Extended Warranty Worth it? For the 2016 Subaru Legacy 2.5L?

I just purchased a used 2016 Subaru Legacy Limited 2.5L with 90k miles. I was offered a 2-year/24-mile extended warranty that covers:

* Engine (internally lubricated parts, block, cylinder heads, water pump, manifolds) * Transmission / CVT (internal parts, valve body, torque converter, case) * All-Wheel Drive & Axles (differentials, CV joints, drive shafts, bearings) * Seals & Gaskets for covered powertrain parts * Normal mechanical wear-and-tear allowance on covered parts

It costs $2k for it, and I'm wondering if I should call the finance manager and cancel it before the bank funds the loan. This would lower my monthly payment by $40. I heard these cars have transmission issues, so I wanted to get opinions on whether I should just keep this warranty or cancel it? It already comes with a 90/3k-mile warranty as a used car purchase.
