I've got a Komatsu D31P-20 and i'm planning to do some transmission maintenance. I'm wondering if this model has a transmission screen or filter that i should be changing. Hoping someone familiar with it can point me in the right direction before i dig in.
 
Absolutely! There's a transmission suction screen and filter in there. You'll want to peek under the seat or check the side panels to get to them. It's a good idea to clean or swap those out during your service
 
Thinking you can skip checking the transmission screen or filter on a Komatsu D31P-20 is risky, ignoring it is how expensive failures happen. If you don't replace or clean it properly, you're basically gambling with your entire drivetrain
