ABOUT THIS PRODUCT

The 66RFE transmission shares many pain points with its 68RFE sibling—valve body cross-leaks, worn SSV (Solenoid Switch Valve) bores, and overdrive (OD) clutch failure that shows up as slip, heat, and early wear. The Monster StreetMonster 66RFE fixes the root causes with an upgraded valve body featuring a billet steel–sleeved SSV bore for tight, leak-free operation and a gasketed separator plate that prevents cross-leaks from bleeding off OD apply pressure. Paired with a Heavy-Duty torque converter, this build delivers cooler temps, firmer apply, and long-term reliability for stock to mildly upgraded HEMI-powered Ram 2500/3500 trucks.

Frequently Asked
When Will My Transmission Ship?

In-stock transmissions usually ship the next business day.

Custom builds or out-of-stock units typically ship within 2–4 weeks.

Need it sooner? Call us — we can often make special arrangements.

We offer the most comprehensive coverage in the industry:

  • StockMonster: 1 Year (Extendable to 4 Years with Extend)
  • StreetMonster: 2 Years (Extendable to 5 Years with Extend)
  • SportMonster: 3 Years (Extendable to 6 Years with Extend)

Is Shipping Cheaper if I Use a Commercial Address?

No — we offer a $299 Flat-Rate One-Way Shipping to any address, commercial or residential.

If you find a better rate, you're welcome to arrange your own shipping.

Does this Transmission include Fluid?

No — fluid must be purchased separately. We offer special discounted prices and even cheaper shipping options when you bundle with our fluid at checkout.

How do I Return my Old Transmission Core?

Returning your core is simple. Once you are ready to return your core, you can initiate the return process in one of two ways:

  • Fill out our Core Return Form (available online) using the button below.
  • Or call our Customer Service Team at 800-708-0087 to schedule your return freight pickup.

Please Note:

  • The customer is responsible for the return shipping cost.
  • A flat-rate fee of $299 will be deducted from your core refund to cover return freight and handling. If Round Trip Shipping is not Prepaid Upfront.
  • The core must be the same model and not cracked or damaged beyond rebuild.

Our goal is to make this process as seamless as possible — if you have questions about your core return, just give us a call.
