My car has a transmission code but shifts fine — is it a sensor?
Often yes. Speed-sensor and pressure-switch faults are frequently electrical. Send the codes first; we'll point you at the likely part before you authorise a teardown.
Do you supply internal wiring harnesses?
Yes — internal and external harnesses and conductor-plate gaskets for the major platforms.
Are oil pans supplied with gaskets?
Pans and gasket sets are both available; confirm against your transmission code.
How do I identify the right sensor?
By transmission code plus sensor location (input speed, output speed, pressure, gear position). A photo of the connector settles it in most cases.
