Ford 10R80 Transmission Frequently Asked Questions
Answers to common questions about fitment, upgrades, installation, warranty and the refundable core deposit.
Which Monster 10R80 should I choose for a stock F-150?
RoadReady is built for a stock-power F-150 that needs a complete replacement. Choose StreetMonster if the truck regularly tows, runs larger tires, carries added load or has mild power upgrades.
What is the difference between RoadReady and StreetMonster 10R80?
RoadReady is focused on stock replacement. StreetMonster adds a revised CDF drum with retaining feature, upgraded remanufactured valve body, upgraded converter friction and a deep aluminum pan, and is rated for approximately 100 horsepower over stock.
How long is the warranty on Monster 10R80 transmissions?
Both RoadReady and StreetMonster 10R80 transmissions include a 3-year unlimited-mile Monster warranty. Eligible purchases can add Extend protection for total coverage of up to 6 years.
Does the Monster 10R80 include a torque converter?
Yes. The RoadReady and StreetMonster 10R80 transmissions on this page include a matched torque converter.
What vehicles use the 10R80 transmission?
The 10R80 is used in many Ford F-150, Mustang, Expedition and Lincoln Navigator applications. Exact year, engine and drivetrain fitment varies, so use the vehicle selector above or confirm by VIN.
How much horsepower can the StreetMonster 10R80 handle?
Monster currently rates the StreetMonster 10R80 for approximately 100 horsepower over stock. Vehicle weight, torque, tire size, tuning and how the vehicle is used also affect transmission load.
What is the 10R80 CDF drum problem?
Movement of the CDF clutch-cylinder sleeve can contribute to hydraulic pressure loss, shift flare, delayed or harsh shifts and clutch damage. StreetMonster uses a revised CDF drum with a retaining feature as part of its upgraded build.
What fluid does a 10R80 use?
Monster specifies Ford MERCON ULV for the 10R80. Use the correct fluid and follow the proper temperature-based level-check procedure after installation.
How much fluid does a StreetMonster 10R80 take?
StreetMonster product information specifies approximately 16 quarts of MERCON ULV with the deep-pan setup when dry. Actual service fill can vary, so set the final fluid level using the correct procedure.
Does a replacement 10R80 need programming?
Yes. The correct solenoid-body strategy and ID information, module setup and adaptive reset must be completed after installation with a capable Ford scan tool or equivalent.
Does the 10R80 need an adaptive relearn after installation?
Yes. After programming and strategy setup, complete the proper adaptive relearn and drive cycle so the control module can learn clutch fill and shift behavior.
Should the transmission cooler be flushed or replaced?
The cooler and lines must be properly serviced after a transmission failure so debris does not enter the replacement unit. Follow Monster's current installation requirements; replacement may be required when proper heated back-flushing cannot be completed.
Does the StreetMonster 10R80 fit every Ford Raptor?
No. Current StreetMonster fitment information includes 2017 and 2021-2024 10-speed Raptor models but excludes 2018-2020 Raptors. Confirm current fitment before ordering.
Does the StreetMonster 10R80 fit a ROUSH F-150?
Current Monster StreetMonster 10R80 fitment information states that it does not fit ROUSH F-150 applications.
How does the refundable core deposit work?
A refundable core deposit applies to eligible 10R80 purchases. You can pay it with your order or after checkout. If you pay later, Monster will contact you before shipment. After an eligible matching core is returned and accepted, the deposit is refunded less any applicable return shipping or handling amount.
