E-cowlboy 700-R4 (4L60/4L60E/4L65E) Bushing Driver Set — 13-Piece CNC Steel Kit, Black Anodized

The E-cowlboy T-0220-700R4 Master Bushing Driver Set is a 13-piece, CNC-machined installer/remover kit designed to fit and service bushings, bearings and seals on GM 700-R4 (4L60, 4L60E, 4L65E) transmissions.

This complete driver set groups the common drivers needed when rebuilding or repairing 700-R4 family transmissions. Each driver is machined from solid steel, anodized for corrosion resistance, and sized to match specific locations inside the transmission case, pump and carrier so you can press bushings and bearings in or out cleanly without improvised tooling.

Which transmission locations are covered by this kit?

The kit includes thirteen pieces—drivers #60 through #71 plus a driver handle—each mapped to a precise transmission feature so you won’t have to guess which tool fits. That mapping covers the sun gears, stator shafts, reaction carrier, reverse input clutch housing, extension housing, case and front pump body.

• Driver #60: input sun gear (front & rear)
• Drivers #61, #67, #68, #71: front pump cover and stator shaft variations
• Driver #62, #69: reaction carrier shaft positions
• Driver #63: reaction sun gear
• Drivers #64, #65: reverse input clutch housing rear positions
• Driver #66: extension housing
• Driver #70: case fit

How does this set improve transmission servicing speed and accuracy?

Using the correct driver for each bushing location reduces the risk of misalignment, part damage, or uneven pressing that can occur with makeshift tools. The precise fit makes installs and removals faster, giving cleaner seating and repeatable results.

• OEM-sized drivers match factory bushing dimensions
• CNC machining yields concentric faces for even force transfer
• Single-handle system lets you drive multiple sizes with one tool

What materials and finishing choices ensure durability?

Each driver is manufactured from heavy-duty solid steel and finished with black anodizing to resist rust and wear in workshop environments. The hardness and surface treatment extend service life under repeated impact and press operations.

• Solid steel construction for strength
• Black anodized surface for corrosion and wear resistance
• High-precision CNC faces for longevity and repeatability

Is this kit compatible with other branded tools or OEM references?

The E-cowlboy set is designed to be a direct replacement for several established trans-tool kits and listed references, allowing technicians who previously used Atec, Trans-Tool, K&K, OTC, Kent-Moore or SPX-style tooling to switch without changing procedures.

• Replacement for Atec Trans-Tool and similar kits
• Matches references like T-0220, T-0220-700R4 and SKU311
• Works across 700R4 / 4L60 / 4L60E / 4L65E family transmissions

Who is this for? The E-cowlboy T-0220-700R4 Master Bushing Driver Set is intended for professional transmission technicians, independent shop owners and experienced DIY mechanics who rebuild or repair GM 700-R4 family transmissions and want dedicated, durable drivers that reduce installation time and protect internal components. Backed by a 12-month warranty and a 30-day satisfaction return policy, the kit offers a practical toolbox upgrade for anyone servicing these common GM automatic transmissions.
