Can the four wheel drive hurt the transmission on your 98 Chevy blazer?
Not usually, the four wheel drive is hooked up after the transmission. If you are having problems with your transfer case it will sound like the transmission because the transfer case is bolted to the back of the transmission. The four wheel drive operates independently from the transmission. If you have a bad transfer case that would cause locking in the drive line it could cause problems, but your vehicle is designed to use the four wheel drive and typical use of your four wheel drive won't cause damage to the transmission. It would be advisable to only use it as necessary because it will decrease your fuel economy by about 20%.
