Just need to know if we can pull the transfer case without removing the transmission on a 1990 Chevrolet C1500, 5.7L, 4x4.

Good evening,

Yes, you can.

You will need to remove the cross member, both driveshafts and the linkage

You will need to support the transmission with the cross member removed.

NOTICE: When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct part number fastener is not available, a fastener of equal size and strength (or stronger may be used. Fasteners that are not reused, and those requiring thread locking compound will be called out. The correct torque value must be used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.

Remove or Disconnect
1. Negative battery cable.

Raise the vehicle. Support with safety stands.

2. Skid plate (if equipped).

Drain the oil from the transfer case.

3. Front propeller shaft.

4. Left strut rod.

5. Rear propeller shaft.

6. Electrical connections at the transfer case.

7. Transfer case shift linkage at the transfer case.

Support the transfer case with a jack.

8. Bolts (122) and spring washers (123) (if used).

9. Gasket (121).

Hi! From the procedures, it looks like you don't have to pull the transmission to pull the transfer case. For your convenience, I have attached the removal and replacement procedures.
Best of luck!
