Neste skritt tror jeg blir econ lock, men er det vanskelig montere selv, eller krever det verkstedbesøk?
&th gir er et problem på lc 200

Shift Pattern of Automatic Gearbox:
Although the hardware of the AB60F-Gearbox seems to be close to perfection, someone at Toyota must have been a bit crazy, when they programmed the ECU to control the gearbox.
There are two issues to complain:
1) gear selection
Below 115km/h there is no chance to get the 6th speed engaged and getting the 6th speed activated, it requires some “tingling” with the acceleration pedal to succeed. This problem got partly fixed for Australian Customers only with a software patch, which required to be activated every time after starting the engine. This patch now permits the 6th speed to be activated at 95km/h already.
In lower speeds the gearbox gears up very late at low engine load, so the engine cannot deliver the giant torque.
2) converter lockup activity
Driving in “D” means, that the ECU never locks up the converter below 100km/h (in 5th speed) and below 108km/h (in 6th speed). At speeds around 60km/h the ECU only performs a “partial lockup”, which is absolute nonsense, because the ECU does not permit to deliver any significant torque trough the converter, the smallest movement on the acceleration pedal causes in immediate unlock of the converter.
Driving in “S-Mode” and “S-4” preselected, the ECU permits a full converter lockup at 80km/h, in this gear the engine has to deliver more than 2000Rpm.
Also, when using the engine brake effect by manually down gearing, the ECU does not lockup the converter, the effect is, that the engine brake effect is worse than poor.
There is no possibility to reprogram the ECU, Toyota is ignoring this issue successfully since two years and there are some reports, that this problem is not only a Land cruiser-problem, there are rumors that also some Lexus-models are effected.
How does the driver feel this issue:
1) horrible fuel consumption, especially when towing heavy trailers
2) terrible bad engine brake effect, especially in the mountains dangerous.
3) steam ship like heavy behavior, can´t feel the real power of the engine
4) extreme slow reaction of the ECU at “down gear commands”, take up to 1,3sec.

Men jeg tror desværre at econ-lock er den eneste løsning på problemet:
Land cruiser 100 og Bj 43 Japan import .
Those who say that it can not be done , should not interrupt the ones that are already doing it!!
