Code U10100, TCM lost connection?

I've replaced my TCM in my vehicle listed above, however I've been told that it was originally a manual. That's not how I brought it though. I've had it for 7 months the TCM in it originally was changed a year ago. The new TCM has cleared the U010100 code which showed warning lights of AT and traction control and engine light warnings. However, it has returned after changing the TCM. The car listed above is a sp25 and I've remounted the TCM on the firewall, so it doesn't get hot any other suggestions with only the U10100 code coming up that's all.
