Man i sure would like to be able to lock out 4th gear on my 05. Is there a tsb on this yet? I would gladly give up the current tow haul mode to be able able to lock out 4th, esp. in windy, hilly 50 mph country. There has to be a way to do this . Anyone???`

 

I believe I read somewhere on another forum that if you hit the tow-haul button twice that it will cut out the overdrive.

 

In 2006 they combined the Tow/Haul and the 4th gear lock out.

 

You just cant lock it out on a stock 05 48re. Theres one guy trying to get a class action lawsuet going to make Dodge put it in the 05s . Was on this site I'm sure.
The 06s have the tow haul and 4th lockout . Seams all it would take is a reflash to update the 05s. But Dodge must give the info to the dealers before they know what to reflash. Just keep at the dealers or to Dodge. Dont feel too bad ,you cant lockout the hemies eather or the great ferd trans. The engineers are sleeping when they build a auto trans for a truck that you cant controle the gear selection when you need to. And they insult a good driver and show there ignorance, when they try to tell you the computer is so smart it will keep it in the right gear at the right time all the time, HAHA

 

See, I've been playing with this. There was someone a while back who said that his '05 acted just like the 06. I was cruising on the highway at about 60 the other day, and just hit the tow haul button. RPMs jumped up, and stayed there. It wouldn't upshift. Any one else try this?

 

My truck does this too, but after about 15-30 seconds it goes back into od.

 

yeah this sucks i wanna be able to lockout overdrive too!!

 

My new 05 comes tomorow so I will give the double click of the tow haul button.I am real excited about the Mopar pac brake that I am having installed on the auto.

 

check out the earlier threads in this forum we hashed this thing to death.

i have and several other have complained to our regional service reps the NHTSA our dealers etc.

if we had 50 or so we could do the class action

you can't lock out the od period. regional rep told me the pac brake option would chew up the tranny. because it was a p.o.s.

i finally decide to fix the pos myself with parts available from ats diesel performance here in denver

DC put together a real pile of parts imo

 

Rockhound,
Keep us posted on your results with ATS. There one of the best .

 

.....uuummm I believe the factory approved "jacobs brake" is available on the 06 model, not the 05.

 

I'd like to know what is different about the '06's that make it work for them. Why is it just the 05's that can't handle it?

 

You are right about not being approved for 05. The dealer told me when I bought the truck that the Jacobs brake was approved so I had them install it .A day later they called me and said they could not make it work unless they installed some after market stradegy box. Guess what in comes BD with a tow loc, of course my install price goes up and I was ready to have the brake taken out. I finally had them complete the install after they told me that it would be covered under warranty. All I need now is to get them to put it in writing.As far as the brake is concerned I have to drive it for awhile to get the feel of it and then visit BD for some fine tuning. I may take my laptop with me because the stadegy box is computer controlled and I can fine tune at a later date as things may change as far as towing is concerned.Sorry for the long ramble.
