jk080 thanks for your help on this. Are the part numbers you gave me okay to use with the earlier 4R70W as it said for 97 & Newer? When you are talking about the upper spring and piston assembly, how is that accessed? Directly Above the lower spring & Piston assembly? Do I Need to unbolt the valve body to access these springs and pistons? Any expert tips when unbolting and removing the valvebody? Thanks For any help anyone can offer!
