SOLD
For those that don't know these are "upgraded" shift solenoids that will firm and quicken shifts (recommended for real quick SRT shifts). There are a lot of threads on the subject over on the MB and Charger forums if you'd like to do more reading.
The ones I have were installed in my car for around 1k miles (before installing I did a trans flush and then changed the filter so the ATF was clean)...
these are part #'s 240 277 00 89
New these range anywhere from $200 - $300 a piece...
