Hi,
This sounds like the shift lever is out of adjustment causing the manual valve inside the transmission to partially engage each gear. Basically, the shifter says it is in D or R etc but the transmission is not actually in that gear because the linkage is out of adjustment.
I attached the procedure for both a column shift and a floor shift so please use the one that your vehicle has.
If this is not the cause then you definitely have an issue inside the unit and it will need to be torn apart to determine the root cause.
Let me know if you have questions about this. Thanks
