Elctronic controleled transmission not shifting
I have an 01 tacoma prerunner 3.4l automatic transmission with ect button. I have removed the factory cluster do to it not fitting in the stock location anymore do to roll cage. I have installed aftermarket gauges except for a speedometer since I'm going gps speedo. When I plug my scan gauge 2 in it reads speed. But it is still not shifting automatically. I can shift it 1-3 manually. I'm sure it's an electrical issue I'm over looking. I have all the factory plugs still behind the dash and been splicing in to the harness as needed to make gauges work. Any additional input would be awesome.
Thanks |
AFAIK the trans ecu gets it's speed signal from the speedo cluster. The transfer case sends signal to cluster and cluster to ECU. Try plugging in factory cluster temporarily.
