Transmission Fluid Change

[Orlando_Castaway]

Have a 2019 Silverado 1500 LT 2WD with 30K -- towing a boat for last 10K miles.

What else on the 2019+ needs to be done along with the transmission fluid change on the 2WD?

Since you are already going to do the transmission, it's hardly any more money to do the rear diff fluid. If you are doing the work yourself, it's maybe $20 in fluid to do the rear diff.

 

Past that, you have no other fluids to change. You don't have a transfer case and no front diff.

If you drop the pan on the 10 speed you will want to change the transmission filter as well

 

if not you would just be a doing a flush and fill and not removing the pan

Rear differential as already stated. Then you will be good to go.
