Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
Is or has the check engine light or any other warning lights come on on the dash at all with this issue here?
Let me know,thanks Pete
From what you have described here this sounds like a fault with the transmission torque converter staying locked up due to an internal mechanical fault in the torque converter itself or due to the lock-up solenoid failing needing replaced.This will cause the hard shifting as well as vibration and usually with a vibration this can be the torque converter itself or input shaft issue in the transmission, unfortunately.
You will need to have the transmission inspected/tested to locate if the torque converter is the cause or if there is an internal transmission component at fault like the input shaft or any other components in the transmission at fault.In some cases, the transmission has to be removed for inspection.This is usually best checked/tested by a transmission repair facility with the correct test equipment and tools to locate the fault especially if it has to be removed and taken apart for inspection.
