I wish you were out here in Iowa, Dennis. I'd take you for a ride with my v-6 and it's JMod. I did that for Thomas, and now he's organized the Iowa JMod tour.
For about $100 and beer (traded for a little help from my friends), I get hard shifts and very little clutch wear. I put 20K miles on in a year. There was very little sludge on the magnet when I changed filter and fluid. In fact, people have kidded me for changing the Mercon V too soon and wanted it for their car.
My last day at the track, I got tire chirp shifting to second and third without forcing it.
Don't forget to put on a transmission cooler. Best investment outside of a JMod for your transmission.
The Parts Bin Special is DEAD! It is being parted out.
