Know This Transmission Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this transmission family:
A quick look at your own vehicle makes sure the right transmission shows up:
- Verify the 8th digit of your VIN is D (indicates 3.6L V6 engine).
- Verify your Service Parts Identification sticker has RPO code M7V or MY9 (FWD 6T75). If you see M7X, your vehicle is AWD.
- Look under the vehicle to confirm it is Front-Wheel Drive (no transfer case or rear driveshaft).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support fixture
- Subframe/transmission jack
- J2534 pass-thru programming device or GM-specific scan tool (GM MDI/MDI2)
- GM special tool DT-45096 for flushing cooler lines
Budget for these consumables at install:
- DEXRON-VI synthetic automatic transmission fluid
- Control Valve Body Cover Gasket and connector seal (if swapping TEHCM)
- Front pump/torque converter seal
- Axle seals
- Professional-grade transmission cooler line flush or replacement plate-style cooler
What your vehicle’s computers will need after the swap:
What’s involved: VIN-specific dealer programming (using GM SPS2 software) AND a TCM Adaptive Relearn ('Fast Learn')
The internal TEHCM is locked to the donor vehicle's VIN. It must be reprogrammed using GM SPS2, or your original functioning TEHCM/valve body assembly must be swapped into the replacement unit. A TCM Adaptive Relearn ('Fast Learn') is mandatory in either case to calibrate the solenoids.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: The torque converter must be fully seated onto the input shaft and front pump (rotating and pushing until it drops/clicks three distinct times) before bolting to the engine. Forcing the bellhousing bolts will crack the pump rotor and destroy the transmission.
- Do Not Drop the Pan for the Filter: The main transmission fluid filter is internal and non-serviceable without completely splitting the transmission case.
- Fluid Level Checking Temperature: Fluid level must be checked with the engine idling, vehicle on level ground, and transmission fluid temperature strictly between 180°F and 200°F (82°C and 93°C).
- Cooler Line Contamination: You must flush the cooler lines or replace the plate-style cooler entirely to prevent debris from the failed transmission from destroying the replacement unit.
Easy to get right once you know them:
- Ordering the Wrong Drivetrain (AWD vs. FWD): Buying a FWD transmission for an AWD vehicle. The AWD version has a completely different case casting to accommodate the transfer case.
- Expecting Plug-and-Play Operation: Assuming the transmission will work without reprogramming the internal TEHCM or swapping the original TEHCM.
- Skipping the Cooler Line Flush: Failing to flush or replace the cooler, which leads to immediate failure from trapped metal debris.
- Forcing the Bellhousing Bolts: Using bolts to pull the engine and transmission together when the torque converter is not fully seated.
Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Reprogramming the TCM with updated software or replacing the torque converter if physical damage has occurred
🔎 Recommended at install: Reprogramming the TCM with the latest software calibrations
🔎 Recommended at install: Replace the control solenoid valve assembly and reprogram the TCM
🔎 Recommended at install: This 2017 Gen 2 unit features a redesigned, thicker, and stress-relieved wave plate from the factory, making failure highly unlikely.
🔎 Recommended at install: Replace or service the internal TEHCM/pressure switches

Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
