Turn that 4R70W automatic transmission in your 1996-1999 Mustang into a heavy-duty work horse or a competitive unit for the street or strip with B&M's Shift Improver Kit! This kit was designed by B&M to provide firm positive shift quality and improve the overall durability of the 4R70W transmission.
Shift Improver Kit Features and Benefits:
- Recalibrates the 4R70W for Optimum Performance and Extended Life
- Two Stage Kit In One Package: Heavy Duty or Street/Strip
- Transforms Soft and Sluggish Shifts into Crisp, Precise Shifts
- Eliminates Shift Overlap
- Reduces Clutch and Band Wear
- Installation Only Requires Simple Hand Tools
You have the ability with this kit to set the shift feel characteristics to one of two stages of shifting performance to best suite your particular driving style, heavy duty or street/strip.
The heavy duty, or Stage 1, setup provides noticeably firm shifts while maintaining driver comfort when compared to the stock shift feel for improved performance. Street/strip level, or Stage 2, generates slightly quicker and more aggressive shifts compared to the heavy duty level for high performance street and competition use. Stage 2 is the level best suited for the driver who is looking for the hardest, quickest shifts possible out of their 4R70W automatic transmission.
- Fluid Separators
- Drill Bits
As a basic understanding of what the Shift Improver Kit actually is, let's dig into a little general information about the 4R70W automatic transmission. The 4R70W is controlled by the PCM (Powertrain Control Module) which has complete control of its operation. Every single parameter that controls fluid pressure, shift point RPM and TCC (Torque Converter Clutch) lockup speed has been preprogrammed into the PCM at the factory. B&M created this kit as an easy way to bypass the less desirable features of the factory set shifts.
The B&M Shift Improver Kit mechanically recalibrates the 4R70W transmission to produce clean, precise shifts which helps to reduce clutch pack heat transfer and improve durability. This kit does not change or modify the shift point speed in any range. All shift points will remain under control of the PCM as they are currently calibrated.
Often times, upgrading the engine on your Mustang also means that you have to upgrade other components to be able to handle the extra power. One of the components most frequently requiring an upgrade is the transmission parts, and one of the leaders in providing those parts is B&M Racing & Performance.
