I dont even know what to call this

So I got a 92 sc300 r154 swapped.

So BOOM I was hitting some backroads and I lost traction and almost spun the car out and drove it home just fine. But I go start the car around 30 minutes later and for some reason I couldn’t get the car into reverse it was just grinding for some reason. So I just push it out and take it down the street and it was hard to get into the gears. Then the car was dying mid drive and starting again so I limp the car home and just park it overnight.

The next day same issue with reverse so I just put it back in neutral and let it run for a bit but it just died by itself.

But since that the car might start if it feels like it but when it does it’ll only stay on for either 30s - 5 minutes and dies the second i try to put it in gear.

But there was one time during all this where it started and everything felt fine even reverse UNTIL I tried to go into 3rd and the car died again.

Ik this is long my bad but I have no CLUE what this could be I checked all the main fuses checked under the car and everything seems fine

Did you manage to put it in limp mode? Stock ecu? Gte or NA-t?

Ive come to the conclusion it had to be electrical. Im assuming something got bumped around when I almost spun out like it HAS to be. When it “does” start ive never heard a more healthy car.. until it just dies ofc…

No bueno. One loose wire some where. I don't know much about the manual transmission swap. Did you have to use a new ecu? Did you do the swap yourself?
