j-d. I have a 1999 (98 chassis) with the tow option on my shift lever. Was this an option on the 4R100 tranny.
PS sorry for bogart Ing the thread?
I'm not j-d, but my class C is on a 98 chassis.
I think if you look you'll find that the button isn't a tow/haul mode button, but rather an overdrive off button, and so labeled. It does exactly what it says, locking out the top (overdrive) gear. Tow/haul on the newer 5-speeds is a good bit more sophisticated, altering the shift logic in various ways, and in fact does not lock out overdrive.
