Every part we use will be verified to meet or exceed the Original Equipment Manufacturer (OEM) spec.
Even though the 4L85E transmission has been known to be fairly reliable, no transmission is without its occasional factory defects and flaws.

Our 4L85E Transmission Upgrades
Fully remanufactured valve body, with complete system correction and recalibration kit, improves pressure control and shift quality.
Upgraded actuator feed limit valve prevents missing shifts and premature transmission failure.
Upgraded 34 element intermediate sprag increases holding capacity.
All-new shift solenoids ensure positive shifting.
EPC solenoid is tested separate from the transmission to confirm precise pressure control.
Updated force motor for improved pressure control.
Updated pressure regulator prevents overly high pressure.
Case connector is updated to the latest design on pre-1994 versions, and a vehicle harness pigtail is provided to address connection issues with the early design.
Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
No Walkout rear case bushing is installed, addressing an OE flaw, to prevent case and output shaft damage.
All-new custom-spec bushings to improve internal fluid flow control and pressures.
Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.
4L85E Frequently Asked Questions
How much horsepower can a 4L85-E handle?
A stock 4L85-E transmission typically handles 400-500 horsepower. With a remanufacturing process like ours, a 4L85-E transmission can be slightly modified to handle over 1,000+ HP all the way up to 1500 HP with significant mods, offering your vehicle a significant boost in power handling and performance tuning.
What’s the difference between a 4L60E and 4L85E transmission?
The 4L80E is more abundantly used in heavy-duty vehicles commonly equipped with big-block engines, diesel engines, and 4WD because of its heavier duty internal components which can be seen in a simple weight comparison. For example, the 4L60E only weighs approximately 150 pounds total while the 4L85E weighs almost 180 pounds and that’s without fluid.
What’s the difference between 4L80E and 4L85E?
The 4L80E has a lock-up torque converter, overdrive top gear, and better electronic controls. The 4L85E contains many of the same components as a 4L80E but is rated at a staggering 690 ft-lb while the 4L80E is rated at 440 ft-lb. Most of the increased power handling capability the 4L85E has comes from its five pinion gears versus the four in the 4L80E.
Is the 4L85E an Allison transmission?
No, the 4L85E is not a transmission manufactured by Allison, but rather, is manufactured by General Motors (GM). It is possible to replace or interchange a 4L85E transmission with an Allison transmission or get your 4L85E rebuilt or remanufactured by our expert team.
4L85E History & Information
The 4L85-E (a heavier-duty version of the 4L80-E) is an automatic transmission from General Motors (GM) originally designed for longitudinal engines. The 4-speed 4L85-E came about as an electronically controlled, improved version of the 3-speed Turbo-Hydramatic 400 (TH400) that came out in 1963. These transmissions were originally built at the Willow Run Transmission factory in Ypsilanti, Michigan. It should be noted that the 4L85E is the most heavy-duty transmission produced out of the 4L series General Motors transmissions which also includes the 4L60E, 4L65E, 4L70E, 4L75E, and 4L80E. It should be noted that the successor to this transmission is the GM 6L80 transmission. The 4L85E has been used with the NV246, NV261, and NV263 transfer cases but most commonly the 246.
The 4L85-E (GM Regular Production Option (RPO) MN8) is rated all the way up to 690 ft-lb of torque compared to the lighter-duty 4L80-E that’s only rated at 440 ft-lbs. Vehicles with a Gross Vehicle Weight Rating (GVWR) of up to 18,000 lbs can utilize the 4L85E, with the only exceptions being the type of vehicle and its axle ratio.
Several notable heavy-duty vehicles that utilize the 4L85-E transmission include:
- Chevrolet Suburban 8.1 Vortec
- Chevrolet Avalanche 8.1 Vortec
- Chevrolet Express (Duramax Diesel) or 8.1 Vortec 2500/3500
- Local Motors 2009 Rally Fighter
- GMC Savana with Duramax Diesel or 8.1 Vortec
- GMC Yukon XL 8.1 Vortec
Since the 4L85E is an impact-driving and heavy-duty transmission that’s proved reliable over the decades, many vehicle owners want a 4L85E transmission in their vehicle either through a swap, rebuild, or a bought used transmission from a high-quality transmission provider like our shop.
If you’re interested in obtaining a 4L85E for your vehicle or rebuilding one of your existing 4L85Es, we’re available to help.
