Description

OEM REPLACEMENT

48RE Transmission Rebuild Process

The 48RE torque converter is upgraded with a billet cover and precision-machined mounting pads exceed OEM specifications, eliminating common issues like front seal leaks, premature bushing wear, and driveline vibration. Each torque converter is rigorously tested for leaks, lockup function, concentricity, and balance to ensure optimal performance. Designed for both diesel and heavy-duty gasoline applications, this unit features a new heavy-duty lock-up lining for improved torque transfer. The upgraded valve body includes an enhanced throttle valve, manual valve, 4-spool switch valve, and pressure regulator valve, all working together to deliver smoother shifting, improved lubrication, and enhanced overall performance. In addition, the valve body is modified to support torque converter charging in Park, boosting durability and providing smoother gear engagement.

The remanufactured pump assembly ensures consistent internal line pressures, eliminating slipping and delayed engagement issues. The High/Reverse clutch is upgraded to a 4-plate configuration for both gas and diesel applications, while the Overdrive (OD) direct clutch is enhanced with a 10-plate setup and updated thrust plate for increased durability. The Overdrive planetary assembly is upgraded to a 5-pinion unit, offering superior load capacity and longevity. The OD clutch is further upgraded to a 4-plate configuration for gas engines and a 5-plate clutch for diesel engines. An oversized Low/Reverse brake band strut is installed to maintain proper band clearance, effectively eliminating drum slippage and “no-reverse” conditions. Precision-fit SP-spec 48RE bushings are installed as needed to enhance internal fluid flow and pressure control. All bushings and machined surfaces are polished to a mirror-like OE finish of 16 RA or better, ensuring top-tier reliability and long-term performance.

Core Deposit

Helping us give you the best prices available.

This part is sold at a price based on a rebuildable core being returned to us. The recycled metals and components can assist the manufacturing process keeping our prices to an all time low. This temporary deposit is withheld to ensure that we receive your damaged unit.

How is the core deposit charged?

How is the core deposit charged? At the time of purchase the core deposit will be added to the customers total. Once the core is received and processed at our facility, the deposit will then be issued back to the customer.

How long do I have to return my core?

To receive a full deposit your core must be received within 30 days after the delivery of your part. Late fees may be assessed to cores that are returned beyond 30 days from the customers original purchase date. Any extensions must be proved by a sales manager.

Refund Time?

Orders are typically refunded back onto the credit card within 1-3 weeks after the core arrives. Check orders will be mailed back. Call to verify arrival if you have not been refunded within your 3 week window.

How do I return the core?

In most situations your unit will be delivered with a shipping form called the “Bill of Lading”. You or your shop can send the core back with the delivery driver or at a later date by calling the shipping company to schedule a pickup. Be sure to use our shipping form or the shipping company may bill you personally. If your form has been lost or misplaced you will have to call our shipping department to generate a replacement.

Bad or missing core?

If there is no core to exchange, in most cases we can just add the deposit amount to the purchase price. In addition, you will only be required to pay a one way shipping fee. In the case that our stock becomes low on a certain core, we may charge an increased amount for the core when there is not one to exchange. In the rare case a core becomes critically low we reserve the right not to sell a product without a core exchange.

Can I send my core first?

On manual transmissions, engines and transfer cases you can send us your core before we send out your unit. By doing this overall shipping may take longer but you will not be required to pay a core deposit just shipping and the price of your part.
