BD Ford E4OD Performance Transmissions
From street and towing to full race, BD Builds Them Best!
To some it is a challenge to simply disassemble and assemble a Ford transmission. For BD, the challenge was to improve the durability and performance of these transmissions in demanding, high-torque diesel applications.
The smooth shifting associated with the stock Ford transmission is the result of slippage that produces heat and accelerates wear. BD transmission and converter clutches are made from specialized, high-performance materials, and 33% more clutch surface is added to eliminate slippage.
A re-programmed valve body with improved valve designs, higher line pressure and enhanced oil flow creates positive clutch apply, which results in quick, sharp shifts. A BD deep-sump aluminum pan is also fitted, which increases oil capacity for cooler operation.
The planetary gear packs are made from high-strength steel, and heavy-duty, one-way roller Sprague clutches maintain directional stability, unlike the stock or inferior aftermarket products, which can explode.
Finally, each transmission’s shift pattern and oil pressure is tested on our transmission dynamometer, then shipped to you in a virtually indestructible molded plastic container. For ultimate strength and reliability, we recommend you match your new BD transmission with a TorqForce performance torque converter.
Our transmission packages include an auxiliary full flow filter kit for the 1990-2003 7.3L.
NEW WARRANTY : 36-month / 150,000 mile limited warranty on non competitive, racing or sled-pulling applications. See warranty statement for further details
Note: If your truck has PTO provisions, please make note of this in the comments section.
CORE CHARGES – PLEASE READ
LOWER 48 STATES
We give you the option of deferring the upfront core charge for transmissions shipped within the lower 48 states. The core must be returned within 21 days or your credit card will be charged for the full core amount.
For purchases out of the lower 48 states an upfront core charge is REQUIRED, please call if you have any questions.
SHIPPING POLICY – PLEASE READ
Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. For this reason, we cannot offer free shipping on transmissions. However, we do offer a service for each of our BD transmission sales that involves us coordinating the shipment of your core transmission back to BD, taking out the guess work for you. So how it works is we charge an upfront flat rate charge at the time of sale for shipping BOTH ways. We have also broken down the shipping charges as to whether we are shipping to a commercial or residential address. It is drastically less expensive to ship to and from a commercial address, so we recommend having it shipped as such. The commercial address does NOT need to be a service shop, it can be nearly any commercial address to take advantage of the cost savings. Please choose from the drop down menu as to what type of address the transmission will be shipping to and from. Finally, once your core transmission is ready to be picked up, you just need to give us a call with your original order number and the core tag on the transmission, and we’ll take care of the rest. As always, if you have any questions, give us a call or send us an e-mail.
