My 2018 Silverado 5.3/6L80E had to have transmission replaced. Shop stole the cooling fans. Is there a set that will work better than OEM ?

[Roadblock_70]

My truck is a 2018 Silverado 1500 LT Z71. It had two electric cooling fans on it. I took it to a shop that was supposed to be competent at rebuilding 6L80Es. A month before I had installed a new water pump, new 160degree thermostat, and coolant temp sensor.

 

 

The transmission went out at 135,436mi.

 

I was told the transmission was done. I got there and the guy running the shop tried to treat me like an 18yo sorority girl. He claimed he had installed a new radiator, and tried to take credit for installing my water pump, thermostat, and cooling sensor. I called a rollback then, and while I was looking at it, I noticed the twin factory cooling fans were gone and the shop had installed a single fan and it was held in with wire tie.

 

I can remember when I replaced my water pump, there were two electric fans behind the radiator. there is now only one and it is hanging there by a wire tie

 

I got the truck out of there and hauled home ASAP.

 

Is there a set of aftermarket fans that would work as well if not better than the fans that were stolen off of the truck ? Like I could order from Summit ? Or do I need to find a set of factory fans at a dealer someplace ?

 

In addition, I did not request that this shop would delete DOD, but I have found out that they did turn off the DOD/AFM and in addition the speedometer is not reading properly because they screwed with the tire size- the tires on it have always been stock.

 

Is there a chance that this shop could have done something in the ECM/PCM/BCM to screw with the engine coolant system ?

 

Thanks, this has been a nightmare of two weeks which just got worse today when they tried to screw me on the bullshit of the waterpump, thermostat, and I've since found out that they disabled the DOD when I did not ask them to.

 

Pre-2008 I used to use a tech2. What is the comparable tool and software that I can buy to find out all this shop did, and determine what they screwed up ? I know it will cost $2000-$4000 but I will get a lot of use out of it given that I have several GM vehicles.
