M32 Gearbox Updated Endcase Shim Upper and Lower Mainshaft 24461955 1.35mm

Genuine M32 Gearbox Updated Endcase Shim – Upper and Lower Mainshaft 1.35 mm (24461955)

A genuine 1.35 mm mainshaft shim (part number 24461955) for the updated M32 Gen 2 endcase upgrade. This shim sets the correct mainshaft preload at positions 31 and 56 when fitting the upgraded endcasing. The required shim thickness is determined during the rebuild measurement process — not before.

Fits transmission: M32 Gen 2 (updated endcasing) — does NOT fit the first-generation M32 with the original smaller endcasing

OE part number: 24461955

Dimensions: 1.35 mm thickness

Material: Metal

Fitment location: Positions 31 and 56 on the M32 gearbox diagram (upper and lower mainshaft end-case shim positions)

Note: Shim thickness is determined during the gearbox rebuild measurement process and cannot be pre-selected. Please measure before ordering. This part should only be fitted by an experienced transmission technician.

Is this 1.35 mm shim a common size for M32 rebuilds?

The M32 shim measurement falls across a range of thicknesses depending on the individual gearbox's tolerances. The 1.35 mm is one of the sizes frequently required — but only a direct measurement during the rebuild will confirm whether this is the correct size for your application.

What tools do I need to measure the correct M32 shim thickness?

You will need a dial gauge (DTI) with magnetic base, the correct M32 endcase measuring tool, and a torque wrench calibrated to the required endcase bolt specification. The measurement procedure is documented in the M32 workshop manual.

Can an incorrect shim damage the M32 gearbox?

Yes — a shim that is too thick will create excessive bearing preload, leading to overheating and rapid bearing failure. A shim that is too thin will leave excessive endplay, causing noise, bearing fretting and eventual gear-change problems. Correct measurement is critical.

Does Eco Torque offer the full M32 endcase upgrade kit?

Yes — Eco Torque stocks the complete M32 updated endcase upgrade kit including the endcase housing, bearings, and shim assortment. Contact us if you need a full kit rather than individual shims.

How long does an M32 endcase upgrade take?

In a professional workshop, an M32 endcase upgrade typically takes 6–8 hours including removal, rebuild, shim measurement and refitting. It requires the gearbox to be removed from the vehicle.
