A conventional lock-up solenoid having a long delivery tube and mounting bracket with outwardly extending mounting legs is mounted on a transmission torque converter case requiring a lock-up solenoid with a short delivery sleeve. This is accomplished by a spacer member constituted by a pair of spacers carried on threaded studs which are received in the tapped holes. In effect, the spacer shortens the long delivery tube so that it fits the space of a short delivery tube lock-up solenoid. If the transmission is one requiring a long delivery tube, it is installed without the spacer and as any other replacement lock-up solenoid.
