    Hey guys, I've done some research here and am still not quite sure about this.

    My car is a 96 Eagle Talon 2.0 non-turbo with automatic transmission.

    The ECU i want to put in it came off a 97 Eclipse 2.0 non-turbo with manual transmission.

    So same car the only difference is the automatic vs manual transmissions.
    Can i put the manual transmission ecu into the automatic transmission car? thanks a lot guys.

    By the way. here are the posts i was looking at, both for 2gs, but one for turbo and the other for non turbo if you wanna check it out

    verify production dates to be 100% accurate, but most 97 and newer PCMs use a 2 plug 100 or so pin PCM. Where as most 95-96 if not all use a 1 plug (connector) 65 pin PCM.

    That would be your first issue. Secondly, a manual pcm will be missing the pin outs for the can system to your ATX pcm, with out these reference signal pins, you will have no ATX function. That is of course that you are still planning on using an ATX and have not already switched to an MTX.

    Further more on top of that, between early 96 and late 96 their are several provision p/n for ATX transmissions referring to federal or California emissions, and ect.

    Here is the possible chart/list for PCMs in relation to production date:

    The manuals have a different PCM vs the automatic as i believe...After i did a manual swap, it required a PCM from a manual car

    As black cotton stated, the 96 and 97 ecu's are different. Not only that there are differences in the auto and manual. It might be more inclined to work if you had the same years, but if you are going to spring for the same years, then you might as well grab the same transmission ecu type as well.

    I personally wouldn't read much into the turbo forums, its a completely different engine, only real things in common are the body styles

    hey thanks a lot guys. i appreciate your input.

    What do you think about this that i just found?

    http://members.shaw.ca/costall/1000Q/answers-ECU.htm#DoestheECUcontrolthetransmission

    I basically says that the ecu is separate from the transmission control unit, and they dont communicate, but only share some sensors.

    Its conflicting and thats why i want to see what you guys think. thanks guys.

    That FAQ was built to provide information to 4G63 owners; its information doesn't necessarily pertain to the 420A. The 420A TCU does have several direct connections to the ECU. In addition, the TCU interprets the signals from the input and output speed sensors and provides the ECU with one signal.
