im asking for a friend. i know there is a tsb or flash for high idle but is there one for O.D. lockout along with tow haul like the 06-07 48 re's have? my dealer was not sure.....thanks

 

No, there is one that takes away tow/haul and makes the 2005 a od lock out.

 

No, there is no flash for it. BD Power sells an add-on lockout box that uses the factory T/H button. It runs about $225 I believe. I have it on my truck and it is very useful when towing.

There IS a flash for it. As stated above it changes your Tow/Haul to a OD on/off button. Its one or the other, can't have both.

 

Oh, OK, I wasn't aware of a flash like that. But with the BD Power box I have, I have both T/H and OD lockout available.

There is a flash for the 05' auto's and I like it alot.... If you tow, you should get this flash. I had the high idle for the cruise control done at the sametime. ( and no, you don't have to get the stupid out of park alarm if you don't want to) . My dealer charged $0.00

SUBJECT:
Flash: New 48RE Feature That Allows Normal Shift Schedule With Full Disable Of 4th Gear Overdrive

OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Cummins Engine Control Module (ECM) with new software.

MODELS:
2005 (DH) Ram Truck (2500/3500)

NOTE: This bulletin applies to vehicles equipped with a 5.9L Cummins turbo-diesel engine and a 48RE automatic transmission (sales codes ETH and DG8
respectively).

SYMPTOM/CONDITION:
1. The following enhancement is included with this software:
a. A new 48RE transmission feature that will allow normal shift schedule with full disable of 4th gear (overdrive gear), when the customer selects the Over-Drive (O/D) switch.
Prior to the implementation of this new transmission feature, the use of the O/D switch changed the automatic transmission shift schedule from a “normal” shift schedule to a tow/haul mode shift schedule, and allowed 4th gear (overdrive gear) engagement.
This new transmission feature will not change the transmission shift schedule, but will allow full 4th gear overdrive disable (lock out). With this new feature the customer will have the “normal” shift schedule with NO overdrive (4th gear).

NOTE: To enable the new 4th gear disable feature, the ECM must first be
reprogrammed (flashed) with the latest software level, and then the 4th gear
disable feature “O/D OFF ENABLE” must be selected (turned on) using the
DRBIII®. Tow/haul mode is not an available feature whenever the DRBIII® has enabled the “O/D OFF ENABLE” selection.

thanks guys i will let my friend know.

it does suck that it has to be one or the other lockout or tow haul. both of those features together would have made my 05 when i had it much more fun to drive.
