Hi
Kimba
I'm familiar with all the standard arguments and the auto or manual
thing is quite interesting and more subtle than I first imagined.
Having both I can't win or loose but I have been on a mission to
make my later model auto 4800 match or exceed the manual.
I have, on balance been unsucessful so far.
The one big thing you mentioned (downhill braking ) was shocking in
the auto but I fitted 2.88:1 marks adaptor gears into my transferred case and that has closed
the gap as the Patrol already auto-locks in low low.
The hysterisis and lack of precision with the auto makes it hard to control.
Had this happen on weekend trying to position car steep uphill against a fenceline. With clutch you can dial in exactly what you want.
In sandhills my auto wins (just), but a previous matched competition
showed it took a huge 22% more fuel to do so.
On the huge moguls of the
Madigan line I nearly got trapped and I believe
I could not have extracted myself with my auto, whereas in the manual
I was able, using fine control with clutch and gears, to
rock back and
forth and get out.
I think when you make these comparisons the results may be car specific.
E.G. The 4800 GU Patrol manual has more power and a significantly wider
torque curve than its V8 100 series cruiser rivals which means that use of gears
or hills etc isn't so important.
I will keep trying and there is one way the auto always wins -
when I wander out to the car half asleep like this morning,
I open the car door and just insert the key and start the car without
getting in, letting it warm up for a few seconds while I wipe dew off the
windows.
Can't do that with the manual.
