i need some help...first when i put my car into gear...no matter what gear it is, could be D to R or R to D..beside neutral..my 93 vigor gives me a strong jerk and sometimes a clunk noise..also when i am driving, i will sometimes hear the same clunk when the trans downshifts..i have an auto trans..mainly on declines but sometimes it doesnt matter..I just want to know what the jerk and this clunking noise could be..any suggestions?? thanks
