Providing you don't launch it, then you are safe with the standard items (as long as the car hasn't had a hard life prior to your ownership ).

The weak link is the MT75 3rd gear, once you get to 380+lb ft, it can strip the teeth off this gear just in acceleration.

At this stage, I would leave it alone, but start putting money aside for a brand new Ford 'box (just over £500). However, if you intend on hiking the power, then this is what I have on my own car (450bhp) - prices are on my website.
