Honda Civic 1999 Automatic Transmission

Resolved Question:

I have Honda civic 1999 and I believe it has 4 step gear (no.1,2,3,4)in the automatic transmission.

The transmission cannot run good. If the engine is cold, the transmission works good, but after awhile (especially when a lot of stop and run, like in the city road)it works not good.
The transmission cannot shift to Upper gear (no.4) and stuck in gear no.3 (it cannot move to upper and lower gear). So, the RPM car engine will be high in the freeway and move very slow when car just start, couse it start from gear no.3 instead of gear no.1.
So... what I did is move manualy the shift transmission from 'D4'(upper gear) to 'D2'(lower gear)If the car just start to move. And then I change the gear from 'D2' to 'D3' to get higher gear (its like manual shifting), then I change to 'D4' ,but most of the time the transmission gear can not move to 'D4' eventhought the hand shifting is already in 'D4' possition.

The check engine light is "on" and when I check with computer (The brand is snap-on, on the manual book says it works for honda civic 1999). The computer says " shiffting error".
Then I change the Shift solenoid Transmission, lower (on transmission housing)and reset the computer (turn off he check engine light). For the 1st and 2nd days it worked good but in 3rd day, it going back to the same problem and the check engine is on again !!!!

Could you help me what is the real problem...???
note: I used the used part (not brand new part)

Thanks for your help...

What is the actual code. Honda has a tsb for codes P0730 and P0715. I will wait to hear from you as to what the code is.
Customer: replied 8 years ago.
I don't remember what the actual code was, but I remember the meaning of the code , it said "Shift control error". It could be P0730 or P0715 (but I don't know).
