Which OE candidate is verified for the “6T45 pump seal” intent?

24230700 is the primary verified OE candidate within the current evidence set. A real order still requires confirmation of the specific 6T45/RPO application.

Why is searching only by “6T45” not enough?

Because part fitment depends on the specific vehicle configuration, year and revision. Confirm the vehicle's transmission first, then the exact component.

What if the search started because ATF is leaking?

Localize the leak first. PI0950 does not identify 24230700 from a symptom alone; axle/output and front-area sealing points must be separated.

Can 24230700 be added to 6T30 because 6T30 also appears in PI0950?

No. PI0950 is service-condition evidence, while the current part-fitment record for 24230700 excludes 6T30.

6T45 pump seal: is OE 24230700 verified?

Short answer: 24230700 is the primary verified OE candidate for the 6T45 pump-seal intent within the current evidence set and still requires vehicle-specific follow-up verification. A public GM source identifies 24230700 as an Automatic Transmission Fluid Pump Seal with Classification OE, while OEProof's current fitment record includes 6T45 within a bounded 2006–2013 catalog scope. That is not a universal rule for every 6T45.

What 24230700 allows us to say

E201 supports the part number, function and OE classification. The 6T45 application layer comes from the separate verified fitment record rather than from the authority of the GM identity page; the method for separating those layers already belongs to T-26, so it is not repeated here.

In other words, 24230700 answers “what verified candidate do we have for this pump-seal intent?” It does not yet answer “does it fit this exact vehicle?”

The main gate on this page is proving that the vehicle actually has 6T45

Before choosing an OE, confirm the transmission on the actual vehicle. Use RPO/VIN or another documented configuration source; the general process belongs to T-21. If the question concerns the 2011 Captiva / Equinox / Terrain 2.4L group, its vehicle-to-transmission argument already belongs to T-23 and is not duplicated here.

Only then should the exact year/revision be compared with the current 24230700 scope. A seller title containing “6T45” is not enough on its own.

Why there is a separate 6T40 page

The current fitment record contains the same OE in both 6T40 and 6T45 contexts, but the user intents are different. If the vehicle is confirmed as 6T40, use C4. This C5 page does not try to answer for the whole family and does not reproduce the 6T40 argument.

If the search started from a leak, diagnose the location first

PI0950 (E401) shows that GM documented a scoped torque-converter-housing / converter-seal leak condition on certain 6T30/6T40/6T45/6T50 applications before the bulletin's February 1, 2013 build-date boundary. The bulletin does not say “front ATF leak = buy 24230700.”

First localize the source: axle/output seals and the pump/front-area seal are different positions. Use T-06 for that diagnostic split. Only after localization should the exact OE question resume.

6T45-specific verification checklist

Question	What must be closed before an order
Which transmission is on the vehicle?	6T45 is confirmed by a vehicle-specific source
Which component is required?	the pump-seal function, not an axle/output seal
Is there part-level support?	24230700 is checked within the current 6T45 fitment record
Is the year/revision inside scope?	current catalog scope is 2006–2013; outside it needs a new check
Can one leak symptom select the part?	no; localize the leak first
Can 6T30 be added “by family”?	no; the current record excludes it

If any of these items is unresolved, the technical answer should end with additional VIN/RPO/application verification rather than a purchase assumption.

Why 6T30 stays outside the boundary

The fact that 6T30 appears in the broader PI0950 service bulletin does not make 24230700 a 6T30 part. The current fitment record for this OE is bounded to 6T40/6T45 and explicitly excludes 6T30; service-condition evidence and part fitment are different evidence types.

It does not publish seal dimensions.
It does not claim PI0950 establishes failure prevalence.
It does not turn February 1, 2013 into a universal fitment cutoff.
It does not select a part from a leak symptom alone.
