My ute has gear ratios of 4.489/2.337/1.350/1.000/0.784/0.679/final 4.550. The 1st gear is really high with top speed of 20kmh at 2913rpm or 30kms at 4370rpm.

I imagine most manual utes have similar gear ratios. How do you manage the creeper gear on streets? Its sooooo slow and sometimes embarrassed for holding up traffic behind me. Any tips will be appreciated.

My little 4wd has 1st as a creeper/crawler gear and is very low so I just use 2nd as my drive off gear which means my 5 speed is used as a 4speed with 1st only used when a low gear is really needed.

When taking off, if you use the 1st gear for the first 5 metres of forward travel, ie to get the vehicle mass moving, then change to second, I can't see any problem at all. It is what most drivers do.
A 4wd ute isn't a race car or drag car so if you are used to petrol revving engines then learn to use the torque of the engine.

I know you said 1st gear is really high, but in light of what you are saying you are really meaning it is low. ie High ratio numbers = low forward speed for same engine revs.

Why you would want to rev your diesel engine to 4370 revs is beyond me as there won't be any advantage to revving it above 2500rpm in lower gears anyway. You have 6 forward gears mentioned. They are there in order to be able to match engine speed and torque characteristics to the load/mass of the vehicle and road conditions.

Most drivers change 1st to 2nd at around 1500rpm to 2000rpm max.

Have not revved beyond 3000rpm yet. 4370rpm is only a calculation based on gear ratios to reach 30kms.

If it is a diesel just a little word on lower gears. In heavy transport, you never rev out in the reduction gears. You short change and use the next gear, as your torque is there and your gearbox loves it.

Anything with a small capacity engine and especially a diesel has this problem..... It's called lake of torque down low.

They have to use such a low gear for when towing or loaded they would have troubles getting mobile.

Most modern utes have a good first gear until you put bigger tyres on and a bit of weight...... We had this problem with our D4D when towing in the high country.

The new Ranger and B50 3.2lts have a low first gear obviously to help when loaded on a big hill..... This is what made us buy an auto.

I can see the appeal of auto but I love manual too much. No issues working around low 1st gear. I am slow kind of guy so traffic have no choice but to bear with me :-)

Seriously.... me and my partner have always been manual people including owning high performance cars in manual later switching to auto's.

The only thing we have manual now are our service vans and trucks and more then likely when they get up dated they will be auto's as well.

The only down side of the auto is engine breaking but the new Ranger in auto will think smart and select a low gear and lock the converter offering very good engine braking and speed stability.

It's funny how one changes for the better.

No doubt those high-end auto utes are great. I have a limited budget for a new ute so the only ute around that fits the bill is either Great Wall or SsangYong. I find GW dreadful and SY a much better machine so the rest is history.
