Three – Sonnax TH400, 4L80E No “Walk Out” Case Bushings 34006-SP
3 Sonnax bushings for only $33.00
The OE case bushing in vehicles with a GM THM-400, 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 bronzeFlange on the transmission case side prevents bushing from walking completely through the boreFlange accurately locates and helps retain the selective washerMachined oil grooves allow for a supply of lubricating oil to enter the extension housing as well as the transmission case.
The housing bore should measure between 2.1285″/2.1295″ in diameter for an ideal fit. When damage to the case is so severe that bore diameter is larger than 2.129″, use Sonnax oversized case bushing 34006-OS. See instructions for details.
