TH400 & 4L80E Case Bushing
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.
Note
The housing bore should not measure more than 2.1285″ in diameter for an ideal fit.
