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:
- Confirm that the 8th digit of your VIN is W (which designates the 3.6L V6 engine, option code LFY).
- Verify your Drivetrain: Look at your center console for an AWD selector knob, or check for an AWD badge on your tailgate. This transmission is for FWD models only.
- Scan the QR code label on your driver's door B-pillar. Look through the listed RPO codes for M3V. If you see M3W, your vehicle is AWD and you cannot use this unit.
- Open your glove box and find the 'Service Parts Identification' sticker to verify the RPO code is M3V.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support fixture / support bar
- Transmission jack
- Subframe alignment pins
- GM-compatible J2534 pass-thru tool or GM MDI scan tool
- Torque wrench
- Extensive socket and wrench sets
Budget for these consumables at install:
- ACDelco DEXRON-VI Full Synthetic Automatic Transmission Fluid (approx. 10.0 to 11.0 Quarts for a dry fill)
- Axle/output shaft seals
- Torque converter seal
- Side valve-body cover gasket (if side cover is opened)
- Transmission cooler-line flush
What your vehicle’s computers will need after the swap:
What’s involved: Solenoid Characterization Programming (MCVM) / TCM Adaptive Relearn
The Transmission Control Module (TCM) must learn the new unit's specific hydraulic characteristics (known as the Transmission Unique Number or TUN). You must use GM's Techline Connect / SPS2 programming system to download the characterization data file matching your replacement transmission's TUN and flash it into your vehicle's TCM. Failing to do this will result in harsh shifting, slipping, immediate trouble codes, and rapid clutch destruction.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Write Down the TUN Before Installation: The 16-digit Transmission Unique Number (TUN) is printed on the barcode sticker on the transmission case. You must write this down or take a clear photo of it before bolting the transmission into the vehicle. Once installed, this tag is completely hidden and inaccessible.
- Torque Converter Seating: Ensure the torque converter is fully pushed back and rotated until it completely engages the front pump gears (it will 'clunk' into place two or three times). If it is not fully seated, bolting the transmission to the engine block will instantly crack the front pump, destroying the unit.
- Strict Fluid Level Check Procedure: The 9T65 has no dipstick. The fluid level must be checked with the transmission at a specific operating temperature (85°C to 95°C / 185°F to 203°F) and the engine running, after cycling through the gears, by removing the level check plug on the side of the case.
- Mandatory Cooler-Line Flush: Because 9T65 failures often involve torque converter clutch disintegration, your existing cooler lines are likely contaminated with fine metal and friction debris. You must thoroughly flush the lines to prevent this debris from washing into and destroying your replacement transmission.
- Auto-Stop Feature Hazard: On some Traverse models, the engine has an auto-stop feature that can activate after 10 minutes of idling. If this happens while you are checking the fluid level with the level plug removed, a large amount of fluid will pour out.
Easy to get right once you know them:
- Ordering for an AWD Vehicle: Buying this FWD transmission (RPO M3V) for an AWD Traverse (RPO M3W). They look similar but the AWD version has a completely different case casting to mount the transfer case.
- Skipping the Solenoid Programming: Assuming a used transmission is 'plug and play' and skipping the dealer programming step. This will immediately trigger shift flares, slip codes, and can burn up the clutches within a few miles.
- Reusing Contaminated Cooler Lines: Skipping the cooler line flush, which introduces debris from the old failed unit into the replacement, causing a repeat failure.
- Checking Fluid Level Cold: Checking the fluid level while cold or with the engine off, which leads to a massive underfill and subsequent slipping and overheating.
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: Over time, the composite checkballs inside the valve body degrade, shrink, and are hammered directly through the spacer/separator plate. This causes an immediate loss of reverse gear, slipping, or a 'tied-up' binding sensation when shifting into reverse, often throwing trouble code P2723.
🔎 Recommended at install: Addressed in GM TSB PIP5608H, the friction material on the factory torque converter clutch is prone to premature degradation. This causes a noticeable 'shudder' or vibration at low RPMs (typically 1,300–1,500 RPM at highway speeds). If left unaddressed, the disintegrating clutch material contaminates the fluid, clogs the solenoids, and ruins the valve body.
🔎 Recommended at install: The start-stop accumulator endcap may have been manufactured with missing bolts. This can lead to a sudden, severe transmission fluid leak, resulting in a loss of propulsion and a potential fire hazard.
🔎 Recommended at install: Covers complaints of transmission slipping or flaring on the 1-2 upshift under zero to very light throttle input, and/or a flashing 'D' (Drive) indicator on the instrument panel. This is typically resolved with a TCM software update and/or a fluid flush and replacement.
🔎 Recommended at install: Symptoms include hesitation or a slip/flare during the 1-2 upshift, feeling like the vehicle is in neutral at highway speeds, harsh shifting, and a flashing 'D' on the gear display. Some forum users report this is caused by a failing snap ring inside the transmission, which contaminates the valve body and torque converter with debris.
🔎 Recommended at install: Transmissions built with an incorrect sun gear could cause the driver-side half-shaft to disengage, leading to a loss of drive power or a rollaway when in Park.
🔎 Recommended at install: A screw holding a plastic wheel-well shroud could rub against the transmission case, potentially causing a fluid leak. Applies only to vehicles modified by BraunAbility for wheelchair access.
🔎 Recommended at install: On a very small number of 2019 Traverse vehicles, the axle seal bore in the transmission housing was machined too large, which could cause a fluid leak. The fix was to replace the torque converter housing.

Policies, in plain English.
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)

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.
