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 VIN 8th digit is 'A' (confirms 2.5L LCV engine).
- Verify VIN 5th digit or physical presence of front CV axles and transfer case (confirms 4x4).
- Verify RPO code 'MYB' and 'LCV' on the Service Parts Identification sticker in the glove box.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Heavy-duty transmission jack
- Transfer case jack or support
- Torque wrench
- Fluid transfer pump and fill adapter
- GM-specific scan tool (GM MDI or equivalent J2534 pass-thru)
Budget for these consumables at install:
- Mobil 1 Synthetic LV ATF HP or high-quality licensed Dexron VI fluid
- Transmission filter and pan gasket kit
- Torque converter seal (front pump seal)
- Transmission cooler flush solvent
What your vehicle’s computers will need after the swap:
What’s involved: VIN-specific programming and TCM Adaptive Relearn ('Service Fast Learn Adapts')
The internal TEHCM must be programmed with the vehicle's specific VIN and software calibration using GM's Service Programming System (SPS) and a J2534 pass-through device. Alternatively, the original working TEHCM can be physically swapped into the replacement unit. A 'Service Fast Learn Adapts' procedure must be performed post-install to prevent clutch damage.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must feel three distinct drops/clicks during installation. Converter pads must sit recessed approx 1.0 inch back from the bellhousing face. Improper seating will destroy the fluid pump.
- No-Dipstick Fill Procedure: Fluid level must be checked via the level control plug in the bottom of the pan with the engine idling, vehicle level, and fluid temperature strictly between 85°F and 113°F (30°C to 45°C).
- Cooler and Line Flush: Must perform a high-pressure chemical flush of the cooler lines to prevent trapped debris from destroying the replacement unit.
- Dowel Pin Alignment: Ensure engine block alignment dowel pins are clean and in place to prevent pump bushing wear, leaks, or cracked flexplates.
Easy to get right once you know them:
- Ordering a 2WD transmission for a 4x4 truck (output shafts and tailhousings differ significantly).
- Skipping the transmission cooler line flush.
- Failing to perform the 'Service Fast Learn Adapts' procedure before driving.
- Checking the fluid level at the wrong temperature (above 113°F/45°C leads to underfilling).
- Assuming the transmission is plug-and-play without planning for TEHCM/TCM programming.
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: Complete transmission fluid flush using updated Mobil 1 Synthetic LV ATF HP fluid. If unaddressed, torque converter replacement is required.
🔎 Recommended at install: Update TCM calibration and perform fluid flush.
🔎 Recommended at install: Remove and service the valve body to address stuck rubber check ball in separator plate.
🔎 Recommended at install: Reprogram the Transmission Range Control Module (TRCM) with updated calibration.

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)
- 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.
