Trenton
Just a Texan transplanted in the Rockies
Hey y'all, I have a 1998 Chevrolet K3500 Silverado CCLB with the 5.7L Vortec and 4L80e trans.
My transmission has no issues and shifts perfectly, but it also has 268k on it and I don't know the maintenance history of it. The fluid is dark red, but doesn't smell burnt. In the almost 4 years and ~28,000 miles I've owned it, I've never changed the fluid.
I've heard horror stories of changing trans fluid and the trans going out at this high of mileage. I just want it to last as long as it can.
I don't tow really heavy right now, maybe 6000 pounds at most. I do go off-roading in the rockies and drive up a lot of mountain grades since I live at 8000 ft elevation. I use Amsoil in the engine, transfer case, both differentials, and I even run their brake fluid, so I'd like to put it in my transmission if it's not a gamble.
So should I change the trans fluid or not?
