I have an 87 XT turbo with the computer controlled 4 speed auto tranny. I was wondering if there is a direct bolt in lock up torque converter for better efficiency? As far as i know the torque converters they came with were not lock up and thus not as efficient at higher speeds. If anyone know of one that is a direct bolt in, i'd appreciate it. I also plan to install a magasquirt 2 ECU later, so keep in mind it will have to be compatible with that. Thanks in advance.
