Just wondering. I bought a parts truck, with a ZF. Truck was high mileage, at least 340K based on the oil change sticker on the door. I got the trans cheap enough that at this point, if it needs a rebuild, the pain in the wallet wont be so bad. I was staring at it, it made me wonder if there were any checks aside from examining the fluid, shifting it thru the gates, and turn the input and output shafts. Is there a secret to inspecting these things without disassembly? What is a normal lifespan of one of these units if they are not abused?
