Location: Sun Prairie, WI | Like wavridr said on gm products it doesn't stop the trans from going into over drive. It does increase the line pressure in the tranny and raise the shift rpm. With the higher pressure you will notice it hits the gears harder thus less slipping of the clutches during the shift preventing clutch wear. I use mine only when getting onto and staying on a highway. I dont like the way it shifts in town with it on. I have to go 40mph before it will shift into 3rd gear
As far as Dodges go all I know is that my 97 ram and 2000 durango just had an overdrive off button. I always left it in OD unless I noticed it shifting alot then I took it out. Better fuel milage that way and your engine isnt turning at 3000 rpm going down the highway.
The new gm tow haul mode is awsome. It actually down shifts when slowing down and acts as an engine break. |
