8HP45 845TE Transmission Master Rebuild Kit BMW Jeep Dodge

This is a complete master rebuild kit for the ZF 8HP45 eight-speed longitudinal automatic, the transmission Chrysler badges in its 845 series (845RE/845TE) and BMW runs across most of its 2010-2016 rear-drive lineup. The kit bundles the clutch friction plates, the steel plates, the full overhaul gasket and seal set, and the rubber O-rings and lip seals, so you can tear the unit down and reassemble it without chasing individual part numbers. It carries the Transpeed reference code T21800A.

Fitment is wide. On the BMW side it covers the 1, 2, 3, 4, 5, 6 and 7 Series along with X1, X3, X5, X6 and the Z4 roadster from roughly 2010 through 2016, plus the Audi Q7 3.6L (2010-2011) and Land Rover Discovery/LR3 3.7L (2010-2011). On the Chrysler-group side it fits the Dodge Charger and Durango 3.6L (2012-2016), Ram 1500 3.0/3.6L (2013-2016), Jeep Grand Cherokee 3.0/3.6L (2011-2016) and Wrangler (2012-2016), Chrysler 300 (2011), and the VW Amarok. Confirm your exact application against the ZF 8HP45 build before ordering.

On the bench this is the kit you open when an 8HP45 is coming apart for a clutch pack failure, a harsh or slipping shift, or a case that has been leaking. The frictions and steels rebuild the clutch packs, while the seal and gasket set restores the sealing at the case joints and bolt interfaces so the unit holds line pressure once it is back in the vehicle. Buy the hard parts and torque converter separately if the failure went past the clutches.
