well, cant get the dam pic to load but its essentially just the switch in the dash anyways
as for the review...my only complaint is that its not as effective as i would prefer it be, and heres why...
...when you are coming downgrade you have your foot completely off the gas correct? well, in these automatics that drops your RPM's to just over 1,000, and as you can read in the link, this mods effectivity is best over 2,000RPMS. does it still work below that? sure, just this weekend we came down from 7,300 feet and i noticed it would still drag our speed down to the 1500RPM range but was essentially useless below that.
NOW THEN, if there were a way to force the autos to downshift, this would be a top ten mod...otherwise, if you have a manual in your truck, and EVER plan on hooking anything to your hitch, this would be one of the first mods i would suggest doing
EDIT...now that i think about it more, my review has been based on curvy mountain 2 lane hiways, 30-50 MPH limits. if were talkin about 4 lane restricted access freeway speeds, just simply shutting off the Overdrive coming down will probably be FANTASTIC, but i wont be able to comment on that until we do our yearly cross-country pull in September
