This kit contains all parts necessary to correct shudder for good, in 8L’s units AND can be installed in units that start to exhibit “SHUDDERING” of the TCC system… in most cases, without removing the Transmission Assembly and by installing it from the bottom. We even got the nerve to put the old fluid back in and guess what… NO SHUDDERS!
