It is only my way of thinking but once the drive quality is compromised by a "failing" TC then it is too late for the gearbox and valve block assy
Transmission Oil in the sump is lifted through an oil filter by the pump and then fed to the TC
The TC then under pressure feeds the autobox
So ANY swarf originated by the TC is NOT filtered so therefore box is always unprotected from debris
Some warning of drive quality are :-
No drive from cold for a small amount of time until system pressurises
Smooth as silk gearchange becomes "no longer smooth as silk" !
Downchanges become noticeable - hard to describe but easy to notice if you drove vehilce for a while and this effect starts happening
Gearchange eventually becomes jerky
Total failure can end up with no drive forward or reverse or gearbox locks in 3rd and is an absolute pig to pull away under 3000 rpm !!!
Any of the above mean the dreaded swarf is already making its way through the gearbox !
Unfortunately, the metal used for the valve block is soft and wears so you might like to consider a valve block upgrade while it's in bits.
