Can a clogged filter cause transmission to slip?

2000 Silverado, Ext. cab, 4.8L engine, 2wd, 272,000 miles. Fluid level is fine. Transmission has never been serviced.

Transmission has started slipping. I am figuring that it has seen it's better days and will have to be replaced or rebuilt. I am getting estimates now.

My question is this, could the filter be clogged and causing this? Wondering if I shouldn't try replacing the filter before paying a bunch of money for repairs. Thanks

generally no when a transmission starts slipping its generally going to take more than a filter change to solve the issue and you are looking at a rebuild or replace but if you want to spend a few bucks trying a new filter and fluid most do, but I just would not expect it to work for you but since it is a last ditch effort would probably dump a can of b12 chemtool in it and drive it through the gears to attempt to clean off the clutches and plates then change the fluid and filter.

If that transmission is anything like 5.3L engine one, you are, maybe, looking at few bucks to BUY the filter kit but at the hell of work to replace the filter. As you'll have to remove exhaust, bent shifter cable bracket, have yourself all covered in ATF and, in addition, being Swiss watch precise with reinstalling the pan, as if you touch solenoids plugs and knock them off.....
When you will be rebuilding trannie, or replacing it, replace torque converter same time. REPLACE it. Or, you will have to replace it short time after. That's how automotive gremlins work.
And, the rear main seal. Or, it will start leaking. As I said. You THERE. do it all.
