I will work on getting a factory service manual. This needs to be address within the next 6 months. I want this to happen. I was thinking along the same lies as Wayne. I know the solenoids and sensors are located inside the transmission toward the bottom and basically are what controls the cars extra smooth gear shifts. If we could even wire it so the car thought it was in nuetral at all times it would be fine at which point i think the obly thing needed would be for the number one and two shift solenoids to be present. As for the toyota ecu I have searched 1000x over and can not find any kind of unit that can manipulate it to the point of permanently switching a code off. You can clear them but that is as far as it goes. I know GM and subaru have ROMs out there that can actually manipulate and turn off or remove codes and triggers. ---

I had retained this because it showed how to trouble shoot solenoids in the transmission and displayed some basic wiring diagrams [http://www.97supraturbo.com/Supra%20Scans/2JZ-GE%20Transmission%20Diagnostics.pdf](http://www.97supraturbo.com/Supra%20Scans/2JZ-GE%20Transmission%20Diagnostics.pdf) ---

> The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D > gear). The ECM then compares the actual gear with the shift schedule in the ECM memory to detect mechanical > trouble of the shift solenoid valves and valve body. That might be difficult to trick. It will throw a code if it’s not correct. ---

Feed it a constant “0mph” and tell it is in neutral. Just need to figure out what the speed sensor spits out for 0mph. ---

Ok I went through the pdf. 1. The shift solenoids can be replaced with a 15ohm resistor to prevent codes related to electrical issues with the solenoids. However the ECU will throw a mechanical error code based on the speed of the car and when it shifts. If it detects a certain speed and it hasn’t shifted yet it might throw a code. Maybe selecting manual mode and wiring the gear position sensor to a manual trans will work? It’s going to be tricky though. 2. The ATF temp sensor can probably be replaced with a 5kohm resistor. 3. You will need two speed sensors on the new trans. 4. The park/neutral sensor will trip if the car is moving over 44mph and/or a certain rpm ect. You might have to wire it so it thinks it’s in drive and if the ECU needs a start signal you’ll have to wire a switch or something. I need a better pinout of the ECU to determine more. 5. The bitch is the clutch lock-up, the ECU monitors the air flow sensor and throttle position to determine if the clutch is locking or not. I don’t see a easy way around that. The only option I see is to get a manual ECU. ---

Just need to figure out what the speed sensor spits out for 0mph. The speed sensor will be 0 pulses for 0mph. It will throw a code for speed sensor malfunction. But the pdf Ron linked doesn’t go into details about that. ---

Just need to figure out what the speed sensor spits out for 0mph. The ECM might throw a code if its reading 0mph from the spped sensor but knows it is indeed in motion. Also inorder to get 0mph from the speed sensor i believe then you would have to affect the speedometer as well as the tachometer correct? ---

You can probably jump the speedo wire from the sensor straight to the cluster.
