One problem related to automatic transmission torque converter has been reported for the 1999 Chevrolet Tahoe. The most recently reported issues are listed below.
The consumer complained about six month ago about problems with the transmission. The dealer replaced the torque converter, six month later, the transmission failed while driving 40 mph. The dealer rebuilt the automatic transmissions at the owner expense. The transmission was completely rebuilt and had been serviced prior to purchase which included a transmission flush. The vehicle leaked fluid, found front pump leaking due to the bearing failure(both were removed and replaced), when the vehicle would get warm, a loud rattling noise would be heard, the a/c would get warm, the fan would stop blowing(fond terminal burnt/wiring repaired), the transmission slipped upon acceleration(found the input carrier bearing coming apart and metal throughout/the transmission was completely reconditioned).
