auto shiofter help super tough to shift

[JORGIE95961]

first time shifting this column in the last 20 years. it was in the cab im using . and since im doing a manual to auto swap im using it. but the damn thing is super hard to shift . Im sure its probably just a lube issue. IVE DISCONECTED IT FROM STEERING COLUMN AND SHIFTED WITH MY HAND SO IT IS DEFINITELY NOT THE LINKAGE . but i have no idea what to take apart to lube any simple fixes to thios before i give up and buy a different column? i shift the trany manual and thats a piece of cake . but the shifter man thats stiff.. any help for a mediocre parts swapper is gladly welcomed and apprecieated!!!!
