What's the warranty on the TCM and the transmission? 1 year/24km ? Is it transferable.
Personally, I'd flog it private sale thru Kijji come this April. You really don't know what kind of POS they installed. It will be the cheapest, lowest quality reman that Mazda was able to source. In addition, if it fails you will be right back into that TCM bullsh*t.
