Part Description
This transfer case was removed from a 1998 GM Trucks CT1500 and has been professionally inspected for quality and functionality. The unit is in excellent condition and is currently on our shelf, ready for immediate shipment. This OEM transfer case features electric shift operation controlled by a dash switch and is designed to work with the 4L60E automatic transmission in 4WD applications.
Transfer cases are critical components in 4WD vehicles that distribute power between the front and rear axles. Common reasons for replacement include internal gear wear, chain stretch, bearing failure, or case cracking due to age and high mileage use. When your transfer case fails, you may experience grinding noises, difficulty shifting between 2WD and 4WD modes, or complete loss of 4WD functionality.

Frequently Asked Questions
Will this transfer case fit my 1998 Chevy K1500?
Yes, this transfer case is compatible with 1995-1999 Chevrolet and GMC 1500 series trucks equipped with 4WD and the 4L60E automatic transmission. Please verify your vehicle has electric shift operation rather than manual shift.
What transmission does this transfer case work with?
This transfer case is specifically designed to work with the 4L60E automatic transmission. It will not fit vehicles equipped with manual transmissions or other automatic transmission types.
How do I know if my transfer case needs replacement?
Common symptoms include grinding or whining noises when engaging 4WD, inability to shift between 2WD and 4WD modes, or fluid leaks underneath the vehicle. If your 4WD system is not engaging properly, the transfer case may need replacement.
Is this an electric shift or manual shift transfer case?
This is an electric shift transfer case controlled by a dash-mounted switch. It is not compatible with vehicles that have a manual floor-mounted shifter for the transfer case.
What is included with this transfer case?
This listing includes the complete transfer case assembly. The electric shift motor and internal components are included, but you may need to transfer your existing driveshafts and mounting hardware during installation.
Can I install this transfer case myself?
Transfer case installation requires lifting the vehicle, supporting the transmission, and proper torque specifications for mounting bolts. We recommend professional installation due to the weight of the component and the precision required for proper driveline alignment.
