I just bought a 92 Eclipse GS Turbo, with a bad TCU. The car is stuck in limp mode. I decided to see how bad the problem was. I took out the TCU and this is what I found.
I went to the junkyard and got another computer from a non turbo Laser DOHC, but it didn't work. I need MD750093. Is there any place I can get one cheap?
Aww man I checked the Part Numbers today and they are different. Im not even sure if this thing I have is the TCU...I thought it was? Here is a picture of what I have.
If the Car works in Limp mode, you may be able to make or buy one of those SHIFT boxes. Its an UP and DOWN button that you use to Manually Shift throught the gears. I had to do that in My Jeep cause the TCU is bad. So when I run through first I push a button and it powers up the 2nd gear soleniod and shifts me into second.
