Posting this for a friend. He has a 1994 D90 which the PO had the manual tranny replaced for a stock LR auto tranny. The problem he is having is when he goes downhill in D, 4Hi or 4Lo the D90 has no slowing power so he has to ride the brakes. I thought maybe it has something to do with the tranny swap or is this a common occurrence and easy fix? Thanks guys.
D90 Downhill Woes
- Thread starter Cambo
- Start date
Any idea if they fitted the kickdown cable? How does it shift when accelarating? Or kicking down to a lower gear?
Wait, I read the post again: Is he in low range and moving the gear lever to "1"?

very easy fix - sell the D90 as he has no idea how to drive it.
seriously, does he have any idea on how an auto tranny works??

its a auto...you are not going to get engine breaking from it...just learn to modulate the brakes correctly.

What are you talking about? Of course you are going to get engine braking, especially when you are in LOW range.
In my truck, 1st low is about 3 mph at 3k rpms. If I had to rely on brakes alone I would be dead by now.
My ST has 4.11's and my 1st gear in low travels at about 5-6MPH and that is fast compared to those with stock gears.

really?
enough that you can leave your foot off the brake and let the engine handle the work like a stick?
BULL SHIT...unless we are talking really mild down hill stuff.
if you are nosing down ledges with a auto box rover you are using BRAKES.
It is really good that you know so much about off roading...
Maybe it is different in a Disco, but in my 90's, I can take my foot off the gas and the brake and roll down a hill. If it is incredibly steep, I may lightly touch the brakes.

not really sure how to take that:rofl:
LOL sounds like you dont do much steep stuff in "your 90's"
I've had both feet on the brake pedal going over ledges while traveling down steep hills. I want to upgrade to more powerful brakes.

yeah yeah.... so maybe I need to fix the gizwadger, and the LMNOP valve needs cleaning.

oh hey and just to make sure there isnt misinformation in this thread.
your lower gears make your truck go slower not faster
a truck with stock gears does not have as low a crawl ratio and low is slow
just to be clear
wow!
an auto aint going to handle like a stick period! Does he have big tires & stock gears??
:iamwithstupid: LOL

So are all the brainiacs here really saying that an autobox in first low will not rev and control the speed of the vehicle? Is that what I am reading here?
Get real, a properly functioning automatic will act just like a manual transmission as long as it does not shift to a higher gear. If it does shift to a higher gear then something is wrong with the transmission.

The point to this post was to figure out why this guys Defender was not slowing down while driving down hill in 1st gear in low range. This was not intended to be a conversation about using an under-drive or crawl box. My point was correct; an automatic LR in 1st gear in Low Range should travel down a reasonable steep hill, on dirt or gravel, at about 5 miles per hour. This truck would be completely controllable without using much braking. This had nothing to do with rocks, ruts, ledges or a 70 degree hill, that is an entirely different conversation.
Concerning my truck with 4.11 gears, driving on my 33” tires, the wheels spin faster than they do with my 35” tires. That was my point. The 4.11 gears with 35” tires the gear ratio is closer to the stock configuration.
