Which filter plate is Gen 1: 24242274 or 24263196?

In the captured 2012 Chevrolet Sonic dealer/genuine-parts catalogue, 24242274 is labelled Gen 1. GM’s public 24242274 page independently confirms the part identity and OE classification, but not the transmission-RPO fitment.

Which filter plate is Gen 2?

In the captured catalogue evidence, 24263196 is labelled Gen 2. Separate captured catalogue contexts place it in LUV/MH8 and MH9/6T30 applications. These are specific catalogue examples, not universal fitment.

Is 24242274 only a 6T30 part?

No such rule is supported. The captured 2012 Sonic catalogue shows 24242274 in both LUW/MH9 and LUV/MH8 contexts, so the transmission name alone is not a sufficient selection key.

Does 24263196 fit every Gen 2 6T30 or 6T40?

No. The evidence establishes specific catalogued contexts only. It does not establish universal same-generation interchangeability or fitment for every 6T30 or 6T40.

Can I use model year alone to identify Gen 1 vs Gen 2?

No. GM PI0604C records Gen 1 exceptions during the 2012 transition. Verify the actual Gen 1 / Gen 2 or 2nd-design application boundary rather than using model year alone.

Is this the same comparison as 24237508 vs 24268086?

No. 24237508 and 24268086 are transmission fluid filters. This article is about control-solenoid filter plates, a different part class with a different evidence boundary.

24242274 vs 24263196: which control-solenoid filter plate is Gen 1 and which is Gen 2?

Short answer: in the dealer/genuine-parts catalogue evidence we captured, 24242274 is labelled Gen 1 and 24263196 is labelled Gen 2. But that does not create a simple “6T30 part versus 6T40 part” split. The captured evidence shows the generation concept crossing MH9/6T30 and MH8/6T40 contexts, so the transmission name alone is not a sufficient selection key for these filter plates.

This article owns the part-number/generation comparison. For the general method of identifying GM 6T Gen 1 vs Gen 2, see our Gen 1 vs Gen 2 identification guide. For the separate 6T30 fluid-filter comparison 24237508 vs 24268086, see the fluid-filter article.

What does GM officially confirm about 24242274?

GM’s public Chevrolet Parts page identifies 24242274 as an Automatic Transmission Control Valve Solenoid Filter Plate and shows Classification OE.

That closes the identity/function question for 24242274. It does not close the transmission or generation-fitment question, because the public vehicle table does not provide the transmission RPO needed to map those vehicle rows to 6T30, 6T40 or 6T45.

What does the captured 2012 Sonic catalogue show?

In a captured 2012 Chevrolet Sonic dealer/genuine-parts catalogue, the two identifiers are distinguished by generation:

24242274 — labelled Gen 1.
24263196 — labelled Gen 2.

The same captured page shows 24242274 in both LUW/MH9 and LUV/MH8 contexts. Existing GM service evidence identifies the relevant 2012 Sonic LUW/MH9 application as 6T30 and the LUV/MH8 application as 6T40.

For 24263196, the displayed 2012 Sonic catalogue context is LUV/MH8, a 6T40-side example.

Source label: these generation assignments are catalogue-mirror evidence. They are not presented as a direct GM public target-part page for 24263196.

Where does 24263196 appear with 6T30 / MH9?

A separate persistently captured GM EPC catalogue mirror for a 2015 Chevrolet Cruze places 24263196 under the nearest preceding section Automatic transmission (mh9)(6t30) case & related parts. The part row describes 24263196 as Plate, cont sol vlv fltr (gen 2) and includes the restriction PJ, PL(LUW, LWE, MH9).

That is a specific catalogued MH9/6T30 context for 24263196. It is not proof that 24263196 fits every 6T30, every Cruze, every Sonic, or every Gen 2 transmission.

The full reasoning and the correction of our earlier 6T30 rejection are documented in the T-22 reverification article.

Why generation matters more than the transmission name here

GM PI0604C documents substantive Gen 2 changes in the valve-body/control area, including a revised filter plate. The same bulletin also explains that Gen 2 is the diagnostics/repair term while 2nd design is used in the parts-catalog context.

Now combine that service information with the catalogue observations:

24242274 is catalogued as Gen 1 and appears in both MH9 and MH8 contexts.
24263196 is catalogued as Gen 2 and appears in captured MH8 and MH9/6T30 contexts.

The bounded conclusion is that the transmission code alone does not separate these two filter-plate identifiers. Generation/design is a required selection boundary in the evidence we captured.

This does not mean transmission/application details stop mattering, and it does not mean all filter plates within the same generation are interchangeable.

Why 2012 is not a clean cutover year

GM PI0604C records Gen 1 exceptions during 2012 and describes covered 2013 vehicles as Gen 2. So a rule such as “2012 = Gen 1” or “2012 = Gen 2” is too crude.

For an actual inquiry, use the exact vehicle/application plus VIN, production configuration or application-specific catalogue/service information to establish the Gen 1 / Gen 2 or 2nd-design boundary.

How should 24242274 vs 24263196 be selected?

Confirm the exact vehicle/application. Do not start from the words 6T30 or 6T40 alone.
Establish the generation/design boundary. Gen 1 vs Gen 2 / 2nd design is technically meaningful for this valve-body/filter-plate area.
Check the part number against application-specific evidence. A catalogue instance is evidence for that instance, not a universal interchange rule.
Do not use model year alone. 2012 is a documented transition year.

This is not the 24237508 vs 24268086 filter comparison

Do not mix the two part classes. 24237508 and 24268086 are transmission fluid filters. 24242274 and 24263196 are control-solenoid filter plates. Similar “Gen 1 / Gen 2” wording does not make the parts or their selection logic interchangeable.

For fluid-filter selection, use 24237508 vs 24268086. For the wider 6T family relationship, use the 6T30/6T40/6T45 family guide.

What about 24299031?

GM’s current public page identifies 24299031 as a Control Solenoid Valve Filter Plate with OE classification. Dealer/genuine-parts catalogue records report 24263196 as replaced by 24299031.

OEProof does not label that relationship as GM-confirmed supersession because we have not captured a GM-primary predecessor statement directly establishing 24263196 → 24299031.

FAQ

Which filter plate is Gen 1: 24242274 or 24263196?: In the captured 2012 Chevrolet Sonic dealer/genuine-parts catalogue, 24242274 is labelled Gen 1. GM’s public 24242274 page independently confirms the part identity and OE classification, but not the transmission-RPO fitment.
Which filter plate is Gen 2?: In the captured catalogue evidence, 24263196 is labelled Gen 2. Separate captured catalogue contexts place it in LUV/MH8 and MH9/6T30 applications. These are specific catalogue examples, not universal fitment.
Is 24242274 only a 6T30 part?: No such rule is supported. The captured 2012 Sonic catalogue shows 24242274 in both LUW/MH9 and LUV/MH8 contexts, so the transmission name alone is not a sufficient selection key.
Does 24263196 fit every Gen 2 6T30 or 6T40?: No. The evidence establishes specific catalogued contexts only. It does not establish universal same-generation interchangeability or fitment for every 6T30 or 6T40.
Can I use model year alone to identify Gen 1 vs Gen 2?: No. GM PI0604C records Gen 1 exceptions during the 2012 transition. Verify the actual Gen 1 / Gen 2 or 2nd-design application boundary rather than using model year alone.
Is this the same comparison as 24237508 vs 24268086?: No. 24237508 and 24268086 are transmission fluid filters. This article is about control-solenoid filter plates, a different part class with a different evidence boundary.
