The Forward clutches are locked together. Transmission was low on fluid at one point or release spring is broken.

P0736 Reverse Incorrect Gear Ratio OBD-II Trouble Code Technical Description Article by Dan Weller ASE Certified Master Technician Reverse Incorrect Gear Ratio This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. What does that mean? Modern vehicles equipped with automatic transmissions / transaxles use a torque converter between the engine and transmission to increase the engine torque output and drive the rear wheels. This code can show up in vehicles with an automatic transmission when there is a problem shifting into reverse gear, or while driving in reverse. The automatic transmission changes the output direction to move the vehicle in reverse and is most often controlled manually through hydraulic pressure even on computer controlled transmissions. The Engine Control Module (ECM), Powertrain Control Module (PCM) or Transmission Control Module (TCM) uses input from various sensors to verify the correct operation of the transmission and its components. Engine speed is often calculated against the transmission speed sensor to determine gear ratio and torque converter slip. If the calculation does not match the desired value, the Diagnostic Trouble Code is set and the Check Engine Lamp is illuminated. Incorrect ratio codes typically require an advanced mechanical ability and diagnostic tools. Note: This code is similar to P0730, P0730, P0731, P0732, P0733, P0734 and P0735. If there are other transmission codes, repair those problems first before proceeding with an incorrect gear ratio code. Symptoms Symptoms of a P0736 trouble code may include: Check Engine Light illuminated (Malfunction indicator lamp) Delayed shift or not shifting into reverse gear Transmission slipping Potential Causes Causes of this DTC may include: Low or dirty transmission fluid Mechanical failure inside transmission Internal blockage inside transmission main control Faulty Shift solenoid Faulty transmission control module Diagnostic/Repair Steps Always be sure to check fluid level and condition before proceeding with further diagnosis. Improper fluid level or dirty fluid can may cause shifting issues that affect multiple gears. If only one incorrect ratio code is being displayed, test drive the vehicle to determine if the gear is actually working. The transmission internal clutches and bands are usually controlled by a solenoid or using fluid pressure. If there is an electrical issue with a shift solenoid, a code specific to that fault should also be displayed. Correct the electrical issue before proceeding further. Blocked fluid passage inside the transmission can also cause the vehicle to not shift into reverse gear, if there are multiple incorrect ratio codes but the transmission performs as expected, there could be a mechanical issue with the torque converter, transmission main control, or pressure problems. If there are multiple incorrect ratio codes and shift issues, but not all are displayed the fault may be a mechanical issue internal to the transmission, or a fluid pressure / blocked passage in the main control. A shift solenoid that controls multiple gears can also be at fault if there is an internal blockage or fluid pressure problem. If there is an electrical problem with the solenoid that controls the gears, a code should be displayed specific to the solenoid at fault. Reverse gear in the transmission is typically not controlled by a solenoid, it is fully hydraulic. If the transmission will not shift into reverse gear, there is most likely a mechanical or pressure problem causing the issue. It may be necessary to use an advanced diagnostics scan tool to determine which gear is being commanded by the transmission, and to determine if the engine speed matches with the calculated output speed from the transmission sensor. Advanced knowledge of transmission operation and overhaul is often required to repair this type of malfunction. Consult the factory service manual for vehicle specific diagnostic procedures.

Both error codes you have are transmission related. P0736 is an error for reverse has wrong gear ratio. P0700 is a general transmission problem code

Not good if it makes a grinding noise. Needs a tech or replacement as something most likely has come loose inside the transmission.

"Where do I find the pressure switch circuit: LR"


There is a row of plugs beaneath the solenoid pack. One of those is a rev pressure port. If reverse is gone, I am betting on a broken internal part.
