Transmission Trouble PLEASE READ

sorry people. but im completly at a loss here, ive searched high and low for awnsers and i still cant find them, it all started a few weeks ago and the problems still here, ive takin it to the dealer and they want 500$ just to look at it and go through some wirinig, so if any of you can please help me it would be the coolest thing, cause i honeslty dont know what to do next, MY PRoblem, CODE P0700: Transmission Control System Malfunction, ( Dealer dosnt know what this means, said they would have to do a deep inpsection of wiring and testing, but jsut to do that they wanted 500$ not even to fix it. This code isnt the thing buggin me it what the code does to my car that bugs me, it puts my car in to LIMP MODE which i cant leave second gear, ive replaced shift solenoid block, input speed sensor and output speed sensors, all in hope to fix the problem, but its still there and for no logical reason i can see, If any of you have had the same or similar probel or can give me ideas of what it ould be that would be great. like i said i am completly stuck. It may be a simple fix or something way over my head, but any idea or awnsers would be greatly apreciated,. im tired of driving in second gear all day long. thanks ahead of time

ok just for shits and gigles i searched the code and yeah i got transaxle control system.. so bascially thats the same and proves we have the right problem for code. now what to do about it.. im not sure
only thing i can think of off the top of my head is did you reset the ecu after intalling the parts you put in? like take the terminal off the battery for a few minutes? im guessing you did but if not i know it wont clear out a check engine light unless you do and maybe with the code its stuck in limp mode until you do that.. other than that im stumped.. gl with it peace

normally when you get a limp mode problem, it's a malfunction TCU. i would say your TCU is probably fried. but just to make sure. go to www.dsmtuners.com /transmission/A/T forum and ask the guys there. they'll be able to comfirm if it's a bad TCU.

yea ive took the terminal off many of times. no luck there, but it might be a bad TCU that is what im thinking also.... do you know where i can buy one, i cant find any on ebay? thanks for your help guys
