CumminsDriver... your point is well made. it is true that
most transmissions do not lock the torque converter in first gear and this can lead to excessive transmission temps and poor (or zero) engine braking.
However, not long ago I had a mechanically bone-stock 48RE that could lock the torque converter in first gear...The only thing that was done to alter the tranny was the addition of I a simple pushbutton switch that grounded
one wire (pin 7 on the trans electrical connector) in the control circuit that locks the TC. See photo below.
So... getting back to the OP's original question, which was; "Any ideas on ways to solve the problem?"
Solve? No... But I have several ideas that, when used together, will make controlling downhill speed easier and far safer:
1) Install an exhaust brake. Jacobs make's one that's Cummins approved and basically plug-n-play installation on the '06 Ram CTD. If you need/want more engine braking power than the Jacob's, you can consider the PacBrak PRXB
2) Select the highest gear that will allow you to maintain the desired a safe speed, without needing to apply the wheel brakes. This may mean engaging the transfer case (if available) and selecting in 4-Wheel Low.
3 If you have a tow/haul button, use it.
4) Install a torque converter lockup button so that you can decide when to lock the TC. This is especially valuable while using low gears.
5) Flush and bleed your brake fluid annually. I use a
pressure bleeder from Motive Products6) Use high quality brake pads and inspect them frequently. Amazingly, I have had
great results with the Autozone Severe Duty pads on my Ram 3500.
7) Never ever "ride" the brakes. While descending a grade, keep your feet off of the brake pedal until you need to decelerate.
8) If you tow, invest in a high quality hydraulic over electric controller such as the
Max Brake.Hope this helps,
