TH700-R4, 4L60

May not work in some late-production sun gears with OE finish-in-place bushings.

Symptoms:

• Bushing failure
• Reaction carrier shaft damage

Cause:
Oil leakage due to inadequate support of the reaction sun gear.

Correction:
The Sonnax sun gear bushing is more than one-and-a-half times as wide as the OEM and maximizes bushing support.

Warning:
Measure the sun gear bore. Installing this bushing into a bore that is smaller than 1.705”-1.706” will result in a tight fit with the mating reaction shaft.

The Sonnax wide reaction sun gear bushing is one-and-a-half times the width of the OE version and fills the entire sun gear bushing groove. This wider bushing maximizes support. The bushing is steel-backed bronze that is precision machined to provide minimal clearance with the mating shaft.

• Provides better control of lube oil
• Has more support for sun gear and reaction shell
• Greater longevity than OE bushing
• 1.5 Times wider than OE for maximum support

Specifications:

• Material: Steel-backed bronze
• Bushing Style: Precision
• Housing Bore: 1.706"
• Shaft Dia.: 1.575"
• Width: 0.600"
