KM172 KM170 KM175 A4AF1 A4AF3 [79-UP] Automatic Transmission Front Band 171

A worn or cracked band in an A4AF1, KM170, or KM175 unit causes slipping during apply events, and replacing it with the correct piece stops that slippage without having to source a full rebuild kit. This listing covers one band, chosen for the specific servo bore and apply geometry of those three unit codes, so the technician is not adapting a band meant for a different family.

REMCO has been working in automatic transmission parts since 1991, and every piece that ships from here is pulled and checked against its item record before it leaves. This band is no exception: it is verified against the SKU before packing, and the box includes a part slip so the technician can confirm at the bench what arrived.

The band weighs 0.65 lb. There is nothing else in the box: no seals, no clutch packs, no Automatic Transmission Filter, no gasket set. If the rebuild requires those components they need to be sourced separately. Checking the full parts requirement before placing the order avoids a second shipment and a delayed job.

The single most important step before purchasing is confirming the transmission unit code. A4AF1, KM170, and KM175 are related units but not identical in every dimension, and this band is validated against all three. If the unit code on the case or in the vehicle service record does not match one of those three designations, this band is not the right piece for that job.

• One band covers the servo application on A4AF1, KM170, and KM175 automatic transmission units, addressing worn or broken band failures directly.
• This listing is a single band only. It does not include seals, clutch discs, steels, Automatic Transmission Filter, gaskets, or any other rebuild components. Review your parts list before purchasing.
• The band is selected specifically for the geometry and friction requirements of the A4AF1, KM170, and KM175 unit family, so fitment is not a guess.
• Contents: 1 transmission band. Item weight: 0.65 lb. No additional pieces are included in this shipment.
• Before ordering, confirm your transmission unit code is A4AF1, KM170, or KM175. A wrong unit code means a band that will not seat correctly.
