I have a 1993 Honda Accord with a strange transmission problem. I can start the car and shift into drive and the transmission will run through the gears perfectly. after about 2 or 3 miles, the transmission will have problems shifting and will then just quit working at all. If I shut the car off and wait 5 minutes, restart the car, the transmission will work perfectly again for a little while. Any ideas?

It's the "shift" solenoid on your transmission has gone bad. Get it at the junk yard for around $80.00. You want the "shift" solenoid, not the "lock-up" one.You can see it on the front of your transaxle. It has a small electrical plug attached and comes off easily. Both solenoids may be together, or you may only have one. Easy fix, but depending on the doner car, your shift points may change (engine may seem racier)

First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,

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.

Theres a transmission cooling sensor and somtimes the wire comes loose from other repairs being done around it. or its just out. its on the left side sitting on the tranny. THATS WHY your d4 light is blinking

the first common possibilty would be to check fluid level, if the fluid level is good, I would recommend changing the transaxle fluid and filter. if this does not correct the issue, a professional transmission repair person will need to diagnose for you, good luck!
