This procedure addresses the 1966 Corvette, which does not have a transfer case. The C2 Corvette is a rear-wheel drive sports car with a standard or 4-speed manual transmission, or Powerglide automatic, connected directly to the rear differential.

Warnings

Preparation

1. Verify the actual concern with the vehicle - the 1966 Corvette has no transfer case as it is a two-wheel drive sports car
2. If driveline service is needed, identify whether the issue is with the transmission (manual or Powerglide automatic), driveshaft, universal joints, or rear differential
3. Consult appropriate repair procedures for the actual component requiring service

Procedure

1. 1

   Verify Vehicle Configuration
   Confirm you are working on a 1966 Chevrolet Corvette. This vehicle was produced only as a rear-wheel drive sports car with either a 3-speed or 4-speed manual transmission, or 2-speed Powerglide automatic transmission. No transfer case was ever installed on this model year or body style. The driveline consists of: transmission -> single-piece driveshaft with two universal joints -> rear differential (positraction or open).
2. 2

   Identify the Actual Component Needing Service
   If you were directed to service a transfer case due to driveline noise, vibration, or fluid leak, determine the actual source. Check the transmission tailhousing for leaks, inspect both U-joints for play or binding, examine the driveshaft for balance issues or damage, and inspect the rear differential for leaks or noise. The rear-mounted differential on the C2 Corvette is often misidentified by those unfamiliar with the independent rear suspension design.
3. 3

   Consult Correct Repair Procedure
   Reference the appropriate repair procedure based on your diagnosis: Transmission Service for fluid leaks or shifting issues, Driveshaft Removal for driveshaft or U-joint service, or Rear Differential Service for gear noise or differential leaks. The 1966 Corvette uses a unique independent rear suspension with the differential mounted to the frame, which differs significantly from other Chevrolet vehicles of this era.

Reassembly

1. No reassembly required - this vehicle does not have the component specified

Verification

• Confirm through visual inspection that no transfer case exists on this vehicle
• Verify the actual component requiring service has been correctly identified
• Consult factory service manual or Corvette-specific documentation if uncertainty remains about driveline configuration
