How did you get on resolving the issue, did you find the cause

Gravesend

I’m having same issues with auto TT, gearbox doing weird stuff but i can’t find or fix the problem I’ve changed gear boxes, torque converter, with new filter and oil, sent ecu off for repair, swapped ecu over with another but still no joys, it’s definitely an electrical problem than mechanical, someone must know how to fix the problem or what’s causing it

Update, problem developed into and bigger one now car won’t change up gear, I was told it would be gearbox so I changed the gearbox again with OEM torque converter from a running car so I know it’s good and it’s still the same, so I know it’s not mechanical but definitely electrical. I havent tried swapping over the traction control ecu yet as can’t get hold of one to try, not sure what my options are now. What controls the auto box and tells it to change gear

I’m trying to diagnose a weird electrical transmission problem so want to try swapping over traction control auto ecu to rule that out

Pm

No what could it be on the throttle body, is there anything I can check. Now the ecu sorted it might now record an error code fingers crossed

Update, I took the ecu out and found a couple of capacitors had blown / leaked so I sent off the ecu for repair had all the capacitors changed. It has fixed most of the problems, overdrive now working, auto box now back to normal with changing up and down gear and powers back but I still have the overdrive light flashing and slip con light on.

Think srd tuning has a guy they send ecu off to be repaired

I can rule out the odo swapped it over with another one to test to see the overdrive would stop flashing but no change

I did read on here that possibility could be the speedo converter, might be worth a shot changing it, so i thought I’ll check it out, doesn’t look the best installation and unsure what brand was used

It’s got to be something electrical or a sensor I’m guessing

These are the lights showing on the dash when driving, slip control not working and overdrive doesn’t work IMG_8384.mov

Managed to get the display working where the engine lights is, but can’t read any error codes as it’s just flashing constantly without any pauses IMG_8382.mov

Tried checking the error codes with the paper clip trick but seems the engine light display not working

Can’t someone 3d print one

Battery fine, just seems really strange it was all working fine now it’s decided to play up

I had a problem with my auto box where it just kept slipping when putting the power down as the clutch packs had gone so I swapped it over with a uk spec auto box with new filter and oil and also fitted a titan 3200 high stall. Supe drove absolutely fine but I had some lights flashing on the dash. The overdrive and slip con lights are flashing alternately to each over and the main triangle light is very faintly on. Then the overdrive bottom stopped working as in it doesn’t pick up the revs now, the car still drives fine but now it won’t let me put any power down it’s like it’s in some kind of limp mode, seems like an electrical problem, any ideas or do you think the ecu is playing up thanks

Thank you, been trying to find the part number on google but with no joy and when I speak to Toyota there not really much help

Turned out to be the clutch packs in the gearbox slipping it just got worse and happening more often so i swapped the box over and changed the torque converter to a 3200 high stall all sorted now. The sup hooks up a lot quicker, so now seems more responsive, wish I knew high stall would make such a difference in a auto well worth doing

None of the links are working

Hi, can someone help me out please with a part number for this hose or point me in the right direction for an aftermarket hose thanks

Now sourced went with brand new uk spec set up

Hello mate, is this still for sale ?

Thanks for your input I appreciate. I’m seems to have got worse since changing the fluid and filter. Can you still get replacement clutch packs for the auto box
