Learn how to use punctuation. I quote reading part way throught the run on sentence.

You are correct. An auto ecu is looking for signal of the car being in park. Then in your car it is going into limp mode because it thinks your trans is about to break.

There are ways around this but they are not for unknowledgable people.

For sure dont wanna try messing with the computer. I just have to find him a similar ecu to mine than. If i am correct p75=ls than a51 means=america,automatic,obd1 but both of our cars are standard. So would that mean i have the original 1.6 si automatic wiring harness and he has 1.5 automatic harness and therefore have to run an auto ecu? Thank you for all the advice would be lost without this forum and your help.

Yes, you both likely have stock harnesses in the chassis. one might have a jumper harness or the wiring was re-done to bypass lots of the things that each ecu was looking for.
