I replaced the transmission conrtrol module wihtout disconnecting the battery did i ruin the new module

code p 0700 refers to transmission control module(TCM)--malfunction===causes ---wiring---TCM
check for loose / corroded wiring connections and or/ replace thet TCM

You most likely have a defective transmission my friend.

Replace motor mounts, probably worn out.

When the car was jump started, you may have caused a voltage surge that affected the on-board computer module; and/or the computer module for the transmission.

Another possibility, once you disconnected your battery, you may have disrupted the on-board memory codes- such as the transmission's adaptive settings- so you may have to bring the car to the dealer repair shop or a transmission shop. Even if you take it to a local auto repairman, make sure he/she is an ASE certified mechanic.

Remove the battery negative cable for 5 minutes to reset the body control module and see if that corrects the problem. This can be a coincidence you know.

The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components.
• The automatic transmission shift lock control solenoid
• The brake switch
• The rear integration module (RIM)
• The transmission control module (TCM) or powertrain control module (PCM)
With the ignition ON, battery positive voltage is supplied to the automatic transmission shift lock control solenoid from the ignition 3 relay. The automatic transmission shift lock control solenoid is controlled by the rear integration module. When the rear integration module (RIM) receives a class 2 serial data message from the transmission control module (TCM) or powertrain control module (PCM) indicating that the shift lever is in the PARK position the rear integration module (RIM) grounds the automatic transmission shift lock control solenoid control circuit. This causes the solenoid to energize mechanically locking the shift lever in the PARK position. When the driver presses the brake pedal the rear integration module receives the brake applied signal and turns off the ground to the automatic transmission shift lock control solenoid control circuit. This allows the shift lever to be moved out of the PARK position.

Step
Action
Yes
No
1
Install a scan tool.
Does the scan tool power up?
YES - Go to Step 2
NO - Go to Scan Tool Does Not Communicate with Class 2 Device in Data Link Communications
2
Turn ON the ignition, with the engine OFF.
Attempt to establish communication with the Powertrain Control Module (PCM) and the Rear Integration Module (RIM).
Does the scan tool communicate with the PCM and the RIM?
YES - Go to Step 3
NO - Go to Scan Tool Does Not Communicate with Class 2 Device in Data Link Communications
3
Important: The engine may start during the following step. Turn OFF the engine as soon as you have observed the Crank power mode.
Access the Ignition Switch parameter in the rear integration module (RIM) inputs data display list.
Rotate the ignition switch through all positions while observing the ignition switch power mode parameter.
Does the ignition switch parameter reading match the ignition switch position for all switch positions?
YES - Go to Step 4
NO - Go to Power Mode Mismatch in Body Control System
4
Select the display DTCs function on the scan tool for the PCM and the RIM.
Does the scan tool display any DTCs for the PCM or the RIM?
YES - Go to Step 5
NO - Go to Symptoms - Automatic Transmission Shift Lock Control
5
Does the scan tool display any DTCs which begin with a "U"?
YES - Go to Diagnostic Trouble Code (DTC) List in Data Link Communications
NO - Go to Step 6
6
Does the scan tool display DTC B1000, B1004, B1007, or B1009?
YES - Go to Diagnostic Trouble Code (DTC) List in Body Control System
No - Go to Step 7
7
Does the scan tool display DTC B1327?
YES - Go to Diagnostic Trouble Code (DTC) List in Engine Electrical
NO - Go to Symptoms - Automatic Transmission Shift Lock Control

This is something best left to the Cadillac dealer !

On the transmission is the control module connected? From that point the connector on the transmission module follow it ,now is that harness junction connected(they should spit off) . If everything is connected with a scan tool they have to reset the index value,reset the tire do a transmission relearn and a battery quick disconnect. Before they can do all this you need to disconnect battery and put the terminal together, The old transmission adaptive strategy is still in the ECM,this is one of the challenges of voyagers rebuild and replace transmission Now you know why transmission shop dont want to do this work for voyagers

check modulator valve on transmission. check vacum to module,,that is probably it, if you need to reset system after replacement,, disconnect positive cable from battery for 5mins @ then try again,, hope this helps!!!!

The 1999-2003 Lexus RX300 models have a common failure of the engine computer that causes the harsh shifting of the transmission. You need to get the computer (ECM - Engine Control Module) rebuilt or replaced before it causes permanent damage to the transmission. Even if the transmission is already ruined, the ECM will still need to be repaired. Most often, the transmission is fine though, and rebuilding the ECM will restore the smooth shifts that the Lexus should have. Circuit Board Medics can rebuild the ECM and reprogram it so that you only have to plug it back in when you get it back. See the link below:

Does the 4 hi light blink when you try to put it in 4 wheel drive? My did that and it was the module.
