6227-2 Overdrive Spline Alignment Tool for 46RH 46RE 47RH 47RE 48RE – OD Planetary & Sprag/Overrunning Clutch Alignment Aid, PETG

Designed by INMN, this overdrive spline alignment tool is engineered for service work on Dodge automatic transmissions that use the 46RH / 46RE / 47RH / 47RE / 48RE overdrive assembly. It helps maintain spline alignment of the overdrive components during handling and assembly so the unit can be positioned and reinstalled more smoothly. This is a shop-friendly aid for transmission rebuild work where repeatable alignment and reduced rework matters. The tool is manufactured from high-strength PETG material, selected for its balance of rigidity and controlled flexibility. This construction supports consistent dimensional accuracy and a smooth, non-marring fit compared to metal tools. PETG also resists typical shop conditions and will not rust, making it suitable for repeated use. ADDITIVE MANUFACTURED PETG CONSTRUCTION – Produced using an additive manufacturing process with durable PETG material for consistent dimensions. This INMN tool is intended for overdrive section service steps where the planetary/overdrive gear train and overrunning (sprag) clutch hub need to remain indexed to prevent spline “clocking” out of alignment. It provides a simple way to hold alignment while the overdrive unit is moved, positioned, or prepared for reinstall. Common reference numbers for this style include 6227-2 (also commonly seen as 6227A-2 depending on catalog naming). Always verify your transmission model and the required service tool reference before ordering to ensure correct fitment. What you get: (1) overdrive spline alignment tool as pictured.
