TOYOTA / AISIN CVTs 300/100 series using the K311/XB-20LN CVT as an example Mileage 130,000 km There's a myth about CVT diagnostics, especially among those who specialize in auto parts: it's quite difficult to diagnose a CVT without disassembling it. Yes, you can check the pressure, temperature, and lockup, but that's usually where the diagnostics end. Buying a CVT is a gamble, a "pig in a poke." Yes, it's a gamble, but the risks can still be minimized. You need to squeeze everything possible out of diagnostics, both computer diagnostics and non-destructive inspection. This also applies to buying a used CVT. I won't delve into issues with bearings, solenoids, etc. During a visual inspection, you need to assess four points: 1) Is the sealant original (factory or aftermarket) 2) How dirty is the interior and any odor 3) Wear and damage to the primary and secondary pulley cones 4) Belt protector wear. If you remove the valve body, you can assess the belt stretch. Side N2 has holes for the speed sensor, oil pressure sensor, and dipstick. Yes, there should be a dipstick, but it's plugged. The only hole that allows you to quickly inspect the inside of the CVT without removing the oil pan is the oil filler hole. It's on Slide N3 and easy to access: remove the left front wheel and the plastic cover. Slide N4: If you've removed the oil pan (about 4.3 liters will drain, 8.6 liters total), you can remove the filter and fully assess the cones and belt (protector). After removing the valve body, you can assess the belt stretch by checking the gap (stretch it with a screwdriver, etc.) between the sections. In the video: Using the filler hole, assessing the wear of the primary pulley cones. The sealant (pink = factory) is also visible. The CVT is without repair. Primary pulley cones, valve body side entry Secondary pulley cones, which can only be inspected in detail with the oil pan removed, as they are located above the primary pulley. Belt tread wear is an important indicator of the approximate mileage and driving style. The tread is present and undamaged; this is normal for 130,000-150,000 km. #proverka_avtomobilya_samara
