Description
Allison 1000 T1 & T6 Bearing, Late Design | 2001-2019 — 29539501
This is the Allison late-design thrust bearing (part number 29539501, also sold through GM Genuine Parts) for the T1 and T6 positions in the Allison 1000 transmission behind the 6.6L Duramax. It measures 2.12 in outside diameter by 1.26 in inside diameter and is used in 2004 and newer Allison transmissions. Each transmission uses two, one at T1 and one at T6.
Thrust bearings carry the axial load between the rotating parts inside the Allison, and a failed bearing can lead to expensive planetary damage. A proper overhaul replaces all of the bearings. On 2001-2005 5-speed transmissions, measure the old T1 and T6 bearings before ordering, because these units can use either the late design or the early design. For a full rebuild, see the Allison 6 Speed Bearing Kit, LBZ, LMM, LML, L5P | 2006 - 2019 .
