Default Blinking Sport Light on 91 Accord SE

Ok let me give my history with this problem first its a 1991 Honda Accord SE. When i first got this car i had to change the transmission and i did then was when i saw the "S" light blinking but after a few when the used transmission broke in and blend with the engine all was well. I then noticed that when it rained then the "S" gives the blinking problem and when its dry it works fine (i figure now that then the TCU box was getting wet). Last year around this same time my car was in a flood that damaged the car ECU & TCU my mechanic tried getting them repaired but they were badly damaged i guess so he replaced them with something that will work. After i got it back from him the "S" light keeps blinking all the time and my first gear for the car is so lazy when i come to a stop u hear the engine revving high but the car barely move. When the car reaches second gear it works. Off and on it had spells when the car did work fine in first gear had the power and everything from a fresh start but once i make a stop like to the gas station or a store it goes back to its lazy ways. I also did a road run of the car and also found out that my last gear or over drive gear wasn't working i can only get like 95mph out of the car when it is at floorboard. At first when it was working fine before the flood i could not floor the car because i was doing like 110mph which was a safe spot speed for me so i didn't not go any faster. Alright let me get to the recent stuff now. Recently they broke in my car stole my radio and battery and so happened the night after we experienced flooding again and my car got flood again because i couldn't move it. Today i went and took out my ECU & TCU to check for water damage the ECU did no get wet at all but the TCU did so i dried it out and everything and as soon as my car is back to normal i put them back in. Now onto my findings and questions finally. When i too out my ECU and checked the model which is "31820-PT3-A54" and verify it on the net it says its for a 92-93 accord not a 91. The correct 1 for my 91 should be "37820PT3A03" so i was wondering if this will cause any problems with anything? Next the TCU or "AT CONTROL UNIT" in my car when checked the model number which is "28100-P0H-A01" when i check that on the net it says its for a 94-95 accord and not for my 91. So my question is could this be the problem why my "S" light keeps blinking. Next i would like to also know if anyone knows what is the correct model for my TCU for my 91 accord SE sedan and if u know where i can get a used one thanks.
