Finally found the tranny limit
I guess I finally found out how much power my truck can comfortably handle this last weekend. I got a chance to pull my trailer down to Virginia, south along I77. This was after Momma had loaded up the trailer with all the goodies for our annual vacation. Before now with this trailer we have only done short runs, but this time we have got to take everything. I think she cleared the house. On one of the long grades, I had to back out of the throttle due to my transmission temperatures starting to climb too high. At one point I saw over 230F on the transmission temp gauge, and that was in third gear. I found that the most boost the transmission could handle for long periods was about 14 psi. I think 13-14 psi is just about what the stock truck is good for, so it looks like Dodge hit it just right. It was a strange feeling being able to play the throttle while watching the temps rise and fall with boost.
Oh well, now hoping I get chance to save enough money for a new transmisssion, before the old one quits.

Good to hear that she didn't give out on you and got you back home.
The stock tranny in my 99 didn't care much for the grade climbing Black Mountain on I-40 either. It did not want to stay locked up in 3rd gear and the temps rose fast.
The truck really likes the tranny upgrade that I have now and it has made a big difference.
Just remember John,
Talk very, very nice to the truck until you can get it refreshed,,,,,,,,,,,,

Is there a way to put a locking TC in the 518 in your '93? I pull 23psi when towing our 5th wheel uphill foot to the floor in O/D and tranny temp doesn't get over 160*F. (pic in gallery at left) It gets hot backing it into the yard though.

I suggest an AT fluid flush and total change. I lost the link to a chart showing AT temps and fluid damage, but I seem to remember that 230* cuts the fluid life by nearly 3/4. Are you locking out OD? This will hold AT hill climbing temps down. Do you have a 4" exhaust? that too will greatly improve performance on hills.

1st three Dodge Cummins trucks were great! The '03 was too except for the driveline. I waited patiently for almost two yrs for a TSB or a fix even if I had to pay for it. I'll be back when Dodge figures out how to put the Cummin's power to the road without bandaids and unusual vibrations. My ring & pinion sounded pretty rough after a 1400 mile trip for thanksgiving. I can't go with a P of SD or Dmax so the thirsty Hemi will do for this time around. I'm very happy with and it's performance both motor and the 5spd tranny. If DC could beef up this 5spd auto for the 610 Cummins, THAT would be sweet! It has a real tow/haul mode with two O/D and two 2nd gear ratios. Just what we need for the Cummins to keep it in it's sweet spot.
