Description
4L80E / 4L85E / TH400 Case Bushing, Sonnax 34006-SP.
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 4L80E 4L85E Case Bushing 34006-SP is specially designed to keep the bushing in the case bore.
Benefits:
- 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.
The housing bore should not measure more than 2.1285″ in diameter for an ideal fit.

- Material: Bronze
