The Engine Control Module (ECM) uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical troubles of the shift solenoid valves and valve body.

couple of things to try first , is the trans fluid at correct level ? when was the fluid last replaced ? have the OBD codes read as may tell you what the problem is , if you done all this i'd go to a repar shop for advice

code p 700 refers to transmission control system/mil---malfunction===causes ---wiring --- TCM ( transmission control module)
code p 0730 refers to incorrect gear ratio====causes --TR sensor / switch--shift solenoids---transmission mechanical fault
code p 1740 refers to torque converter clutch solenoid
it is probably correct that dealers will not remove and repair transmissions but I suspect that they are not as reputable as they could be because the codes indicated are repairable in car
I am thinking that there is no mechanical problem requiring a $4,500 transmission so I suggest that you take it to an accredited professional transmission shop and get a proper diagnosis and a quote to replace the faulty tcm and TR sensors

im no expert on trannies but it sounds like synchros. That code is shift malfunction, which im sure you already know. Id also check the shift cable.

Code p0740 is a problem in lock up control solenoid assembly, Check whether scan tool indicates another code. Does the scan tool indicate another code? YES - Perform the Troubleshooting Flowchart for the indicated Code(s). Do not continue with this troubleshooting until the causes of any other DTCs have been corrected. Measure the line pressure. Is the line pressure within the service limit? Repair the hydraulic system as necessary. Replace the Lock-up Control Solenoid Assembly set lock-up control solenoid valve/shift control solenoid valve A assembly and the A/T clutch pressure control solenoid valve A/B assembly. Turn the ignition switch OFF, and reset the PCM memory by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds . Using the scan tool, check to be sure that the engine coolant temperature is 176°F (80°C) or above . Drive the vehicle at 55 mph (88 km/h) for more than one minute . Recheck for code P0740. Does the OBD II scan tool indicate code P0740? YES - Remove the torque converter and inspect for a missing torque converter O-ring. If the O-ring is damaged or missing, replace the transmission and torque converter. NO - The system is OK at this time.

Change the fluid. Since you only get about half of the fluid to drain during a change (the rest is held in the torque converter with no way to drain it), you will have to change the fluid three times in order to dilute the "dirty" fluid with enough clean fluid to make the end product mostly clean. Change the fluid, then run the car for awhile. Repeat two more times. And only use Honda fluid.
