Newly Rebuilt 4L60E 4WD Transmission & Transfer Case

This freshly rebuilt GM 4L60E 4-speed automatic transmission paired with a compatible 4WD transfer case (such as NP241 or similar) is a robust, electronically controlled unit ideal for street, towing, and light off-road use. Stock versions handle approximately 350-360 lb-ft of torque and engines up to ~400 HP, with a maximum shift speed around 6,000 RPM. A quality performance rebuild—featuring upgraded 3-4 clutch packs (7-9 plates), hardened input shaft, reinforced sun shell, 5-pinion planetaries, high-performance servos, and valve body upgrades—boosts capacity to 450-600+ HP and 450-550+ lb-ft reliably.
Key specs include gear ratios of 3.059 (1st), 1.625 (2nd), 1.00 (3rd), and 0.696 overdrive (4th) for strong launches and efficient highway cruising with lower RPMs. The aluminum case keeps weight around 150-175 lbs wet, and proper maintenance (fluid/filter changes every 30k-50k miles) supports 150,000+ miles of durability in rebuilt form.

Durability shines with upgrades addressing common weak points (3-4 clutches, input shaft, sun shell), making it far more reliable than stock for modified applications. The 4WD setup excels in trucks and SUVs for traction in varied conditions.

Best project cars include LS-swapped classics like Chevy Camaro/Firebird (F-body), C10 trucks, El Camino, Jeep conversions (with adapters), Silverado/Sierra builds, or Tahoe/Suburban restomods. Its compact size, overdrive, and affordability make it a popular choice for budget-friendly performance and 4WD swaps.
