4L80-Specific Geometry
This crossmember is intended for the 4L80 automatic case and mount position; other transmission versions use different support geometry.
Hawks Mount-System Basis
Engine position follows Hawks motor-mount kit geometry. Builds using another mount system require independent measurement before selection.
Swap Planning
Confirm tunnel and pan clearance, driveshaft length, driveline angle, shifter or linkage position, cooler-line routing when applicable, and exhaust space before final assembly.

Model, trim and equipment availability can vary. Compare the original component, installation location and product photographs before ordering.
- Mock up the Gen V LT engine and 4L80 in the chassis.
- Confirm the engine-mount system and transmission position.
- Support the transmission safely before removing any existing support.
- Test-position the crossmember and inspect tunnel, pan and exhaust clearance.
- Measure driveline angle, driveshaft length and shifter or linkage alignment.
- Complete final tightening and recheck clearances at ride height.
Which automatic transmission is this crossmember designed for?
This version is configured for the 4L80 automatic transmission.
Can another transmission version use the same crossmember?
Do not assume so. Hawks lists separate crossmembers because transmission cases and mount positions differ.
What should be measured during mock-up?
Check the transmission case, tunnel, pan, driveshaft, driveline angle, exhaust and control-system clearances.
How should the part be selected?
Use the exact vehicle equipment and the stated application details rather than body style alone.
Why inspect nearby components at the same time?
Wear or damage around the installation area can prevent the replacement from operating correctly.
