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. If you need a different transmission tool or variation, message us before ordering. INMN products are independently manufactured and designed for users who require functional, reliable tools. This tool is produced by INMN and is not associated with any original equipment manufacturers.

  • Fits: 46RH / 46RE / 47RH / 47RE / 48RE Dodge transmissions. Purpose: Holds OD spline alignment during overdrive unit service. Saves time: Less fighting the OD unit during reinstall. Material: INMN-made, 3D printed PETG (won’t rust). Included: (1) tool. Ref: 6227-2 / 6227A-2 (verify need).
