I've got a 450c that would not build transmission pressure (20psi). After all adjustments and checking regulator, I pulled top cover off. Discovered​ the pressure line was broken. There was also an old braze repair on the low pressure line that had failed. Hoping I can fix both in machine and avoid a teardown. Just figured I'd pass my findings along since there seems to be many reasons these HLR'S lose pressure.
