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 the engine is a 3.5L V6, not a V8 Hemi or 3.6L Pentastar.
- Verify the current transmission is a 5-speed automatic (NAG1) with AutoStick, not a 4-speed (42RLE).
- Confirm the vehicle is Rear-Wheel Drive (RWD).
- Check the passenger side front corner of the transmission pan for signs of fluid leaks from the round electrical plug.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Mopar Special Tool 9336 / 9336A (Transmission Fluid Dipstick Tool)
- OBD2 Scan Tool / Infrared Thermometer
- Torx T30 socket
- 5mm Allen socket
- 7mm socket
Budget for these consumables at install:
- Mopar ATF+4 (Licensed MS-9602)
- Transmission filter and pan gasket kit
- Front pump / input shaft seal (torque converter seal)
- 13-Pin Connector Plug Sleeve (Guide Bushing, Mopar 68021352AA)
- Professional cooler-line flush solvent
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn (Drive Cycle Adaptation)
sources differ: Arm 1 states programming is not required for basic operation but recommended, while Arm 2 states it is required. A professional-grade or dealer-level scan tool (like Mopar wiTECH) is required to reset TCM shift adaptives and perform the drive cycle adaptation.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque converter must be fully seated with three distinct clicks/drops to avoid cracking the front pump gear upon engine mating.
- The 13-pin connector sleeve center 7mm bolt must not be over-tightened (torque spec is only 2.5 Nm / 22 in-lbs) to avoid stripping the brass nut in the conductor plate.
- Shifter linkage pin must align perfectly with the manual valve on the valve body.
- Ensure both engine block alignment dowel pins are in place to prevent crooked seating.
- Fluid level must be checked using the special dipstick tool and cross-referenced with a temperature-to-fill-height chart via OBD2 temperature readings.
Easy to get right once you know them:
- Using the wrong fluid (such as Mercedes-spec or generic multi-vehicle ATF) instead of Mopar ATF+4.
- Over-tightening the 13-pin connector plug bolt and ruining the internal conductor plate.
- Checking fluid level without the special dipstick tool, checking it cold, or leaving the tool inside the fill tube permanently.
- Reusing the old leaking 13-pin connector plug sleeve, which can wick fluid into the TCM and destroy it.
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: Perform a thorough triple flush of the transmission and torque converter, replace the filter, and apply sealant to the base of the fill tube.
🔎 Recommended at install: Replace the internal conductor plate (lead frame) when speed sensors fail and trigger limp-home mode.
🔎 Recommended at install: Replace the 13-pin electrical connector sleeve and its O-rings to prevent fluid from wicking into the wiring harness and TCM.
🔎 Recommended at install: Refer to Chrysler Recall K08 to address ignition key removal binding before shifter is in Park.
🔎 Recommended at install: Perform software updates for the Transmission Control Module (TCM) to address DTC P0730 and improve shift quality.

- 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

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

- 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.
