Sonnax 42LE Transmission Overdrive Clutch Hub Bushing 92004-SP Fits early-style hubs with shaft O.D. of 1.142" and housing bore of .959". OE overdrive clutch hub bushings in 41TE and 42LE units often leak critical lube oil due to imprecise clearances with the underdrive shaft. This loss of lube oil regularly leads to planetary damage and shaft breakage. The two-piece OE bushing design allows excess radial movement of the shaft, hastening failure. Installing improved, one-piece Sonnax overdrive clutch hub bushing 92004-SP restores the crucial clearances necessary for optimal performance. For late-style hubs with shaft O.D. of 1.162" AND housing bore of .937" Sonnax offers overdrive clutch hub bushing 92004-L. For late-style hubs with shaft O.D. of 1.162" AND housing bore of .941" Sonnax offers overdrive clutch hub bushing 92004-LOS.
