In general a HTOB, if not restrained, will try to rotate as hydraulic pressure is applied. If your hydraulic lines are strong enough they will restrain it. If not ... well you can figure that ending out pretty easily. McLeod offers three general types of HTOBs. One is similar to an OEM style and the other two, while similar, use different techniques to restrain the HTOB from rotating. One uses a sleeve with a tapered entry that uses friction to secure the assembly when it is pushed onto the transmission input shaft. the other uses a more traditional type of rotation restraint. Most HTOB's that that I have seen which live in the bell housing use a mechanical stop to prevent rotation.

By and large I would be reluctant to use hydraulic lines to restrain a HTOB from rotating on the input shaft candle stick. All manufacturers I have seen use some type of mechanical stop other than the hydraulic lines. If your HTOB truly has none it is possible that it / they may have been broken off. If that is true then you might need to obtain some service parts and that brings us back to who manufactured the HTOB if you are going to correct the problem.
