Car runs perfect then code appeared parked it then it shut off instantly. I replaced the igniter already

 

The usual issue with the igniter code seems to be old brittle wiring and connectors going through the valley to the coils. Sometimes it's a loose connection do to broken a connector(s), wires that have cracked and are able to touch each other or the engine, corrosion or fluid from leaks entering wiring/connectors. Many possibilities as these engine's are aging. But the P0715 code is bad news for the transmission I'm afraid. I'd have a real diagnosis done from a transmission specialist shop, otherwise throw an input shaft speed sensor at it and hope for the best. My experience is that you will need a new trans with that code.

 

Thanks bro, I got it fixed it was bad wire connection & cracked wire
