SPEED SENSOR & TCU MODULE BAD????1997 Rs

Hey guys, need some help here.... I just got a 1997 eclipse in great condition I thought. Two weeks after I got it, I had to take it to the shop cause it was stock in like 2nd gear after about 30min in the highway. It did run fine in the city but just not in the highway. Anyways, the guy told me it's was in "Limp mode" and the speed sensor needed to be replaced among with some "leaks". Unfortunally, that was $700. It's been 3 weeks and the problem came back two nights ago, took it to the same place and they just called me saying I need a Tcu Trans module. That I can only get that from the Mitsubishi dealership and it will run$400.. plus all their little extras is gonna be another $700. Don't have that type of $$$ to be handing out... and don't know to much about cars, so just need some advice for what or if this makes since to you experts!!

Thank God for Junk yards.... I had to take care of these problem myself, can't trust anyone it seems like now days.. Anyways, I got a TCM and installed it myself...I'M SO PROUD OF THAT! The car seems to have more power but the check engine is still on. I don't know if I need to get it restart or reprogram or something. Do you guys by any chance know what I can do. Thanks

Hey, I just got your email, and responded to it. Glad to see you got it fixed. As far as getting the light to go off, I covered that in the email too.
