2007 4R75E valve body rebuild

[88grandmarq]

rebuilt this valve body for a 2007 transmission. The engine is NA but has a few bolts ons. Since its wasn't a daily driver, the customer requested a very firm shift.

The pressure regulator valve was moderately worn, it was replaced with a new valve from Sonnax.

The end plug on the 2-3/1-2 shift valves usually wears and causes a pressure leak, a new plug with an o-ring is installed to prevent pressure leaks and sloppy 1-2/2-3 shifts
