Re: PO884 Plase look in here !!

From reading through the codes, descriptions and the diagnosis procedures it seems the code is set by the TCM, but it is not due to the TCM.
Basically it is saying that the trans control system lost power,then had it restored while the shifter was in drive, and the vehicle was going more than 20mph. The diagnosis chart recommends checking all the fused B+, fused ignition switch outputs, and ground circuits to the PCM for intermittent shorts to ground or opens. Is it stalling at all?

Re: PO884 Plase look in here !!

check the tcm wiring as far as you can. Trace it and look for ANY damage from rubbing etc. Clean all conections. Do the same at your pcm and main wiring harness on the drivers side

Re: PO884 Plase look in here !!

Is there a TCM relay in the power distribution center of the WK? Could be a bad relay.
