If you check your error codes or have the codes read by a parts store, you
will probably find p0700 and p01776 and maybe one more.
The most common issue for the 02+ cars is not the input/output speed sensors;
it is an issue with the valve body and/or solenoid switch pack (or block).
You can order the rebuilt valve body from one of the online mopar dealers
(like mopar-wholesale.com). Cost is running close to $500 and they are
on back order.
I ran into these codes a month ago on my 2002 3.5L ES with 70k miles.
I pulled a valve body from a 91k mile 2001 SE at the local pic-a-part ($55).
I am in the process of rebuilding it. Really it's just a matter of cleaning
it out. I am adding a few new parts suggested by Sonnax. Sonnax
re-engineered a couple of the valve body internal parts so, I purcheased
those and will install.
After re-assembly, I will put the '01 valve body and SP (solenoid pack) into
the 2002 Trep, fill it with ATF +4 and keep my fingers crossed.
