Transfer Case Brace

[coachgeo]

apparently, other Allison Tranny's with a Rear added T-Case have issues with breakage from vibrations. Though the one described below appears to break in different location from unintended vibrations than the 3070/3700 version in our trucks the result is the similar. Just throwing out there as an interesting tid bit! Not pointing out that this is a for sure weak point on our trucks; esp. if on does meticulous maintenance.

DescriptionCracked transmission tail shaft housings .... are a common problem for GM Allison-equipped 4x4 pick-ups in offroad and drag racing situations. Even a normal amount of driveline vibration can cause the housing to fail, resulting in a transmission fluid leak or worse; internal transmission and transfer case damage. Once the housing cracks, repairing it requires removal of the transmission and transfer case.

PPE’s new Transmission Transfer Case Brace helps support the overhanging, heavy transfer case by spreading the load up and across the adaptor housing to the center section of the transmission.

PPE’s Transmission Transfer Case Brace utilizes two 304 stainless-steel 7/8 inch support tubes tied together with a thick 304 stainless-steel plate for increased strength and service life.

Mounting the brace is a quick and easy job that can be done without removal of the transmission or transfer case. No special tools required.
