Was it doing the same thing before you installed the engine mounts?

Check your transmission mounts.

You didn’t mention the mileage of your vehicle.

@akarbari
When you say ‘there is no push off’, do you mean the vehicle won’t accelerate?
Just to be clear, is your vehicle equipped with a manual or automatic transmission?

@inthrustwetrust
Yes, vehicle won't accelerate work perfectly when i m using 2nd gear, It's automatic + 1,2,3 gear manual also available,

@akarbari
Does the car shift smoothly & accelerate normally when you drive it in D?
So if I understand you correctly, the vehicle shakes when you shift into R and if you manually shift into 3rd gear, the vehicle won’t accelerate?

Sir, need your experts advise here

@akarbari
Looks like your transmission is on its way out. Take it to a reputed mechanic who specialises in GM vehicles and has a dealer level scan tool.
Also does the rpm needle reflect the jerky shifting? If you can, please make a video & post the link here for others to see.

@inthrustwetrust
Yes sir, I did scanning of my vehicle from GM as well from outside none of them found any code during scanning, Regarding the video so will make it and post soon as requested.
