1. Introduction
This manual provides essential instructions for the proper use and application of the TCI 890900 Transmission Seal-Up Kit. This kit is designed to seal various openings on automatic transmissions, specifically Powerglide (PG), TH350, and TH400 models, during storage, transport, or rebuild processes. Proper use of these seals helps prevent contamination and fluid leakage.
2. Product Overview
The TCI 890900 Seal-Up Kit includes a variety of plastic plugs and caps in different sizes and shapes, typically colored orange and blue, to fit common transmission openings. These components are crucial for protecting internal transmission components from dust, debris, and moisture when the transmission is not installed in a vehicle.

3. Installation and Usage
Follow these general guidelines for installing the seal-up kit components:
- Identify Openings: Before installation, identify all open ports and shafts on the transmission that require sealing. Common openings include cooling line fittings, tail shaft, and the front pump area where the torque converter slides in.
- Select Correct Plug/Cap: Choose the appropriate size and shape of plug or cap from the kit that provides a snug fit for each opening. The kit includes various sizes to accommodate different transmission models (PG, TH350, TH400).
- Secure Fitment: Gently press or tap the chosen plug/cap into place. Ensure a tight seal to prevent contaminants from entering and fluids from leaking. For some plugs, a firm press may be required. Avoid excessive force that could damage the plug or the transmission opening.
- Verify Seal: After installation, visually inspect each plug and cap to confirm it is securely seated and provides an effective seal.
Note: While the kit provides plugs for many common openings, it may not include a specific cap for the torque converter shaft that slides into the transmission. Users should verify all necessary openings are sealed based on their specific transmission model.
4. Usage Considerations
- Temporary Use: These seals are intended for temporary protection during storage, transport, or while the transmission is out of the vehicle for service or rebuild. They are not designed for permanent installation or use in an operational transmission.
- Cleanliness: Ensure the transmission openings are clean and free of debris before installing the plugs to achieve the best seal.
- Material Compatibility: The plugs are made of plastic. Avoid exposing them to extreme heat or harsh chemicals that could degrade the material.
5. Maintenance
The TCI 890900 Seal-Up Kit components require minimal maintenance. Periodically inspect the installed plugs and caps for any signs of damage, cracking, or loosening, especially if the transmission is stored for an extended period or transported. Replace any damaged components to maintain an effective seal.
6. Troubleshooting
- Leaking: If a plug or cap is leaking, ensure it is the correct size for the opening and is fully seated. A loose fit or an incorrect size will not provide an adequate seal. Some users have reported minor drips from certain plugs; ensure the tightest possible fit.
- Difficulty Fitting: If a plug is difficult to fit, verify it is the correct size. Do not force plugs that are too large, as this can damage the transmission opening or the plug itself. If a plug seems too small, it will not seal effectively.
- Damaged Plugs: If a plug breaks during installation or removal, replace it with an undamaged component from the kit or a suitable alternative.
