A604, 40TE, 41TE

Symptoms:

• Planetary failure
• Shaft breakage
• Bushing failure
• Bushing wear

Cause:
Inadequate tolerance of OE bushings allows vital lube oil to exhaust.

Correction:
Renew critical clearances and restore normal operation by installing Sonnax overdrive clutch hub bushing.

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.
