1998 legacy gt random dies

[loonytooned]

Hello all again.

I have a new problem that's started in my year 1998 twin turbo legacy auto.

Ok hear we go I replaced the auto trans with another one exactly the same what a mission it was as well. Since doing the change I've had a few issues not with the trans but with the old girl just cutting out hears a couple of things that's happened. 1 after 2 weeks i drove to the shops and came back checked fluids in trans while she was running and went to put car in reverse and all the dash lights just came on and it started beeping at me and then it died it done this a few times then came rite no more issues for a week until i took my boy to school and then on the way home pulled up at lights to a stop and it just died on me after locking and unlocking the car and playing with the alarm immobiliser i managed to get it started and of I went its done it a couple of times.

Have checked all the wiring plugs etc and i am stumped. She has a turbo timer and uniden alarm immobiliser could any of these be the issue or something else.

thanks in advance for any help

Could be an immobiliser or turbo timer problem.

Does it idle normally, could be a sticky ICV (idle control valve) that needs a clean out. Also check your battery terminals are clean and tight. Check the electrical connections at the starter motor too.
