PROBLEMA Caja RENAULT, RUIDO al ACELERAR. ¿Qué será?¿piñones, engranajes, rodamientos, diferencial?

Problem with the Renault gearbox or front transverse transmission, with a strange intermittent noise in 2nd and 3rd gears. It is unknown if it is the differential, bearings, ball bearings, ball bearings, pinions, gears, or crown drive pinion. In the video, I show the disassembly, visual inspection, and the faulty gearbox. You can see the friction where it scraped, but there is no wear on the gears, bearings, or synchronizers, fortunately. The magnet absorbed all the shavings that were generated.
