Quoted From DrivewayAl:
I believe that is the trans. and it has 77,000mi. The trans fluid and filter have been changed twice since I had it since 28,000mi. Thanks for the tip, I am going to take to my friends garage tonight so he can scan for trans. codes. So you think this is more trans. related rather than engine or electrical?

It could be since you have no CEL light on.
Use only ATF +4 in an A604 transmission anything else will cause it to have a short life. I’ve had mine replaced 3 times. Now I do a complete flush every 50,000 miles and in between about 25,000 after complete flush I drop the pan, install new filter and clean debris from magnet. Never had any engine problems with my 1990 3.3 (280,000 miles on it) just trans problems and regular replacement service (brakes, pads, shoes , rotors oil changes, etc).
