Intermediate stub shaft failure is a common problem in Ford AODE, 4R70W, 4R70E and 4R75W, 4R75E transmissions used in abusive applications or with increased power levels. Sonnax heavy duty intermediate stub shaft 76670A-01 is specially heat-treated, cryogenically processed and shot-peened for maximum strength and resistance to fracture, making it the strongest drop-in option for AODE/4R70W units.

• Manufactured from 300M ultra-high-strength steel
• Shot peened to prevent micro-cracking
• Rolled splines for increased strength and durability
