Shift Kit AODE, 4R70W
SHIFT KIT (AODE/4R70W) 1991-ON
- Just one Superior kit does both the AOD-E and the 4R70W Transmissions
- The AOD-E kit offers regular and heavy-duty applications
- Use of this transmission in police cars many times means come backs due to unit failure. This package was largely designed and developed through field testing on police vehicles
- Included in this kit is a special design Spiral “Plus” ring set. The “New Millenium” two piece design in the AOD-E Shift Correction Package features the Spiral Ring and the G-lock ring, teamed up to withstand testing at over 16,000 RPM on a dynamometer. Even at that high speed the new design did not fail. The New Spiral “Plus” ring set replaces the stock snap ring that often times slings off.
