RARAYC 4L60E Shallow Transmission Oil Pan & TF289 Filter Kit — 16-Bolt, Felt Media Filtration

The RARAYC TF289 is a shallow 4L60E transmission oil pan and integrated filter kit designed to replace factory shallow pans with a pre-aligned filter head and felt media filtration for improved debris capture.

This kit is engineered for 4L60E transmissions that use a shallow pan configuration (16-bolt pattern). It combines a low-profile stamped pan with a molded gasket and a felt filter element that traps fine metal particles without restricting flow—useful when swapping pans during routine service, rebuilding, or upgrading transmissions in vehicles that tow or see heavy duty use.

How do I know this fits my vehicle?

Check the bolt count and vehicle compatibility before ordering. The TF289 is made for shallow-style 4L60E pans with a 16-bolt pattern and fits many GM models across Buick, Cadillac, Chevy, GMC, Oldsmobile, Pontiac, Isuzu and Saab lineups listed below.

• Confirm your transmission pan has 16 mounting bolts.
• Common fits include Escalade (1999–2006), Express vans (1996–2014 ranges), Silverado/Silverado HD variants, Suburban models, Rainier, Roadmaster and select Fleetwood years.
• When in doubt, compare OEM part numbers TF289, FT1146A, 24236799, 24200796, 24229186, 25174487.

What filtration and flow performance does this kit provide?

The kit uses a felt media filter designed to capture small metal shavings and other debris while preserving transmission fluid flow. The design targets fine particulate removal without creating excessive pressure drop, supporting reliable lubrication under load.

• Felt media captures contaminants down to approximately 25 microns.
• Maintains fluid flow around 12.5 GPM for consistent hydraulic operation.
• Filter and pan combination reduces harmful debris recirculation in rebuilt or performance vehicles.

How difficult is installation and what tools do I need?

Installation is straightforward for anyone comfortable with basic vehicle maintenance. The filter head arrives pre-aligned and the compression-molded gasket seats easily, so most pan swaps take about 15 minutes with simple hand tools.

• Typical tools: ratchet, socket set, torque wrench, drain catch pan.
• Pre-aligned filter head minimizes trial-and-error positioning and speeds assembly.
• Gasket compression fit reduces risk of leaks when torqued to specification.

When should I choose this shallow pan over a deep pan?

Choose the TF289 shallow pan when your vehicle’s transmission is designed for a low-profile pan or when clearance under the vehicle is limited. Deep pans increase fluid capacity but may not fit all chassis or aftermarket crossmembers.

• Opt for shallow pan if your original pan is low-profile with 16 bolts.
• Deep pans are better for added fluid volume—only use if chassis clearance allows.
• Verify vehicle-specific fitment to avoid return or fit issues.

Who is this for: The RARAYC TF289 kit is aimed at mechanics, DIY enthusiasts, and performance builders working on 4L60E-equipped vehicles that require a shallow, 16-bolt replacement pan. It’s especially useful when rebuilding transmissions, installing shift kits, or servicing trucks and SUVs used for towing where reliable debris capture and easy installation are priorities.
