T-Case Info Needed
Does anyone know what t-case and its gear ratio in 2003 SD with Auto and 6.0L?
Went hunting in it this weekend, while it has all the power in the world, it does nothing to crawl down a rocky mtn side. Needed brakes all the way.

2.72:1, sounds like a lot, but it didn't drive like that. Yes, I had it in 4 low, according to the "****" on the dash, It felt more like 1/2 that gear reduction although top speed was probably 30mph.
It kept wanting to go about 3-4 mph, when less than 1/2 of that would have been appropriate.
Thanks for the info.

The next ? is whats your axle ratio?
What size tires do you run?
Maybe a dumb? ,were you sure the front hubs did actually lock ?????
It might not have actually gone into 4lo
We assume you were stopped and foot firmly pressing brake before you shifted into 4lo .
even though the light said it went in ,it might not have.chk it out on flat ground .
Me owning a 6 speed with granny low can crawl
at idle .up or down
Haven't owned an auto to try.

I had the oposite problem. I have a 6.0L CC with 3:73s. I had a yard of mulch in the bed and was trying to pull out a stump. The truck was on blacktop and wouldn't break the tires loose even in Lo Lock. The stump wouldn't budge and the truck just sat there. It was sad. I pulled out the Chevy 1 ton with 4:56s and lockers and snatched the stump out with all 4 tires smoking. It was a bad day for ford.

My axle ratio is the only one, I believe, is availible with the 6.0 and auto, 3.73.
The tires are the stock 265x75x16 BFG Rugged Trails.
No, I am not sure the front hubs locked. Although, I don't believe it should make a difference if the truck was gearing down.
Yea, I don't remember the detail of "how" I shifted into low range. (The argument for levers!)
I just thought I was told, or was under the impression from discussins with others, that this truck would just crawl when geared down.
Also, does anyone know if the tow/haul mode works in Low Range.

Did you have it in drive or first. When I first went from stick to auto, I forgot to shift into first for max compression braking. Drive will just let it run away.

I would try to go ahead and lock it in first. It also may the weight of the truck and the hill you were desending and the stock gearing couldn't hold it to 1-2mph and some brake was needed. Just a thought.
