached to the back half of the cutaway.
Thanks for the update.
good thing I had lots of water and food
Your vehicle stalled 30 minutes from home, so you decided to hang out on the side of the road for a whole month?
{black}:surprised:
The Blue Driver scan shows a few codes
I could be wrong, but I don't think BD will show transmission faults.
Tow the van to a transmission specialist for further analysis.
The transmission on my 2013 Express died too (55,000 mi). Turned out to be the control module. I had that replaced and reprogrammed by an automotive electrical shop. As luck would have it, the TCM roasted the rest of the transmission too. A year later, it had to be replaced as well. $5k sounds about right.
