ALL CHEVROLET DEALERS
Some early production units may exhibit gear clash when the operator attempts to shift from 2-high to 4-high while the vehicle is moving.
The gear clash condition most often occurs at speeds in excess of 25 MPH. If an owner reports this condition, the following steps should be
taken:
1.
Be sure the owner understands that cold weather may affect the speed at which he can shift without difficulty. Review page 2-18 of
the Owner's Manual with him.
2.
Be sure the owner understands that the shift should be made with a firm "crisp" motion.
3.
Inspect all linkage for proper adjustment. Adjust as required.
4.
If gear clash is still encountered, then it will be necessary to replace the parts listed below.
Follow the procedure for unit repair of the 207 transfer case as described in the 1983 Light Duty Truck Service Manual to install these
parts.
