Heavy Duty Case Bushing
Part No. 34006-SP

fits TH400 1965-on , 4L80E - 4L85E (all years)

The OE case bushing in vehicles with a GM TH400, 4L80-E and 4L85-E transmissions tends to walk out of the housing bore. This leaves the output shaft unsupported, ruins the governor gear and can cause case damage. The no-walk flange feature of the Sonnax case bushing 34006-SP is specially designed to keep the bushing in the case bore.

• High-quality bronze
• Flange on the transmission case side prevents bushing from walking completely through the bore
• Flange accurately locates and helps retain the selective washer
• Machined oil grooves allow for a supply of lubricating oil to enter the extension housing as well as the transmission case.
