Sonnax GM TH400 Case Bushing 4L80E TH-400 4L80-E Automatic Transmission

Product Details


The OEM case bushing in vehicles with a THM 400 or 4L80-E transmission tends to walk-out of the housing bore. This allows the bushing to wander into the extension housing, leaves the output shaft unsupported, and may ruin the governor gear. The cause of this problem is the lack of a flange or stop surface on the case bushing to prevent the walk-out from occurring if the bushing begins spinning in the bore. The Sonnax case bushing 34006-SP is manufactured out of high quality bearing bronze and is specially designed to remain in the case bore. This bushing has a flange on the transmission case side that prevents it from pushing completely through the bore. In addition, the flange accurately locates and helps retain the selective washer. The machined oil grooves allow for a supply of lubricating oil to enter the extension housing, as well as the transmission case.
