diesel consumption

[frank rabbets]

Hi Paul

Yes mine is 4 speed auto. [the 80 being manual].I would like to confirm there is something wrong rather than driver error before I take it back under warrantee . Last time when the diff lock was "seized on" Jon pointed out that I had pressed the button !

HELP

Frank

I thought you'd got the 5 speed Frank, which is 4 speed plus OD. You haven't got OD switched off have you?

 

[Paul]

Sorry, mine is 3 speed plus OD

Hi Jon

Looking at the Toyota Car Data Archive my Amazon 2004 should do 26.6 mpg combined but it does far lower than that. I have not yet found the RPM per MPH figures so shall start searching.

[Jon Wildsmith]

I'm pretty sure that RPM at 70mph is wrong and is more in line with the rpm expected with OD switched off. Does the 5 speed still have an OD button like the old 4 speeds and if so does it have any effect when you use it at 70mph?

 

[Jon Wildsmith]

There's no mention of OD in the FSM but it shows a 'pattern select' switch (labeled ECT or Power on older trucks) have you experiemented with that?

Hi Jon

Much to my benefit you are a genius at stating the obvious !
It was described to me as a 4 speed auto so I have been driving it in "4". If, in the same horizontal plane, I move the lever left to "D" it effectively becomes a 5 speed and I assume this is the overdrive position so effectively you were right and I have been driving around with overdrive turned off. Anyway what a difference! Now 2000-2200 at 70mph and MUCH quieter.
In my feeble defence I have never driven an auto with 2 options in one horizontal plane, this box has "D-4" on that plane and I had assumed that this was just the top gear option and to make sure it was in a secure position I had been moving the lever to the rhs of this plane. I assume your auto has not got the same layout otherwise you would have spotted my mistake?

I've only done a few miles so far in it and only 2 long journeys so shall look forward to seeing the difference in fuel consumption.

Thanks

Frank

Classic case of RTFM :rofl:

 

[Jon Wildsmith]

aha, another good result The old 4 speed box like mine is just a straight shift with no sideways movement but now I know more about the 5 speed box shifter

Is it like this, ?
This is what the 120 auto stick looks like

Yes D4 is either D or 4

[frank rabbets]

I must learn to post pics. My lever runs through an open slot with the letters and numbers printed on the rhs of it. Had they printed the 4 to rhs of the slot and the D to the lhs it would be much more obvious. At least the posted picture of the 120 has little white dots to show you where each position is and 4 is obviously to the right of D.

Here's the shift pattern of the LC100 gated shifter, with altogether 8 positions:

 

[frank rabbets]

THANKS!!

The circle in the middle of the slot represents my gear lever. I think that the "D" and"L" should be on the left hand side of the slot so thick people are not fooled. Any more with this opinion!

Frank

 

[Jon Wildsmith]

I bet plenty of people have been fooled by that Frank, not really very obvious that D-4 is depicting two positions!

 

[frank rabbets]

Now driving in "D" rather than "4" I get 27.5 mpg on a run.

[Jon Wildsmith]

Close enough to your 80 to be happy with?

 

[frank rabbets]

Very much so, and so much quieter in the right gear; or was it left? I wondered why people rated these 100's. Now I know. Thrilled to bits and building a carport for my 80 to protect it from the sun and ice. Oh yes and stones over the stable wall. Was'nt you Jon in a fit of jealousy?

Frank

 

[Jon Wildsmith]

That's not good, can't think why that would be happening

 

[frank rabbets]

No complaints Jon; just kids who think that it's just a wall with a garden the other side and toss a stone they step on over it. I'm not at all worried.
