Ensure the transmission matches your vehicle’s engine, drivetrain (4WD), year, and model.
-
Verify whether it’s 4×4-compatible and comes with the torque converter—if not, factor in the additional cost.
Warranty & Support

If you plan for towing, off-roading, or hauling heavy loads:
-
Invest in a high-quality transmission cooler.
-
Upgrade internal parts (sun shell, valve body, converter), especially on rebuilt units.
-
Consider stepping up to a 4L65E or 4L70E for increased torque capacity.
-
Maintenance Tips
-
Stick to service intervals: fluid/filter every 50,000 miles under severe duty; otherwise 100,000 miles
-
Use Dexron VI transmission fluid or quality synthetic equivalents.
-
Replace filters and inspect for metal shavings or burnt smell before buy.
