- Same Spec, Smarter Spend – This Ortopia automatic transmission filter is built to the same hydraulic and filtration specification as OE 29537966. Designed exclusively for the Allison 1000 5-speed and 6-speed automatic transmissions with DEEP oil pan—4WD trucks, dually (DRW) configurations, and heavy-duty applications. Features an extended pickup tube with anti-slosh design. No downgraded materials, no shortcuts. You pay for the engineering, not the dealership markup.
- Problem & Solution – Addresses delayed forward engagement, harsh 2-3 upshift, transmission overheating under load, and P0700/P0730 codes—all traced to restricted fluid flow from a clogged filter. The Allison 1000 depends on high-volume fluid flow for cooling and hydraulic pressure; a saturated filter starves the pump under heavy throttle, causing slip and elevated transmission temperatures. This filter restores proper fluid flow, eliminating shift flare and overheating often misdiagnosed as a failing torque converter.
- Allison 1000 Deep Pan Only – Direct-fit for Allison 1000 5-speed and 6-speed automatic transmissions with DEEP oil pan (approximately 4" pickup neck depth). Compatible with 2001-2010 Silverado 2500 HD 4WD, 2007-2016 Silverado 3500 HD 4WD, 2001-2010 Sierra 2500 HD 4WD, 2007-2010 Sierra 3500 HD 4WD, and 2006 H1 Alpha. Features extended tube and anti-slosh design. Critical: DEEP PAN ONLY—not for 2WD shallow pan configurations.
- Buyer's Checklist – Confirm your Allison 1000 has a DEEP oil pan—approximately 4" pickup neck depth. Check your drive type: 4WD and dually (DRW) models typically use the deep pan. Engine codes covered: LB7 (2001-2004), LLY (2004-2006), LBZ (2006-2007), LMM (2007-2010), and early LML (2011-2016) in 3500 HD applications. Warning: 2WD models with shallow pan need a different filter (29537965 or 29542833). Measure your pan depth before ordering.
- Installation Workflow – ① Lift vehicle, drain fluid via pan drain plug, remove pan bolts criss-cross. ② Drop deep pan carefully—Allison holds significant fluid; use a large drain pan. Clean pan magnet thoroughly. ③ Remove old filter by unbolting and pulling down from valve body. Compare old filter pickup tube length—must match the 4" deep pan profile. ④ Install Ortopia filter, torque bolts to 89 in-lbs (10 Nm); ensure extended tube fully seats. ⑤ Clean rail, install supplied gasket, torque pan bolts criss-cross to 89 in-lbs. ⑥ Refill with approved Allison TES 295 ATF, check hot level. No reflash required.
