I added some to my 2nd hand auto box conversion (ZF4HP22). Can't comment yet as I've not driven it since the conversion but the reviews are positive: Amazon product and David Ashcroft recommends it: https://www.ashcroft-transmissions.co.uk/lubegard-instant-shudder-fixx.html
Can't do any harm but won't fix a knackered box.
edit - typing Dr Tranny into my browser brought up some interesting links.....

Used it a few times on a few different types of transmission, including my current FL1's Jatco box. It does indeed stop the shuddering caused by a TC clutch approaching the end of its life. Obviously the only proper cure is to replace the TC, but Dr Tranny Shudder Fix does keep a worn TC going engagement smooth for a good time longer.
Ive used it twice both on the smae D3 and it has worked well, first time about 3 yrs ago, fresh oil and Dr tranny cured the very slight judders straight away, second time the other week as the judders came back much worse this time, so fresh fluid and 2 tubes of DT and whilst its not perfect its made an 80 percent imprevement and I can live with that for the cheap cost.
Also helps if you can reset the gearbox adaptations as then the whole thing has to relearn and really does make for a nicer drive.
