When buying a "complete transmission", if it's not complete with cross-member, nut's, bolts, washers, oil-lines and donut etc sufficient for your requirement,
haggle the price down hard.
Pay attention to these little things, because you could easily end up paying more for nuts & bolts than you did for the transmission!
These 'insignificant' ( "Easy fix mate" ) components are difficult to source used and new ones add up to arms and legs.
For reference, here's a list of all these little bits & pieces, with part no.s and prices too when they come my way.
The waaaaay out of date Toyodiy $ prices are there to give you a clue.
Should you have information of any recent prices in £ GBP, please don't be too complacent to let me know and I can then update the price & credit.
Thank you.
