Hi Paul.  I suggest going to a diesel perfomance specialist. Toyota can't fix it - I went to three of them. Mechanics don't have the right gear. Auto electricians say it's electrical and suggest going to Toyota. It's not a gearbox problem - I tried all that. It ended up being in the ECU. The performance people did a 'remap' which cost about $500.00 which fixed it instantly. My car has never been chipped or tuned so it's about as standard as they come, but a remap? fixed my problem of no 5th/6th gear or cruise control and it's been perfect for a few months now. That's all I can suggest. Good luck.

Thank you. Yep it sounds like I have the same problem. No 5th and 6th and no cruise. Replaced the accelerator pedal and didn't change anything

The problem I had with my 2009 200 series with it not changing up to 5th or 6th gear ended up being an easy fix late last year. To go back to beginning - 8 months prior to the start of the problem, I had the intake manifold cleaned by a diesel performance company and they talked me into having an EGR blank plate installed and adjust the ECU accordingly, which I agreed to while I was there. Then 8 months later it started to intermittently not go past 4th gear. The company said this issue had nothing at all to do with what they had done with the EGR. The problem got worse over a period of 12 months and it became a permanent 4 speed gearbox. After taking the car to numerous other places without success I ended up back at the original company who had by then come up with a solution. They said it was basically in a type of limp mode, so they did a minor remap of the ECU of some sort and I think they turned off the EGR valve. Probably not legal but anyway. If I hadn't done the blank plate 2 years ago it would've saved me a lot of trouble. It's all good now though.

Yeah ok thanks. So if I get it retuned that could possibly fix the problem?

Hi,

I have the same problem with my 2012 GX LC200. On solid and cannot clear, 1 to 4 th ok but no 5 or 6th. Cruise control not working also. Have not changed the accelerator pedal sensor yet as would expect an error code and check light if this was the problem and not getting either! Had the auto transmission checked today and valve body and actuators working fine so definitely external to the box, getting the rest checked Monday but running out of ideas. Hard to isolate without any error codes coming up. Any help would be appreciated.

cheers,

Richard. Gold Coast.

Hi Richard, I seem to have the same problem on my 2010 gxl. Did you find out what's wrong?

Paul

Anyone with any luck. I also have a 2010 Gxl that won't go past 4th and 5th and also cruise doesn't work. I've replaced the accelerator pedal. Also when I disconnect the battery and reconnect it, everything works fine for about 5 min and then cuts out.
