G4AEL Steel Plate Kit 18-Piece

The G4AEL Steel Plate Kit is an 18-piece transmission steel plate set used during rebuilding and overhaul of G4AEL automatic transmissions. The product shown contains multiple steel clutch plates with different diameters, spline profiles and tooth patterns, allowing the kit to service several internal clutch-pack positions within the transmission.

Steel plates work together with friction plates inside automatic transmission clutch packs. During operation, hydraulic pressure applies the clutch piston and compresses the friction and steel plates together. This creates the holding or driving force required to transfer torque through the transmission.

This product is intended for professional automatic transmission workshops, gearbox rebuilders, distributors and wholesalers. Because steel plate thickness, spline design and clutch-pack location can vary between transmission versions, customers should compare the original plates and transmission model before ordering.

G4AEL Steel Plate Kit Function

The G4AEL Steel Plate Kit provides the steel mating surfaces used alongside friction discs inside the transmission clutch packs. While friction plates contain friction material, steel plates are plain metal components that provide a rigid surface for clutch engagement.

When hydraulic pressure applies a clutch piston, friction plates and steel plates are pressed together. The resulting friction locks the clutch pack and transfers torque through a particular gear path.

Steel plates must remain flat and smooth. Heat, slipping, insufficient hydraulic pressure or worn friction material can cause overheating and discoloration. Severe clutch failure may also warp the steel plates or create scoring and surface damage.

Replacing damaged steel plates during rebuilding helps restore correct clutch-pack clearance and provides a clean mating surface for new friction discs.

18-Piece Steel Plate Configuration

The product shown is supplied as an 18-piece steel plate kit. Your photo clearly shows several groups of steel plates with different diameters and spline arrangements, which is normal because one transmission uses multiple clutch packs with different internal designs.

The kit should therefore be described as an 18-piece transmission steel plate set, not as 18 identical plates.

Before installation, technicians should compare each replacement plate with the original component. Important matching points include:

• Outside diameter
• Inside diameter
• Internal or external spline pattern
• Number and shape of tabs
• Plate thickness
• Clutch-pack location

If the original transmission has previously been rebuilt, physical comparison becomes especially important because mixed-generation or aftermarket parts may already be present.

Steel Plates and Friction Plates

Steel plates and friction plates are designed to work together as one clutch pack. When friction discs become worn or burnt, the neighboring steel plates may also be damaged by excessive heat.

For this reason, professional rebuilders normally inspect both components during transmission overhaul.

Steel plates should be checked for:

• Blue or dark heat discoloration
• Warping
• Scoring
• Cracks
• Distorted tabs
• Surface roughness
• Abnormal thickness variation

A visibly overheated steel plate should not normally be reused with new friction material. Damaged steels can reduce clutch performance and may contribute to repeated transmission failure.

G4AEL Transmission Rebuild Inspection

During a G4AEL rebuild, technicians should inspect the complete clutch system rather than replacing only one damaged plate.

Related components may include friction plates, clutch pistons, sealing rings, drums, return springs, bearings, bushings and valve-body components. If the transmission suffered clutch burn-up, the fluid and oil pan should also be checked for friction debris.

Hydraulic pressure problems should be corrected before new clutch components are installed. Low line pressure, valve-body leakage or damaged seals can cause a new friction and steel package to fail again.

The G4AEL Steel Plate Kit should be installed using correct clutch-pack clearance specifications and professional rebuilding procedures.

Clutch Pack Clearance and Installation

Correct clutch-pack clearance is important after steel plates and friction discs are replaced. Too little clearance can cause clutch drag, while excessive clearance can result in delayed clutch application or poor holding capacity.

Technicians should measure the assembled clutch pack according to the appropriate transmission specification.

Transmission fluid should be clean, and all related drums and hydraulic passages should be inspected before assembly. Steel plates should be installed in the correct order and orientation for each clutch pack.
