Wa Alaikum Assalam.
As brother Abbas mentioned, this most likely seems like use of wrong fluid. For CVT gearbox, ATF should not be used as both fluids have different lubrication properties and friction additives.
Another problem with Honda CVT is that only Honda CVTF is to be used. Any other CVT fluid shall not work or would reduce the usable life of the transmission.
The problem has to be addressed based number of things:
1-Please confirm which oil was used
2-How much kilometers is the car driven since then?
3-How was the CVT fluid level checked? Was it check on a cold engine or hot engine? Low or high fluid level is a disaster.
4-Was there any battery disconnection during this process?
5-Describe the vibration under different scenarios in detail. Steady input on accelerator at a low speed cdrive, does that cause vibration? What is off-idle response? Jerky or smooth or just lacking power?
6-Observe any burning smell on the fluid?
7-what the current mileage of the vehicle. is there any CNG history?
8-When was the CVT fluid changed last time before this, how have you been maintaining your vehicle
All these factors are important to diagnose. It may well be a situation that you may still have to replace your transmission after doing another Honda CVTF flush. And by flush, I mean flush disconnecting the cooler return line, not just drain and refill. CVTF is expensive. About 6k if original from 3S. More if flush to be performed. So bear this cost in mind that it may be a total loss after the flush.
