If prior to removal the overdrive was disengaged during acceleration then the splines in the planet carrier and in the uni-directional clutch may remain torsionally loaded on the transmission mainshaft.

This condition will prevent the overdrive from being withdrawn from the mainshaft.

It may be possible to release the overdrive by applying 300-350psi oil pressure to the hydraulic test port and then the switching solenoid on and off but I've never needed to try this.
