avg crawl ratio ?

[bigdog165511]

You need to stop using online calculators and use a real calculator. Just multiply all of the gear ratios together....For the transmission only use the lowest gear...

For the torque converter debate I've learned from experience that the lower your gearset is the less give the torque converter will have. Once you hit about 100:1 or so with a stock converter it's effectively 1:1 and you no longer need to factor it in.

Cool thanks dident figure in tire but says 302:1:awesomework:

465/203/205 with 4.56 in the diffs===114 to 1:awesomework:

 

[johny5]

66:1 with the 4.3 th350 5.44:1 4:88

 

[TreeClimber]

I'm about 40:1....works good:awesomework:

Well that's just impossible. Haven't you read the internet. If you ain't 100:1, then you just can't four-wheel. (BTW.... do you even have a high-range?)

 

[jeepmauler]

Yes I have high range.

I've substituted a low crawl with torque and anger......results vary.

Jeep

AX-5 Tranny
Atlas 4 Speed 10:1
4.56 diffs.

186:1

I rarely use that on trail wheelin, but in rocks with my 2.5L four squirrels of fury, it is nice.

Normal trail wheelin I use the 3.8:1 in the xfer case which gives me about 70:1 ratio.

......results vary.

:haha::awesomework:

I'm a Mauler nut rider.

57 2 1

 

[NotSoPC]

Sammy trans =?
Sammy t-case =6.5
Toy axles =4.30

I have no idea what the 1st gear in a zook is.

 

[rubikong1]

TJ, 5 speed, 4:56 gears, 37" tires, I'm around 79:1 which is not bad for what I wheel, but it is a little high when I get into the rocks or tight spots.

What calculator did you use? I want to use that one!
I've tried 2 different ones and come up with 50.65, and 50.8.:booo:
TJ (97), 5 speed (ax15), NP 231, 4:88 gears, 37" tires (not a factor) = 50.8
Maybe you forgot to mention your 4:1 kit or something.

 

[TRG4runner]

R151F tranny, stock toy case (2.28), d300 4:1, 4:10's works good but could be lower :redneck:

 

[Kat]

RubyDoo had 3.8 V-6 with 4.26 first gear manual trans, 4 to 1 transfer case, 5.13 gears on front and rear diffs with 35's that equaled 93 to 1 final

 

[no excuses]

another 4.3 turbo 350 with 5.44 tcase and 4.56 gears

guess that comes out to 62.5: 1, with a 2200 stall converter and 40"s it works for me (when I wheel :looser. plenty low for me and the ability to grab gears with the auto when I need more speed.

 

[jeepermc]

NP435 6.69, 18 @ 2.46 and 4.56 gears puts me at 75.05.... Works good with 35's and a 289

 

[Metalbender]

speaking of crawl ratios has anyone done rim rock specifically chicken **** and blue slide with an auto???

 

[TreeClimber]

Yes. It's much easier.

1st Jeep, CJ5, T18, Dana 300, 4.27 gears in the axles on 35s.
Current Jeep, YJ, TH400, Atlas, 4.56 gears in the axles on 37s

Going uphill, the auto is able to shift gears to maintain tire speed when needed
Going downhill, plenty of compression braking due to 4.3 low gear in the Atlas.

 

[Binder]

All wheeling is easier- better with a auto...God gave us two feet to work two pedals.:;

 

[Metalbender]

for long down hill compression do you run a reverse manual valve body so the tranny does not shift?

 

[TreeClimber]

I have a conventional valve body. It's neither manual, or reverse pattern. It still has plenty of compression braking.

 

[Metalbender]

Binder are you telling me that god shorted you a leg for the 3rd pedal??? Boy id be pised...
