I wanted to find out straight from the source if this product worked for the 5.3 / 10spd trans in the 2020 Silverado Trail Boss.
My initial inquiry to Range Customer Support:
"I see the note it will not work for the 6.2/10spd, but nothing definitive that it will/won’t work on the 5.3/10spd."
Range Customer Support response:
"The RA003 units should work fine for the 5.3L 10 speeds."
This is an electronic device, it either will or it won't. There should be no "should" in their response. Which led to my reply:
"I guess I'm looking for a more concrete answer than "should". Before I spend my money on a part that controls critical engine functions, I'd like to know it will or won't work by design."
Range Customer Support response:
"We have many customers that run the product in there 5.3L 10 speed vehicles and have had great results. The RA003 units do support the 5.3L vehicles with the 10 speed transmissions."
Still no definitive answer.
Being an optimist, I bought their RA003B product from Amazon (they had next day shipping). After using it for less than a week, some days the Auto-Stop Disable feature would work, and some days not. Solid state electronic devices should not do this.
The other issue I have with this Range product is that nowhere on the product's website does it state you need to remove the product when not in use to prevent battery drain. This warning is on the package. Almost like they are worried that might turn folks off from buying their product.
I can't say as I noticed a difference in driving the truck with/without the device installed. Maybe I got a defective one, maybe they don't test much in house and rely on owners to report problems.
Buyer beware is the best advice I can give based on my experience.
