1999 GMC B7 Recalls — Canada & USA

The 1999 GMC B7 has two recalls, both involving the automatic transmission: one where a shift cable can pull free of its end fitting and leave the driver unable to select gears, and one where a degraded transmission fluid cooler hose can leak fluid onto the exhaust and start a fire. On the gear selection issue, if the cable separates, the transmission may shift into an unintended gear or direction without warning, raising the risk of a crash. The fluid leak concern is separate in cause but equally serious: as the cooler hose deteriorates from heat over time, it can weep transmission fluid onto the hot exhaust on the passenger side of the vehicle, creating a fire risk.
