Genuine OEM Spec Allison MD Speed Sensor – 29544139 – Non-Retarder, Heavy Duty Replacement

This here’s a brand new OEM spec speed sensor for Allison MD non-retarder transmissions.

Works with most heavy duty Allison units — direct fit, no fuss.

Now, quick heads-up: it doesn’t come in the original OEM box, just plain packaging, but the part itself is fresh and meets all OE specs.

Manufacturer part number is 29544139, so make sure that’s what you need before ordering.

Comes with a 1-year warranty too.

If your transmission’s acting up or throwing codes, swapping out the speed sensor is a solid first move.

Universal fitment?

Nope.

It’s made specifically for these Allison applications.

No core charge, no extra junk you don’t need.

Just a clean, direct replacement that gets the job done.
