Helpful Fitment Notes
- Identify your transmission: Most 2500 models use 68RFE; many 3500 HO applications use the Aisin AS69RC. Confirm by VIN and the tag on the case to match parts correctly.
- Power & use case: Choose converters, clutch packs, and billet shafts based on torque goals (towing, daily, race). Higher power and heavy towing benefit from multi-disc converters and upgraded frictions.
- Cooling capacity: Deep pans add fluid and heat capacity; auxiliary coolers and upgraded lines help manage temps while towing or in hot climates.
- Electronics & relearn: After valve body, converter, or solenoid work, perform the proper teach-in/relearn procedure to optimize shifts and prevent flare/harshness.
- Fluids: Always use the fluid type and fill procedure specified on each product page and in your owner’s/service manual. Check level with the truck on level ground.

Transmission & Drivetrain FAQ – 2019–2024 Ram 2500/3500
How do I know if I have a 68RFE or Aisin AS69RC?
Check your build sheet/VIN and the tag on the transmission. 2500 models commonly use 68RFE; many 3500 HO trucks use the Aisin. Match parts by the exact code on your tag.
Do I need tuning or a relearn after installing a converter or valve body?
A relearn/teach-in procedure is recommended after major hardware changes. Follow the product and service manual steps so shift quality adapts correctly.
Will a deep pan help transmission temps while towing?
Yes—added fluid and increased surface area improve heat capacity. Pairing a deep pan with an upgraded cooler/lines offers the best temperature control under heavy load.
When are billet shafts or SFI flexplates necessary?
High torque, aggressive launches, or competition use can exceed OE margins. Billet shafts and SFI flexplates add safety and reliability for big power or racing classes that require them.
Which fluid should I use and how do I check level?
Use the fluid type and procedure specified for your transmission and the products you install. Check level with the vehicle on level ground and at the temperature indicated in your service manual.
