GM add on transmission oil cooler

[Gary Thompson]

Why doesn't GM offer add on transmission oil cooler for 2018 Silverado 1500 WT with 4.3 engine? Dealer said they aren't available for 4.3 engine. They are for the v8's.

Probably because in their eyes the transmission isn't stressed enough behind the 4.3 even while towing.

 

You can do the thermostat replacement from GM or the thermostat mod to lower your transmission temps. GM sells a new revised cooler line thermostat that will lower the temps about 30-40 degrees. The other way is a do it yourself mod that does the same thing for free.

Owners are under the false impression that they want the vehicles to last forever, they are only concerned with the warranty, after that its no longer their problem, its yours.   GM sells new vehicles, they don't want yours to last for ever, they want to sell you a new one.   The bean counters ask the designers if we do this and use this will is last the warranty?  If the engineers answer yes, then the are not going to spend more money to make something better.   Just because is costs a lot of money is no reason to think it should last longer.  A friend has a Range Rover and its a nice vehicle.  But as she says, don't buy one unless you can afford the repairs as they cost a fortune and they are riddled with issues. She barely has 25,000 miles on here 2021 and already they had to replace the brakes 2x and that's not covered under warranty. Not to mention the closest dealer is 400 miles away.
