Pacific Performance Engineering PPE Premium Spin-On Transmission Filter 128059150 for Allison 1000/2000 Series — Double-Deep 15‑Mi

PPE Premium High-Efficiency Double-Deep spin-on transmission fluid filter 128059150 for Allison 1000/2000 series delivers finer 15-micron filtration and over 2.7× more media surface area than stock shorty filters.

Many factory spin-on transmission filters are compact and prioritize size over filtration efficiency. Pacific Performance Engineering (PPE) designed this double-deep replacement to address the common limitations of standard "shorty" filters used with Allison 1000 and 2000 series transmissions. By increasing media area and tightening particle capture size, the PPE filter improves fluid cleanliness, supports consistent fluid flow, and helps maintain the internal environment of the transmission under heavy use.

How does this PPE filter improve filtration compared to a stock shorty filter?

The PPE double-deep design contains approximately 2.72 times more filter media surface than the typical factory shorty, which spreads fluid across more area for lower restriction and greater dirt-holding capacity. It captures particulates down to roughly 15 microns, about half the size the standard spin-on typically removes. Better filtration reduces abrasive contaminants contacting clutch packs and valves.

• 2.72× more media surface area for extended service life
• 15-micron media captures finer particles
• Reduced restriction maintains steady hydraulic flow

Will installing this filter affect transmission shift quality or performance?

Improved filtration and consistent flow help keep hydraulic passages and valves cleaner, which can translate to smoother and more predictable shifts over time. The PPE filter is engineered to match OEM fitment and flow characteristics so it functions without introducing flow-related drivability issues. It aims to protect component life rather than alter calibration or shift timing.

• Cleaner fluid reduces wear on clutch plates and servos
• Designed for equivalent flow to OEM spin-on filters
• Supports more consistent shift feel under load

Is this PPE filter compatible with my vehicle that has an Allison 1000 or 2000 series transmission?

This spin-on filter 128059150 is built for use with many 2001–2019 Allison 1000 and 2000 series transmissions that accept a spin-on filter. It is offered as a high-efficiency replacement for common GM/OEM part numbers such as 29539579 and 12471607. Confirm compatibility by cross-referencing your transmission model and OEM part number before purchase.

• Compatible with select Allison 1000/2000 series transmissions (2001–2019)
• Cross-references OEM P/Ns 29539579 and 12471607
• Check vehicle/transmission fitment before installation

Who is this for? The PPE Premium High-Efficiency Double-Deep spin-on filter is aimed at owners and operators who rely on Allison 1000/2000 transmissions in trucks, tow rigs, fleet vehicles, and heavy-duty applications where longevity and consistent performance matter. If you want improved particulate removal, reduced risk of hydraulic contamination, and a filter designed to hold more debris without restricting flow, this filter is a practical upgrade to the compact OEM shorty option.

Features include a 15-micron filtration rating, improved fluid flow and filtering, over 2.5 times more filter surface area, and a design that promotes smoother, more responsive shifts. Install as part of routine service intervals to help protect internal transmission components and maintain dependable operation in demanding driving or towing conditions.
