The most likely cause of a transmission housing becoming pressurized in low range only is a damaged O-ring in the range cylinder. This is because the range cylinder is directly involved in selecting the gear range in a transmission. If the O-ring is damaged, it could allow transmission fluid to leak or pressure to build up improperly, but only when the transmission is set to low range, as that's when the range cylinder is actively engaged.
