I'll be 53 this summer and I've only owned two automatics in my life. I really like my '06 Dakota but I find myself driving the transmission rather than the truck. What really bugs me is making a slow turn, then giving it a little gas and have it shift into overdrive at 30mph. I just don't like pressing the gas pedal and having the rpm's go down instead of up! I've tried driving it in tow mode but it's too severe (even when towing!). I understand that the 535rfe has it's own computer controller, called a TCM in the FSM. I did a little research and see that JetChips makes something called an "Accu-Speed" device. They mainly talk about speed correction for different tire sizes but also casually mention "corrected shift points" but don't provide any detail. Anyone have experience with the Accu-Speed or any other transmisssion controller?

 

I got the superchips tuner and love the difference it has made in the shifting and performance upgrade.

 

Did you get the flashpaq or the cortex tuner?
Thanks!

 

the flashpaq i have is worth the money just to play with the shift point, running nitrous i need to hold them a little longer and around town it works great

 

Got the flashpaq also!

 

sorry to high jack this thread but why does these truck only rev to like 4 k before it cuts out,is there anyway to rev past this without a tuner,does all of them do it or just mine,

 

If you're talking about revving in park or neutral I believe that's done to protect the engine. Take her out on a nice empty road and stomp on it, you'll see her go way past 4k

 

Not sure if the OP has the V6 or V8, but in my 6 I notice the same thing. I'd be interested to know if there's anything out there to help out the issue on the 6's.

 

in the OP signature, he says he has a 4.7

 

Coming from a Ford F150 with the 5.4 and the F250 Automatic 5 spd in it, this dakota shifts really really early and light. If i stepped on it in my old pickup you'd swear I nearly broke it loose on shifts.

I think i'll be getting one of those shift paks once my warranty is up... or before.

But yeah, is it just the programming? Cruising around town i have to REALLY stomp on it to go above 4k. Maybe i'm just not used to dodge tranny's?
