The Performabuilt AODE, 4R70W Performance Transmissions


These Two Transmissions have been consolidated into this page since from A technical stand point they are similar in design and performance upgrades.

We are confident that these are the best performing FORD transmissions you will find anywhere!

  1. WE START WITH THE CORE. Our cores are chosen and only the latest model and cleanest cores for each of these units are Used. We then disassemble each units and carefully inspect all the hard parts for excessive wear and damage discarding any part that is not at specification, We then have every part cleaned in our high pressure cleaning system, The casing is then removed rinsed and heated so a hi temp specialty paint can be applied providing a hard and durable finish that wont easily peal off. The case is now reinspected for cracks and warpage to insure all sealing surfaces are true.
  2. NEXT THE PLANETARIES, BEARINGS, WASHERS AND BUSHINGS. These parts are carefully inspected and replaced as required, The planets are machined to improve lubrication, increase cooling and overall durability.
  3. NEXT IS THE 3-4 CLUTCH SET & DRUM. As we begin the assembly of the unit we first replace the sealing rings on the output shaft for the direct clutch with super sealing one piece rings, replacing the scarf cut and improving the sealing and pressure available to this clutch drum. In addition we replace the seals in this drum with high temp heavy duty seals and carefully assemble the piston into this drum. We then install the 8 alto redline frictions and Colene steels into this drum increasing its holding capability by 35 percent over its stock counterpart.
  4. THE MANUAL LOW AND REVERSE BAND is now installed. The new low servo piston is installed, band clearance and apply checked for proper operation.
  5. THE PLANETARY SET is again inspected and a roller sprag installed its function and clearances checked and proper hold of the sprag assembly checked very carefully as this sprag (Roller clutch)must with stand the full power of your vehicle at all times making this a critical area.
  6. THE CENTER SUPPORT is now inspected for warp damage and installed into the case with the heavy anti clunk spring and snap ring to keep it in place and avoid impact damage to the case.
  7. THE SUNGEAR AND SHELL are installed the sungear has been machined to provide additional lube and cooling to the planet The sunshell is the late type allowing the use of the late drum in the AOD to accommodate the wide band. The backlash is then checked to make sure its within specification.
  8. THE FORWARD (REAR DRIVE CLUTCH) is now inspected along with the pressed input shaft for damage and the seals are replaced. New heavy duty frictions and steels are installed and we do not remove the waved cushion plate from this drum as some others do causing a slam into gear from park or neutralunnecessarily placing stress on the gear train
  9. THE REVERSE INPUT (FORTH GEAR BAND) apply drum is then inspected resealed and new frictions and steels installed. For this drum we only use the late style 4R70W drum with the nearly indestructible Mechanical diode sprag assembly along with a swirl type retaining ring to prevent high rpm spin off and sprags explosion on performance second gear shifts.
  10. THE BAND AND OVERDRIVE SERVO these are two normally weak area in the AODE AND 4R70W units. We replace the servo assembly with a new heavy duty ford peice and we then upgrade the band to the Alto performance 4th gears band.
  11. HEAVY DUTY INTERMEDIATE (SECOND CLUTCH) frictions and steels are then installed and clearance checked with the pump installed and selective steels used to set the clearance for maximum apply.
  12. THE PUMP which is the heart of any automatic is then carefully inspected bushings gears and sealing rings are replaced as needed. All wearable and rubber parts are replaced.Gear clearance is checked to assure max volume and pressure and the pump is then finally installed.
  13. THE VALVE BODY is carefully inspected and our own specially re-engineered shift kit is installed. This shift kit provides performance shifts while retaining some of its manors for normal driving. In the kit, we also improve such issues as lube and lockup with the AODE and 4R70W, This kit will provided firm shifts at lighter throttles to neck snapping when at WOT.
