I am sorry your having this problem

is the fluid full ?

when in park will the car NOT roll and lock on the parking lock in the transmission ?

Customer: replied 1 year ago.
the fluid is full and while in park it locks in park doesbit sound like the front pump or tourqe converter
Expert:  Gary replied 1 year ago.

yes it sounds like a pump or converter failure

with the fluid full and it NOT rolling in park this issue is 100 % inside the transmission of the pump or converter

the transmission needs to come out and the converter tested and the pump checked if both test and check out good then the problem is deeper inside the transmission

bot***** *****ne it is 100 % inside the transmission causing this problem
