REBUILT TRANS. KIT 98-99 DODGE 4WD

Product Description

BD Performance Transmission Stage 4 Kit – 98-99 Dodge 47RE 4wd

The stock drivetrain was designed to handle the output of the stock engine, but not much more. BD Performance transmissions use revised oil circuits, extra clutches and stronger parts to handle up to 300% more power and torque than the stock transmission. All BD Performance transmissions come with a heavy duty transmission pan. Most Dodge and Ford transmission kits come bundled with their auxiliary Full Flow Transmission Filter kit for added protection and cooling! Not warranted for Race or Sled Pull use.

OEM transmission helical gears and engine torque thrust causes stock plastic and Babbitt thrust washers to fail. The contaminated oil and damages solenoids and valves. BD removes the thrust washers and installs roller bearings throughout the transmission which reduces oil contamination, maintains tolerances, reduces heat, and prevents premature solenoid failure.

Overview:

• All new bushings
• New design valve body
• Thrust washers replaced with roller bearings- saves governor solenoids and reduces friction
• Drilled intermediate shaft for increased lube
• Modified manual valve for lube in all positions
• 47RE transmissions upgraded with more rugged 48RE components
• Clutch Count: OD 6, OD DIRECT 10
• New input shafts and hub
• Pan adds 1qt extra oil capacity
• Up to 80% higher clutch apply pressures over the stock unit
• Pressure increase starts at lower engine RPM and at lighter throttle pedal position movement
• Light throttle shift firmness is also maintained
• No shuttle shifting problems
• Upgraded governor pressure transducer (47RE/48RE) and governor solenoid
• Cooler line case saver in every transmission
• Added heavy-duty clutches with up to 25% more material than stock
• Machined forward (rear) beveled pressure plate and overdrive brake (front & rear) pressure plate
• Direct clutch (front) piston machined
• High temp/energy Raybestos band
• Billet band strut, anchor, and dual ring accumulator piston
• BD auxiliary full flow filter kit for extra protection
• Clutch Count: FORWARD 5, DIRECT 5
• Fully rollerized geartrain
• Revised oil circuits
• Handles up to 300% more power and torque than the stock transmission
• Extra clutches and stronger internals
• BD aluminum heavy duty trans pan reduces case flex and fins keep temperature down
• Not warranted for Race or Sled Pull use
• Each transmission is dyno tested
