the 42LE is a 606 which comes in the intrepids,and concordes.
to the OP, what is the problem your having with the trans to need to test the solenoid block? the pre-2000 cars with the 606 used to have wiring harness problems, while as beyond 2000, it seems the biggest problem with the 606 (42LE) or the rear wheel drive version which is the 42RLE is either speed sensor related issues, or a P1776 DTC.
the deal with the P1776 DTC is rather simple, if the date code on the solenoid block is listed from 3001 (the 300th day of 2001) to 0603 (the 60th day of 2003), the problem is in the solenoid block. if it is not in the range given, the problem is in the valve body and a new valve body will need to be obtained.
