The automatic transmission assembly with reference number RL070942AC is designed for the Chrysler 62TE 6-speed automatic transaxle. Engineered specifically for front-wheel-drive minivans and commercial vans, this robust unit features an integrated final drive and a compound gearset, delivering smooth shifting and reliable load-carrying capability for the Chrysler Town & Country, Dodge Grand Caravan, and Ram ProMaster.
Quick Specifications:

Applications:
-
Chrysler Town & Country (2008-2016, 3.6L/3.8L/4.0L V6 variants)
-
Dodge Grand Caravan (2008-2020, 3.6L/3.8L/4.0L V6 variants)
-
Ram ProMaster (2014-2021, 3.6L Pentastar V6 FWD commercial van variants)
-
Volkswagen Routan (2009-2014, 3.6L/3.8L/4.0L V6 variants - rebadged minivan)
Complete Assembly Includes:
✅ Aluminum transmission case with planetary gearsets and integrated final drive/differential
✅ High-capacity torque converter with lock-up clutch
✅ Valve body with integrated solenoid pack and pressure regulators
✅ Clutch packs (Underdrive, Overdrive, 2nd/4th, Low/Reverse), bands, and oil pump
✅ Input/Output speed sensors, range selector (TRS), and sealing gaskets
✅ External TCM interface (Transmission Control Module is typically integrated into the vehicle's PCM)
Note: Transmission mounts, shift cables, axles (half-shafts), and external cooler lines may need to be transferred from the original unit.
Key Features:
✅ Compound Gearset Design: Evolved from the legendary 41TE 4-speed platform, adding a compound gear section to achieve 6 forward speeds without significantly increasing the transaxle's physical size.
✅ Integrated Final Drive: Houses the differential and final drive gears internally, optimizing packaging for transverse FWD minivan and van platforms.
✅ Heavy-Duty Clutch Capacity: Reinforced clutch packs designed to handle the weight of fully loaded minivans and commercial cargo vans (Ram ProMaster).
✅ Adaptive Shift Logic: The PCM/TCM continuously monitors clutch volume and shift times, adapting line pressure to compensate for normal clutch wear over the life of the vehicle.
Technical Notes:
Critical Installation Requirements:
-
Fluid Specification: Must use Mopar ATF+4 exclusively. Using Dexron, Mercon, or incorrect fluids will cause severe shift flaring, torque converter shudder, and rapid clutch degradation due to incompatible friction modifiers.
-
Quick Learn Procedure: After installation, a "Quick Learn" procedure must be performed using a Chrysler wiTECH or equivalent diagnostic scanner. This forces the TCM to relearn the clutch volume indices (CVI) and shift adaptives; skipping this will result in harsh or slipping shifts.
-
Cooler Flushing: The transmission cooler (integrated into the radiator) and external lines must be thoroughly flushed. Debris from a failed 62TE can easily clog the new solenoid pack and valve body.
-
Axle Installation: Care must be taken when inserting the front CV axles into the differential side gears to avoid cutting or displacing the internal seals.
Common Issues & Maintenance:
-
Solenoid Pack Failure: The external solenoid pack (mounted on the front of the transmission case) is a known wear item. Failure often triggers limp mode (stuck in 2nd gear) and sets pressure switch rationality codes.
-
Underdrive Clutch Wear: Aggressive driving or low fluid levels can lead to premature wear of the underdrive clutch hub or friction plates, resulting in a loss of forward gears.
-
Fluid Level Sensitivity: The 62TE is highly sensitive to fluid levels. Both overfilling (causing foaming and aeration) and underfilling (causing pump cavitation and slip) will lead to immediate drivability issues.
-
Fluid Service Intervals: A drain and fill with Mopar ATF+4 every 60,000 km is strongly recommended, especially for Ram ProMaster commercial vans or minivans frequently used for towing and heavy hauling.
