Thankfully it is a six speed transmission. It has some death rattle going on if you let it sit for a couple/few days and surges during initial cold start.

That was only an issue on the older Chrysler based engines. So as long as it appears to be undamaged and in good shape, I would put it back in service. Unless it happens to be reasonably cheap, then I might consider it. On those engines, if the horrible rattle was caught soon enough, replacing the timing chain tensioner took care of it. If it went long enough, we had a couple where the chain wore through things from being slack, If I recall the timing case, causing an oil leak. But with them that loose, they had a habit of killing the engine, skip timing and lunch the valves, shear cam sprockets off, all kinds of carnage. Quick way to tell if the chain was slack was give the gas a fast rev and after the engine begins to drop rpm coasting back to idle they would start making a racket. Lot of issues with the turbo & induction system of the Cooper S. Trouble averted there! Same with the trans, glad its a real transmission, the car of the 3-pedal variety
