My Honda Civic 2016 gearbox feels like it’s slipping a little when driving off from a stop after a hard braking which activates ABS, if the abs doesn’t activate it doesn’t slip even if the braking is quite hard. CVT fluid replaced every 25k miles. Gearbox feels fine otherwise while accelerating and braking.
If it was slipping it would set a code for that, you’d have a bunch of lights on the dash.
