How a Automatic Transmission is Made

Wednesday, September 21st, 2011

The remanufacturing process of a BOSS Transmission starts with the proper identification of the transmission. The used transmission core is then disassembled, washed thoroughly using biodegradable cleaning solutions, in an industrial, high-temperature transmission parts washing machine. Each internal part is inspected thoroughly for OEM specifications. All parts not meeting OEM specifications are discarded and replaced using a variety of quality new OEM and aftermarket parts, such as Honda, GM, Chrysler, and Ford OEM and other parts providers.

We use aftermarket new parts, such as Borg Warner, Transtec, Sonnax, Raybestos, Precision, and Rostra, just to name a few. Each transmission unit is carefully re-assembled and updated using the latest technical service specifications, such as, valve body re-programming, super-ceded parts replacement, bushing updates, electronic updates, torque converter bearing and lining updates, all of which are required to meet BOSS Transmissions building standards. Each of our transmissions are built by a knowledgeable and experienced transmission technician from start to finish, ensuring a quality tested rebuild remanufactured transmission. It is then ready for you to replace that old and non-working transmission with a quality tested rebuild or remanufactured BOSS Transmission.

4L60E Automatic Transmission Shift Kit

Saturday, September 17th, 2011

Before you rebuild your 4L60E Transmission you will need a rebuild kit. Most higher end rebuild kits will include a new shift kit as well.

AOD Transmission Oil Pump and Piston Assembly

Tuesday, September 13th, 2011

The AOD (for automatic overdrive) is a four-speed automatic transmission with overdrive. Introduced in 1980, it was Ford’s first four-speed automatic overdrive transmission. The 4R70W stands for 4 gears, Rearwheeldrive, 70 stands for the 4th gear ratio, and Wide gear ratio. It has lower 1st and 2nd gear ratios for better take-off acceleration and improved gearset strength.

The AOD was used originally on ’80s and early-’90s Ford, Lincoln, and Mercury products and in the F-series pickups and E-series vans as well. Because the AOD is basically a retooled C-4, many classic car owners have discovered they can substitute this overdrive transmission into their ’60s and ’70s production vehicles relatively easily and reap the benefits of a lower final gear ratio and decreased wear and tear on their vintage small-block V-8 engine. Theres more parts to take off of this but I will do that when the rebuild kit gets here, just to make sure I get the right parts.
