2000 Volvo S70 Front Wheel Drive Automatic 137, 00 miles
I have a 2000 S70 GLT with over 100,000 miles on it. I had the transmission rebuild about two years ago at a Volvo dealer.
Over the past few months the check engine light has been illuminating occasionally with a variety of transmission codes:
-P1618-Fault in lead between AW 50-52 and Monotronic 4.3 (MIL Requested)
-P0740-Torque Converter Clutch Solenoic Circuit
The engine and ttransmission have been running fine throughout this period.
It is time for the vehicle's inspection and now the codes cannot be cleared. It seems to me that I may have a problem with the transmission computer module. I was thinking about sourcing a used computer to replace the existing unit.
Does anyone know whether a used computer will work in this application? I am concerned about the cost if I take it into a dealer. Money is very tight for me right now.
Is there an estimate for the cost of brand new transmission computer and reprograming?
