WIT WHATEVER IT TAKES TRANSMISSION PARTS 4L60E 12-Piece Bushing Kit (1994 & Up) — Teflon & Bronze Durable OEM-Fit

WIT WHATEVER IT TAKES TRANSMISSION PARTS, INC 74030E is a complete 12-piece bushing kit engineered to replace worn bushings in 4L60E transmissions (1994 and up) for professional rebuilds and overhauls.

This kit gathers the most commonly replaced bushings for a 4L60E rebuild into one set, including Teflon-coated pump and extension housing bushings, bronze case bushings, and a full selection of stator, drum, shaft, and sun gear bushings. Components are sized to OEM-fit locations and made for durability during heavy use and repeated service intervals. The kit is intended as replacement hardware during a transmission overhaul when worn bores, shafts, or pumps are being reconditioned.

What does the 12-piece kit include and why each part matters?

The kit bundles the bushings technicians most often replace during a 4L60E rebuild to restore clearance, reduce wear, and improve fluid control. Each item targets specific rotating or oscillating interfaces inside the transmission to reduce metal-to-metal contact and preserve shaft alignment.

• Front Stator Bushing — supports stator rotation and alignment.
• Teflon Coated Extension Housing Bushing — reduces friction at the tailshaft area.
• Rear Direct Drum Bushing — restores drum bore tolerances.
• Teflon Coated Pump Bushing — enhances pump longevity and fluid sealing.
• Narrow & Wide Rear Stator Bushings — replace both stator bore sizes for proper fit.
• Front Reverse Drum & Sun Gear Bushings — ensure reliable gear engagement.
• Front & Rear Reaction Shaft Bushings — stabilize reaction shafts under load.
• Rear Sun Gear Bushing — keeps sun gear concentric with the planet set.
• Bronze Case Bushing — heavy-duty wear surface for high-stress areas.

How do the Teflon-coated and bronze bushings improve rebuild results?

Teflon-coated bushings reduce friction where fluid film may be thin and help hold lubricant at the contact surface, which can lower startup wear and promote smoother operation. Bronze case bushings add a robust bearing surface in high-load bores, resisting galling and extending service life compared with softer materials.

• Teflon coating improves lubrication retention and initial break-in behavior.
• Bronze construction increases wear resistance in critical case bores.
• Combination reduces fretting and axial play in rotating assemblies.
• Materials are selected for professional repair and repeated service cycles.

Will this kit fit my transmission and what applications is it for?

The 74030E is designed for the 4L60E transmission series from 1994 onward and covers the common bushing locations used in standard service and performance rebuilds. It is not a universal kit—verify compatibility with your vehicle's transmission variant and year before purchase.

• Compatible with 4L60E transmissions, model years 1994 and up.
• Suitable for OEM-style rebuilds, performance builds, and shop overhauls.
• Includes parts typically replaced during full tear-down and reseal jobs.
• Recommended for transmissions showing wear, shaft play, or pump issues.

How should technicians use these bushings during a rebuild?

Install bushings using the correct driver tools and press-fit techniques to avoid distortion. Confirm bore dimensions and shaft tolerances, apply appropriate lubricant during assembly, and follow the vehicle manufacturer's clearances and break-in recommendations.

• Use a hydraulic press or proper bush driver to seat bushings squarely.
• Measure bores and shafts to ensure correct interference fits.
• Apply assembly lube where specified; torque fasteners to spec.
• Replace related seals, bearings, and wear items during overhaul.

Who is this for? The WIT WHATEVER IT TAKES 74030E 12-piece bushing kit is aimed at professional transmission builders, independent repair shops, and experienced DIY mechanics who perform 4L60E overhauls or performance upgrades. If you need a consolidated set of durable replacement bushings—featuring Teflon-coated pieces for low-friction areas and bronze case bushings for heavy-duty wear surfaces—this kit provides the parts commonly required to restore fit and function to a 1994-up 4L60E transmission.
