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 transmission model number on the driver's side identification tag is explicitly marked '8HP70'.
- Confirm the vehicle is Rear-Wheel Drive (RWD).
- Confirm the vehicle has a 5.7L Hemi V8 engine.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Transmission jack
- Fluid transfer pump
- Professional-grade scan tool (wiTECH, AlfaOBD, or equivalent)
- Digital leveling tool
- Engine support bar
Budget for these consumables at install:
- ZF Lifeguard 8 fluid or Mopar 8&9 Speed ATF (Shell L12108 / Part # 68218925AB)
- Replacement integrated plastic transmission oil pan and filter assembly
- 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 security alignment and TCM adaptive Quick Learn
The integrated TCM is locked to the donor vehicle's VIN. The installer must perform an EGS/TCM alignment to write the new VIN using a dealer-level tool (wiTECH) or advanced software (AlfaOBD/HP Tuners). A 'Quick Learn' adaptive reset must also be performed to clear old clutch adaptation values.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque converter must be fully seated into the front pump (feeling 2-3 distinct drops) before bolting the transmission to the engine. Forcing it will crack the pump and destroy the unit.
- The final fluid level check must be performed with the engine running and the transmission fluid at a specific temperature (30-50°C) while the vehicle is perfectly level.
- The transmission cooler and lines must be thoroughly flushed to prevent debris from the failed unit from contaminating the replacement transmission.
- Do not skip the electronic Quick Learn procedure, as the transmission may shift harshly or erratically without it.
Easy to get right once you know them:
- Failing to properly seat the torque converter, resulting in a cracked front pump during installation.
- Using incorrect transmission fluid such as ATF+4, Dexron, or generic multi-vehicle fluids instead of ZF Lifeguard 8 / Mopar 8&9 Speed ATF.
- Skipping the transmission cooler and line flush, leading to immediate contamination and premature failure.
- Neglecting the mandatory electronic adaptive relearn procedure after installation.
- Purchasing an incompatible 8HP70 variant from a Ram 1500, Jeep, or AWD vehicle.
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: Dealer must inspect and install the correct park lock rod to prevent unintended vehicle movement.
🔎 Recommended at install: Inspect and repair fluid leaks around the transmission oil pan gasket, output shaft seal, or cooler line connections.
🔎 Recommended at install: Reprogram the TCM with the latest software updates and perform the Adaptation Drive Learn Procedure.
🔎 Recommended at install: Typically normal behavior that resolves once the transmission fluid reaches operating temperature.
🔎 Recommended at install: Reset the transmission's adaptive learning values using a scan tool.
🔎 Recommended at install: Regular fluid maintenance, or replacement of clogged solenoids/Mechatronic unit if slipping or gear ratio errors occur.

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

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

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

- 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.
