Transmart is transmissions and transfer cases We sell transmissions parts or rebuild units from Transfer cases We back up all of our work with a 2 year warranty on all transfer case purchased here at South El Monte Transmart. Transmissions are important if not for them we would only have one gear to ride, just like a bicycle without multiple speed gears. Transmissions help us ride from smooth to fast shifting reaching now over 140 mph, that would have never happened if not for the transmission. Here with Transmart we offer a 1 yr warranty on all rebuild transmission units and 90 days on all used transmissions purchased.
