I have had three suburban, 1987, 1996 and 2016 all three have had transmission problems with less than 100,000 miles. The 1987 and 1996 had full transmission rebuilds under extended warranties. After rebuilds they lasted into the 200,000 to 221,000 miles before trading off. The 2016 they would only cover the replacement of the torque converter. Waiting to see how long it goes before it develops transmission problems. Chevy has always had weak transmissions and the after market rebuilds have always been better.
