MONSTER TRANSMISSION FINDER
Step 1 of 7
What make is your vehicle?
We’ll start by narrowing you into the correct GM, Ford, or Dodge/Ram transmission family.
What best describes your vehicle?
This keeps us from, for example, putting a 68RFE on a Ram 1500 that actually runs an 8-speed.
What year is your vehicle?
We’ll map your year into the correct transmission era.
What engine are you running?
Options shown are filtered by your make + vehicle type + year.
Don’t see your exact engine? Pick “I’m not sure / engine swap.”
What drivetrain?
We’ll prioritize 2WD vs 4x4 coverage.
How do you use the vehicle?
Use case + HP tier determine your recommended build.
About how much horsepower?
Rough guess is fine — higher HP can override use-case.
Your Monster match
Based on your answers, here’s the build level and family you should be shopping.

Find the right Monster transmission for your Dodge / Ram
Choosing the right Dodge or Ram transmission comes down to three things: the transmission family, how the truck is used, and how much load it really sees. A stock daily driver does not need the same build as a Ram 2500 tow rig, a 6.7L Cummins work truck, or a hard-working chassis cab. This page keeps the process simple by helping you shop by tier first, then narrow down by the exact model family you need.
- Shop popular Dodge / Ram transmission families including 46RE, 47RE, 48RE, 545RFE, 62TE, 42RLE, 66RFE, 68RFE, and AS69RC.
- Choose a build tier that actually fits your use, from stock-style replacement to towing, diesel performance, and max-effort applications.
- Every complete package includes a matched torque converter, because lockup strategy and heat control matter just as much as hard parts.
- Helpful for Ram 1500, Ram 2500, Ram 3500, Ram 4500, and Ram 5500 shoppers who want a cleaner path to the right transmission.

Popular Dodge / Ram transmission families
Already know the transmission family you need? Start here. These links take shoppers straight into the right collection page instead of making them hunt for the right build.
46RE
A solid fit for older Dodge and Ram gas trucks or SUVs that need a dependable replacement for daily driving and light towing.
Shop 46RE →47RE
A go-to family for many 5.9L Cummins owners who want better towing confidence and a stronger diesel transmission setup.
Shop 47RE →48RE
Popular with Ram 2500 and 3500 diesel buyers who need a proven transmission for towing, work, or higher-demand Cummins use.
Shop 48RE →545RFE
A common choice for Dodge, Ram, and Jeep applications where smooth drivability, everyday dependability, and light towing matter most.
Shop 545RFE →62TE
Built for Dodge cars, vans, and crossover applications that need a clean stock-style replacement with dependable daily use in mind.
Shop 62TE →42RLE
A strong fit for Jeep and Dodge applications where buyers want a reliable replacement and a smoother path back on the road.
Shop 42RLE →66RFE
Common in HEMI Ram heavy-duty applications and a smart choice for buyers who tow, work the truck harder, or want more than stock-level confidence.
Shop 66RFE →68RFE
One of the most searched Ram transmission families, especially for 6.7L Cummins owners who tow, tune, or need a stronger long-term solution.
Shop 68RFE →AS69RC
Best for heavier-duty Ram 3500, 4500, and 5500 applications where commercial towing, RV use, hotshot work, or severe-duty load matters most.
Shop AS69RC →Not sure which transmission family fits your truck?
Many shoppers know the truck, the engine, or how they use it, but not the transmission code. This quick guide helps narrow things down before you jump into a collection page.
Ram 1500 daily driving and light towing
Often points toward 545RFE, 62TE, or 42RLE depending on the year and platform. These buyers usually want a clean replacement that keeps the truck or SUV easy to live with every day.
Older Dodge / Ram gas truck and SUV applications
Often tied to 46RE searches. A great fit for buyers replacing a worn factory unit in a daily driver, project, or utility vehicle.
5.9L Cummins Ram 2500 / 3500
Usually a 47RE or 48RE conversation. These buyers often care most about towing, line pressure, converter choice, and diesel durability under load.
HEMI Ram 2500 / 3500
Usually a 66RFE conversation. Best for customers deciding between a stock-style replacement and a stronger towing or work-truck upgrade.
6.7L Cummins Ram 2500 / 3500
Usually a 68RFE conversation. This is one of the biggest high-intent buying paths because these trucks are often used for towing, added power, or heavier-demand work.
Ram 3500 / 4500 / 5500 work trucks
Usually an AS69RC conversation. Best fit for commercial-duty, hotshot, RV, and harder-working truck applications where load matters more than just horsepower.
Final fitment should always be confirmed by year, engine, drivetrain, and VIN.
Choose the right tier for how you really use the truck
A daily-driver replacement and a heavy tow setup should not be shopping the same build. Be honest about towing, tire size, gearing, and added power before you choose a tier.
- RoadReady for stock-style replacement
- StreetMonster for towing and heavier everyday use
- SportMonster for higher-demand builds
- TrackMonster for max-effort setups
Transmission family matters just as much as the tier
A 47RE buyer, a 68RFE buyer, and an AS69RC buyer are usually solving three very different problems. Shopping by the right family first makes the whole process easier.
- 47RE / 48RE for many 5.9L Cummins paths
- 66RFE for HEMI heavy-duty trucks
- 68RFE for 6.7L Cummins pickups
- AS69RC for severe-duty Ram HD applications
Protect the build from day one
Most repeat issues after install come from contamination, skipped cooler service, bad fluid, or no relearn. A clean install gives the new transmission the best chance to live a long life.
- Flush or replace cooler and lines
- Use the correct fluid for the application
- Complete the proper relearn or drive cycle
- Do not skip converter seating checks
Quick install reminders for Dodge / Ram transmissions
Verify the converter is fully seated, confirm cooler flow, use the correct fluid, and complete the right relearn or adaptive drive cycle after install. These are the simple steps that help protect the transmission, the converter, and the customer’s investment.
Is the 68RFE a good transmission for towing?
Yes, when the build and converter match the truck’s real use. Towing, larger tires, and tuning can add a lot of hidden load, which is why the right tier matters.
Is the AS69RC better for heavy work?
For many commercial-duty and harder-working Ram applications, the AS69RC is a strong choice because those buyers usually care most about severe-duty towing and work-truck reliability.
Do I really need to flush or replace the cooler?
Yes. Contamination from the previous unit can damage the replacement quickly, so cooler and line service should never be skipped.
What is the best Dodge transmission for sale?
The best Dodge transmission is the one that matches the exact family, engine, year, drivetrain, and load your vehicle actually sees. This page is here to help narrow that down faster.
