Highlights:
Genuine OEM GM 24256129 internal TEHCM / control-solenoid assembly (w/ body & TCM) for Gen 1 6T70 / 6T75 transmissions. Bosch-marked housing. This is the full internal assembly — not a bare harness. TESTED / KNOWN GOOD at sourcing (not reman, not new).
Fluid residue: May have some light ATF / transmission fluid residue on the housing and passages — expected on pre-owned parts. Wipe/clean as needed at install.
Verified fitment: 2011 Cadillac SRX and 2011 Buick Enclave with 6T70 / 6T75 Gen 1 TEHCM.
Additional year/make/model applications are not OEM-EPC verified here — confirm by matching the part number on your removed unit and/or VIN/EPC. Gen 1 and Gen 2 are NOT interchangeable. Not for 6T40 / 6T45 or 6L80 / 6L90.
What\'s included: 1× OEM GM 24256129 TEHCM / control-solenoid assembly (w/ body & TCM), as shown. Connector appears ~16-pin (two rows of 8) from photos — photo-counted, not EPC-confirmed.
IMPORTANT — Programming & install: Typically requires programming / VIN adaptation (SPS / J2534 or equivalent). This is NOT plug & play and NOT “no programming required.” Buyer is responsible for correct generation (Gen 1 vs Gen 2), part-number match, installation, and programming. Testing confirms the unit functioned as tested — it does not replace correct vehicle match or programming.
Not included: Programming, labor, fluids, gaskets/seals (unless shown), or other transmission hardware.
Returns / buyer notes: Returns for wrong generation, wrong PN, or programming issues are buyer responsibility when the part matches this listing. Check all photos for tab/pin condition before purchase.
Questions before you buy? Message with your VIN and the PN on your old unit — happy to help confirm fitment.
