ECU/TCM Problems, Reset?

ive been having problems with my transmission lately, today i bought the parts i thought it needed and installed them, beliving this was the fix for the problem, after installation my car still goes back into "limp home mode" & Check Engine lite comes on, just as before i installed the new parts, i put a new input and output speed sensor in, and also installed a new solenoid block, because my ecu was reporting "shift solenoid C " malfunction. The thing is my car works fine for about 45 seconds always after start-up, then jumps back in to limp mode. The Question i am asking is, did i install something that was already fine to begin with and just didnt fix the problem, or Do i Need to go to the Dealer and Have the OBD-II COdes erased, i took the battery off maney times for long amount of time for reset, and it still does it, im not familiar with how ecu's hold memory and if it needs to be cleared/reset via obd-II reader or is battery disconnet just as well. please help if you have anythign to add or say, everyone thanks in advance.

i think its time for a manual trannie swap, you will never have that problem agian j/k. what are the codes it throws?

P0700 Transmission Control System Malfunction
P0733 Gear 3 Incorrect ratio
P0760 Shift Solenoid C Malfunction
...... i already replaced the solenoids, input/ouptut sensors, whats next?

when i threw a o2 sensor code and my check engine light came on in my 96 gs unhooking the battery cleared it from the ecu fine when i got that working right.. so im guessing its something else.. im not sure what it could be though..

P0700 is ur Pulse Genorator sensor it makes ur car stay in second gear and the computer go into limp mode its a speed sensor there r three of them on ur tanny cant think of all the names but i had same problem at 1 point
