I have run continuity check on all wires between trans and ecu and they are all good. I've checked for corrosion on the speed sensors and respective plugs. I have also been under the impression that ECM's rarely go bad. What is the consensus on maybe a faulty torque converter since I reused the old one?

Nope, no secondary codes.

Well, I replaced the transmission and the P1730 code remains and still no overdrive. I am at a loss. Do I throw more money at it by buying an ECM?

Anyone have an ECM/ECU they can let me borrow?:) I did notice today that it won't go into O/D which is still not definitive on the problem being the transmission or the computer.

It is from the Diagnostic manual

Hello everybody! I'd like to see if anyone else has any ideas. My 2000 fwd RX300 (145K) has a P1730 code. It drives and shifts fine and I've tested both speed sensors and they are within normal limits and so is the wiring to the ECM. I know the next logical step is to replace the ECM to see if that is the problem but can't see spending a $100 bucks just to see if that is the problem. I know these have a history of transmission problems but don't the sensors just read the teeth going by? Any ideas or suggestions would be appreciated. thanks.

Do you have Nav or an entertainment system? It could be an over-ride so it can function without the vehicle at a stop....just a thought.
