2011 GMC Terrain 2.4 with 6T45: which axle-seal part numbers should be checked?
The Terrain-specific job of this page is to show where to stop: a matching vehicle/transmission layer is necessary, but it still does not make one OE automatic for every 2011 Terrain.
What this Terrain page owns
E106 is the only vehicle→transmission premise needed here: 2011 Terrain 2.4L LAF → 6T45, MHC/MH7. The broader bulletin argument across Captiva / Equinox / Terrain already belongs to T-23, so this page starts after that step instead of reproducing it.
The part check has two separate questions
First ask which OE references are in the verified 6T40/6T45 seal record: 24230682 and 24230715, currently bounded to a 2006–2013 catalog interval. Then ask which vehicle side is required: professional catalogs support 24230682 as RH and 24230715 as LH.
Those are not the same evidence claim. E306 keeps at least one marketplace side-label conflict visible, and the full side-source analysis belongs to T-01; this page does not upgrade catalog support into “GM confirms RH/LH.”
Do not use Terrain as an Equinox shortcut
The same GM bulletin also includes an Equinox application, but a shared source does not turn one model page into another model's fitment proof. If the vehicle is a 2011 Equinox 2.4L LAF, use the dedicated Equinox seal page.
This separation matters because the search intent here is Terrain-specific even when part evidence overlaps. Shared evidence is allowed; copied owner logic is not.
Three stop conditions before an order
Stop and verify further if any of these is unresolved:
- Vehicle layer: the vehicle has not been confirmed as the stated 2011 Terrain 2.4L LAF application.
- Transmission layer: 6T45 / the relevant RPO has not been confirmed from vehicle-specific data. Use T-21 for the RPO/VIN workflow.
- Part layer: the required side or the exact OE is still uncertain, or the vehicle falls outside the current seal record's supported scope.
Unverified dimensions, a seller title, or the model badge alone do not close any of those three layers.
Boundaries that still apply to the Terrain answer
This result stays tied to the stated 2011 Terrain 2.4L LAF configuration. A different Terrain year, engine or transmission needs a new vehicle-level check. The RH/LH labels remain professional-catalog support rather than a direct GM public side statement, and no seal dimensions are published here. Shared Equinox evidence is not used as an ordering shortcut, while the conflicting marketplace side label preserved in E306 remains visible.
FAQ
- Which two seal OE references are in the current 6T40/6T45 record?
- 24230682 and 24230715.
- How is the required side established on this Terrain page?
- The working side assignment comes from multiple professional transmission catalogs: 24230682 is supported as RH/right and 24230715 as LH/left. That source level is kept explicit because the current evidence set does not contain a direct GM public side assignment for this pair.
- Does E106 itself prove those two part numbers?
- No. E106 closes the stated Terrain vehicle→6T45 layer. The exact OE layer comes from the separately verified fitment record and catalog evidence.
- Can I apply this page to another Terrain year?
- Not automatically. A different year, engine or transmission configuration needs its own vehicle and part verification. ---
