TransGo 46-PLT-96 4L60E Valve Body Separator Plate (1996-2006)

The separator plate is the thin steel plate sandwiched between the valve body and the case, and every feed hole and orifice in it meters the fluid that runs your shifts. When you tear a 4L60E down, that plate is often worn, blued from heat, or wallowed out around the check-ball seats, and reusing it is how you end up with soft shifts, cross-leaks, and a rebuild that never feels right no matter how good the rest of the parts are. This is the correct replacement plate for the 1996 through 2006 4L60E, cut to the factory hole pattern so pressures land where they should.

It is the plate TransGo specs to run with their reprogramming and shift-correction packages on this transmission, so if you are installing a shift kit or building the unit for towing and heavier duty, starting with a fresh, correctly-orificed plate means the calibration work actually does what it is supposed to. Bolt it up with new valve body gaskets on both sides and you have a clean, square sealing surface instead of a warped one fighting you the whole build.

Fits the 1996-2006 GM 4L60E behind small blocks in Silverados, Sierras, Tahoes, Suburbans, Camaros, and the rest of the rear-drive lineup. Confirm your unit's year, since the 4L60E hole pattern changed across the run. A cheap part to buy fresh, and an expensive one to skip.
