3 speed tranny?

I was wondering if anyone has this type of tranny? My gear shift shows: P,R,N, Dw/ circle 2,1. I thought the EX were supposed to have four spped w/OD! Is it just only me that has that or does anyone else has it too? I have a 2001 EX 6.8L V10 non diesel. 42,000 miles on it. I bought this from a dealership with pressure from my wife to get a new vehicle. Can I swap the current 3-speed to a four speed tranny? Any suggestions would greatly be appreciated. Thank You!

The d with a circle is overdrive. There is not 3 on the selector because to be in third gear, you just push the overdrive off button (possibly tow/haul) and overdrive is deactivated. So that tranny is a four speed.

Wierd huh! Well I guess that eases my mind! Thanks for the info!

If you ever count the actual sift points there are 5.
