I have recently had done a 2gr conversion into mr2.

Engine is out of an aurion which has a transmission control module (TCM) fitted to the standard gb, I am running a manual.

The code is U0101 lost communication with tcm.

I have done a little research, the ecu and tcm communicate via a can network which apparently is hard to bypass or trick the ecu into thinking
it is operating normally.
I did not get the tcm with the engine package.

So my options are to get another tcm and hope i can get it to happily communicate with the ecu or
get another non TCM ecu and have my self an unknown amount or re-wiring to do.
I know the standard kluger has no tcm and no imobilizer but has a 6 plug ecu, my current aurion one is a 2 plug.

I would much prefer to go with the tcm option if it would work so if any of the experts have any ideas it would be greatly appreciated.
