The ZTech I-SHIFT Pressure Sensor Repair Kit (21068286) allows individual pressure sensor replacement within the Volvo I-SHIFT automated transmission without replacing the entire control unit. The I-SHIFT system uses multiple hydraulic pressure sensors to monitor and control automated gear engagement. A faulty sensor causes erratic shifting, I-SHIFT warning codes, and reduced transmission efficiency. This kit provides a cost-effective repair solution for Volvo VNL fleet operators.

Q: Which transmissions and trucks does this repair kit fit?
A: Fits Volvo VNL trucks equipped with the I-SHIFT automated manual transmission. Replaces sensor 21068286.

Q: What symptoms indicate a faulty I-SHIFT pressure sensor?
A: Erratic gear changes, I-SHIFT fault codes on the dashboard, hard shifts under load, or transmission refusing to engage specific gears.

Q: What is included in this repair kit?
A: Includes replacement pressure sensor(s) and seals needed for the repair — check product listing for exact kit contents.

Q: Is this cheaper than replacing the full transmission control unit?
A: Yes. Individual sensor replacement is significantly less expensive than a full TCU replacement and restores proper I-SHIFT function.

Q: Do I need to recalibrate the I-SHIFT after sensor replacement?
A: A basic I-SHIFT adaptation may be needed after sensor replacement — consult Volvo VCADS diagnostic software for the procedure.
