When you brake on a steep grade in drive the tranny can quickly shift down 3 or more gears causing your rpms to get much to close to the redline (screaming).



You'll never convince me that is normal. And the manual advices you to use 'M' to prevent excessive rpms on steep downhills while also saving your brakes.

I would love to see that part of the manual, because I don't believe it exists.

Okay. You caught me I thought I had read it in the allison 1000 manual but it never actually says shift to manual from tow/haul to avoid over-revving. My mistake and also my tendency to shoot my mouth w/o verifying combined with selective memory.

I should of said that after scaring myself when the tranny shifted from 6th to 2cnd and the rpms were around 4k (redline is 4800) I read all the manuals and visited all the forums and my research led me to the solution of shifting from tow/haul to Manual and controlling the downshifts myself which ovoids the over revving situation when braking on steep downhills.

My apologies for turning my opinions/experience into 'facts'

I understand the need for engine braking - going down mountains as stated is not an issue. It's when it's a short hill and the truck tacks over 5k unnessarily that I trouble with. Then there is a long hesitation before it will shift back up when your trying to accelerate. Sometimes the engine braking is perfect and sometime it's over reacting to the situation....

Redline can't be 4800. Peak horsepower is achieved at 5500 so it is perfectly safe to run at this RPM, even higher. In tow haul mode you can't achieve redline no matter what you do as the truck's computer won't let you hurt the engine. Not true in manual mode however.

As for the short downhills try not braking, in which case the transmission should gear down one gear at a time as needed to hold speed, or lightly tap the brake for a one gear change, or just take it out of tow/haul for the downhill and use your brakes instead. 5K won't hurt anything, but I can see how it could be annoying. Your other option is to use manual mode. I am assuming it is a pretty steep grade if you are seeing 5K. Your truck is trying to keep you safe and it doesn't know it is a short hill. Try some of the other options above in this case. I have the previous Torque Shift transmission in my truck and the tow haul is designed well. I have over 10,000 miles of mountain driving experience towing my trailer, but no experience with your transmission so I'm going to bow out out this thread.

Red line 4800, tach only goes to 5k. I'm out of this thread also as evidently my point was lost long ago.

I guess I am the culprit here. I saw this thread a while back and revived it for some info about my new TV. All input has been appreciated by those with the same equipment or not. Reading the manual explains things from a small book in the glove box. Talking with folks who use the same equipment and have practical experience is priceless.
I am just trying to avoid leaving a trail of oil and parts behind my rig after going up or coming down from a significant grade.
I do not consider myself that stupid, but I would like to keep the word "Oopps" out of my vocabulary and my checkbook. I think you can all relate.
Thanks,
RMc

You're the man I'm looking for, and i have a question for you! I have a 2015 f250 6.2 crew cab 4x4 3:73 and we picked out a heritage glen or hemisphere 327re (same camper different names and colors) sticker on the two campers say 1800-1900 pin weight is about 10,000 pounds (before packed and loaded). My question is do you think this will be to much camper for the truck? We have no plans on going to the mountains, live in clt nc only going to disney and the beach. Thanks!

Oh and for everyone else I tow an average 6k 16 foot enclosed trailer all week and get 11 mpg, without the trailer I get 15mpg now if you have a heavy foot you can drop that to 12 mpg. So far its been a great truck.
