Thread: Auto conversion

Ummmmm, ever though of pulling the hand brake on a couple of clicks for that 1 or 2 odd occasions that you would need to creep down something that slow.

Even the foot brake and drive through it to keep the converter working.

There is no real life situation which cant be worked around in a safe and relatively simple way.

I can tell you that even on 31's, my engine braking is still better than a standard Hilux or GQ pootrol in low range, my mates are always hanging right back on long decents and I just let it go and by the bottom they are hitting the brakes in thier manuals and on the radio for me to speed up so it cant be that bad.

I'd rather trust my mechanical components than trust the friction on my brakes for long descents. The hand brake works on the transmission via a drum brake, it's extra wear on it and IMHO it can be dangerous.

Look - I'm not bagging out the auto. I love the idea I really do. But to sacrifice the ratio that I have after spending over 2k to get the transfer case where I have now doesn't make sense to me.

Riding the handbrake on the LT230 stuffs it pretty quickly. I found this out when being flat towed up at Cape York with a broken radiator.

What's your final ratio in first low in your vehicle Slunnie?

Good question. Here are the ratios. I also run these on 34"35" Simex. I've not ever had a gearing problem with these ratios or needed lower than L1, but thats not to say that there isn't better ratios out there. For engine braking the ZF4HP22EH locks up in all gears in low range in overrun, so this definately helps, and then I just supplement with the brake as needed. The 4HP22 does not do that.

ZF
1 2.48 (12.33/33.84)
2 1.48 (7.36/20.19)
3 1.00 (4.97/13.65)
4 0.73 (3.63/9.96)
R 2.09 (10.39/28.51)

LT230
H 1.21
L 3.32

Diffs
4.11

Why ask the question about the conversion and then argue the point over ratio's.

You would have to be on the brakes for ages for it to make any difference to their wear and temp.

Everything is a compromise, your low gearing will still be better than mine and a hell of a lot better than anything else on the market so if you want an auto then thats the compromise, dont go bagging it and dont go saying that these tried and prooven ways of driving them is dangerous when it's just as likely you can grab and axel and snap it and the car turn over or drive it'self off an edge as it would be for a brake compnant to fail and cause you to go down the hill still slower than a Pootrol.

Ive been using this tequnique for 4 years and the shes are still like new, I change my pads about once a year depending on driving.

I generally use the handbrake as on a lot of the decents we do there is a river at the bottom and I dont like quenching brake rotors, they normally dont like it.

Nope. I've read this 200Tdi box onto 300s thing being faster, but I don't see how. Exact same box. They both use an FTC2756

Settle sunshine.

Did you even read my posts properly - or did you read what you wanted to read? I do believe that I said IMHO - in my humble opinion.........

I wasn't having a go at you or wasting people's time. I asked a fair question and continued doing research on it. I now know (and probably do others) what is entailed in this conversion, and I also now know the ratio's -which I didn't before. IN MY OPINION, the ratio's don't make the conversion worth it for WHAT I DO with my vehicle. I do appreciate the help I've gotten on this thread - hence the thankyou's on some posts.
