Here tiddlywiki.com documents in Transclusion in WikiText
the use of parameters along side a transclusion of a template eg;
{{MyTiddler||TemplateTitle|Parameter|SecondParameter}}
You can use the \parameters pragma to access these parameters in the template
It also documents using a template in a “filtered transclusion” eg
{{{ [tag[mechanism]]||TemplateTitle }}}
However it becomes evident that the parameters feature is not available eg
``{{{ [tag[mechanism]]||TemplateTitle|First Parameter|SecondParameter }}}`
