My friend bought a Toyota 4wd FJ Cruiser standard transmission and wanted to tow it 4 down. Toyota said no. He checked with REMCO and they told him "no go with the standard transmission. Had he bought an Automatic they would put a drive line disconnect on it and it would work". Something about the rear locking axels prevented it. Check with REMCO on your towing needs, they are the 4down towing GURU"S.
