I was talking to a freind of mine the other day about gear spitter "underdrive/overdrive" he is a dodge guy and we were woundering why you never see them on any diesel that has been moded. Maybe dosent handle the extra HP and TQ??? To me it seems that have those extra gears would be kinda nice, I'm not planning on buying one just would like some info if anyone has some, any feed back or personel experiance on this would be great so if you do let me know.
they will work fine on a diesel but most people shy away from them because of the price. a gear vendors will run you 3,000.00 plus 5-700.00 to install.
With it installed how many more "gears" or shift do you have now?? I just started looking at them today and they really interset me, I guess I just have alot of questions about them, thanks for such quick replies.
So how exactly do you shift it with an auto? I have been trying to work that out for some time.
I would think it would go like this with an OD unit. The OD here refers to the aux tranny.
1st -1st OD- second - second OD - 3rd - 3rd OD - 4th - 4th OD.
But how does it know to go back and forth between all of those gears? Surely you cant keep up with it manually?
I agree, would be tough to shift with a tranny, but not impossible, I read one of their test runs on an OBS truck with E4OD, sounds like you just manually run through all the gears if you need them. This reminds me so much of the road ranger gears in our Cab over trucks used on the farm. Man I loved shifting those trucks!
Matt: So, it doest automatically give you 8 gears. In auto mode, it just goes into second OD.
cangim: It would be so nice to have an fully automatic 8 speed.
I have one on my Excursion PowerStroke and auto tranny and I just let it shift normally up to high gear, then I let off the pedal, push the switch, wait till it kicks in, then go again. This is easier than letting it shift itself b/c it doesn't jerk and puts less stress on then aux tranny.
