Which pump-seal number is verified for 6T40?

24230700 is the primary verified OE candidate within the current evidence scope; a real order still requires confirmation of the specific 6T40/RPO application.

Does 24230700 apply to 6T30?

The current verified fitment record explicitly excludes 6T30. That limit comes from the OEProof fitment record, not from a separate statement on GM's public identity page.

If a 6T40 leaks from the front area, does that mean 24230700 is required?

No. PI0950 does not identify an exact OE from a symptom alone. Localize the leak and confirm the transmission/application first.

Can the same OE be used in a 6T45 context?

The current fitment record also supports 24230700 for 6T45 within its bounded scope; the separate C5 page owns that query.

6T40 pump seal: which OE number is verified for 24230700?

Short answer: GM's public record identifies 24230700 as an Automatic Transmission Fluid Pump Seal with Classification OE. OEProof's verified fitment table keeps the same OE as CONFIRMED for 6T40 / 6T45 within a bounded 2006–2013 catalog interval. For the 6T40 pump-seal intent, 24230700 is the primary verified OE candidate for vehicle-specific follow-up verification. The current fitment record explicitly excludes 6T30.

What GM directly confirms about 24230700

Field	Supported conclusion
GM Part #	24230700
Name	Automatic Transmission Fluid Pump Seal
Classification	OE
Source	E201 · public GM Parts Store record

E201 establishes part identity and function; what OEProof means by CONFIRMED and how identity is separated from fitment are already owned by T-26 using 24230700 as the worked example, so that method is not re-explained here.

Why 24230700 is relevant to the 6T40 query

gm_6t_fitment_v3.csv keeps 24230700 as CONFIRMED for 6T40 / 6T45, with a pump/stator-area function and a current 2006–2013 catalog interval. Once a specific 6T40 application is confirmed, the number can therefore be used as a verified OE candidate, not as a universal part for every vehicle carrying a 6T40 label.

Why 6T30 is excluded here

The current verified fitment record explicitly excludes 6T30. That is a conclusion from OEProof's verified fitment table, not a field on GM's public identity page; E201 itself does not say “not for 6T30.”

What PI0950 contributes — and what it does not

E401 is based on GM PI0950, which documents a torque-converter-housing / converter-seal ATF leak condition on specified 6T30/6T40/6T45/6T50 applications before the bulletin's February 1, 2013 build-date boundary.

For this page, PI0950 is only scoped service-condition evidence. It does not prove family-wide leak prevalence, identify 24230700 from any front-area leak, turn the bulletin date into a universal fitment boundary, or make 24230700 the only repair solution.

How to verify a 6T40 application before an order

Confirm the vehicle actually carries 6T40; the RPO/VIN workflow is in T-21.
Confirm that the required component is the pump-seal function, not an axle/output seal or another sealing point.
Keep the current 2006–2013 catalog interval visible without turning it into a universal model-year rule.
Do not transfer 24230700 to 6T30.
If the starting complaint is an ATF leak, localize it first; the external axle/output versus front-area distinction is covered in T-06.
The final order decision should follow the vehicle-specific VIN/RPO/application check rather than the generic query alone.

Why this page does not own the 6T45 query

This page answers the 6T40 pump-seal intent. The separate C5 / 6T45 pump-seal page uses the same OE within its own owner intent rather than turning one page into a universal family answer.

What this article does not claim

It does not apply 24230700 to 6T30.
It does not claim the GM identity page itself proves every 6T40/6T45 application.
It does not publish seal dimensions.
It does not claim family-wide leak prevalence from PI0950.
It does not turn February 1, 2013 into a universal fitment date.
It does not diagnose a part number from one leak symptom.
It does not imply a commercial affiliation between OEProof and GM from Classification OE.
