6L80 Transmission Vent Assembly

6L80 Transmission Vent Assembly

Replacement vent assembly for 6L80 and 6L90 transmissions. The vent on sealed transmissions is critical since there is no dipstick to relieve pressure. A blocked vent pushes fluid past every seal in the unit.

Core Transmission Supply carries carefully selected cross-transmission accessories to support installation, maintenance, and upgrades across all popular GM automatic transmissions.
