E-cowlboy Master Bushing Driver Set for GM 700R4/4L60 (13 pc) — CNC Steel, Black-Anodized

A complete 13-piece bushing, bearing and seal driver kit engineered to remove and install bushings on GM 700R4 / 4L60 / 4L60E / 4L65E transmissions quickly and accurately.

This E-cowlboy T-0220-700R4 Master Bushing Driver Set is built to OEM dimensions and designed as a direct-fit alternative to common professional kits (Atec, Trans-Tool, K&K, OTC, Kent-Moore, SPX). The set includes twelve purpose-shaped drivers plus a heavy-duty handle, all CNC machined from solid steel and black-anodized for corrosion resistance. It organizes the most common driver diameters used across the 700-R4 family so technicians and DIYers can press bushings, bearings and seals without guessing or makeshift tooling.

Which transmission parts does this kit work on?

The kit covers the key bushing and shaft locations found in 700R4/4L60-series units, both front and rear positions where correct seating matters for fluid flow and durability. Drivers are numbered to match common service charts so you can select the right tool fast.

• Input sun gear (front & rear), reaction carrier shaft, reaction sun gear
• Reverse input clutch housing, extension housing, case and front pump body
• Multiple front pump cover stator shaft drivers for different spline sizes

How does each piece in the 13-piece set help during repairs?

Every driver in this set is shaped to distribute press force evenly and avoid distorting bores or shaft shoulders. The handle gives a precise seating force that prevents over-driving, and the black-anodized finish improves longevity under shop use.

• 12 drivers (#61–#71 plus #60) sized for specific transmission locations
• One driver handle for controlled, straight-line pressure when seating bushings
• CNC machined solid steel for concentricity and long life under repeated use

What makes this kit a reliable replacement for OEM specialty tools?

This set replicates the form and function of established OEM service tools while offering the same service scope at a value price. Tight tolerances and hard-anodized surfaces reduce wear and help maintain fitment accuracy over many jobs.

• Matches common OEM tool numbers and service applications for 700R4/4L60 family
• High-precision machining maintains alignment to prevent part damage
• Corrosion-resistant coating and durable steel construction extend tool life

How should I use and care for the driver set to maximize service life?

Use the driver that corresponds to the transmission location, apply even pressure with the handle or a press, and avoid hammer strikes that can distort tools. Clean, lightly oil and store the drivers to prevent surface rust and keep dimensions true.

• Select the driver by number and seat squarely on the bushing or seal before pressing
• Use a hydraulic press or hand driver handle for controlled installation and removal
• Wipe clean, apply light lubricant for storage, and keep in a dry case between uses

Who this is for: This tool set is intended for professional transmission shops, experienced home mechanics and restoration specialists working on GM 700R4 / 4L60 / 4L60E / 4L65E transmissions. If you perform bushing, bearing or seal replacements and need repeatable, OEM-like fitment without buying multiple specialty pieces, this kit supplies the most-used sizes and a durable handle to complete the job faster and with less risk of damage.
