noticed it today. (Overdrive is on and ECT off) when cruising about 50-55 etc I think maybe there is another gear to go into >> ??
Its only doing about 2100 RPM etc (which to me is good) but still feels as if it would love another gear!
is it me , the car or what??
cheers !! |

60mph should be just a whisker over 2000 revs

I have mentioned this about my own landy in another post somewhere? Yes mine too seems like there should be another gear it should go into!
I also find it quite annoying as on the flat it is waisting so much fuel. Although the gear box is silky smooth up and down I am not sure how many gears it actually has I'm sure the box is supposed to be a 4 speed auto with overdrive, so that makes a total of 5 gears ? so in that case why is it when only doing 40 mph and I switch off overdrive the car immediately drops a gear and when I am doing around 50 mph it changes into top gear. It also seems to have intermediate gears when it does change up in the higher gears it seems to go onto a half a gear extra then while the speed is increasing another 3-5mph it finally goes into the fixed gear as if it's testing to see if the gear it changed into is the right one. I just find that very odd. Other than that I'm very happy with it's performance except for cold starting which is slightly only very slightly tempermental. It won't start unless I depress the accelerator the same way a petrol car starts. But this should have no effect on a diesel as there is no pumping extra fuel into the engine with the efi setup! Once started it gives out a small cloud of smoke then after about 10-15 seconds settles down and is smooth as silk which is another odd enterty?

Your gearbox should be 3 speed + overdrive, and what you are saying about it changing at 50 mph or over is the torque convertor locking up, on my Surf this happens just under 55 mph.
