I would say the transmission ECU may just need recoding but any automotive electrical specialist near you should be able to sort it. At least you could then eliminate this as being an issue - does the transmission look new or even as though it has been removed and replaced?

hey guys my name is Mario and I have an issue with my 2006 lexus gs430 this is my story: I just bought the car recently and the previous owner told me that he lost all gears all of a sudden and that it needs a new gearbox and a ECU recalibration he told me that his mechanic told him that he needs those work done on the gearbox ( valve body , line pressure solenoid, lock up solenoid ) he said better change the whole gearbox i dont know !!! and in the electrical side he said ( sold need to be reflowed and IC ( transmission control ) plus the ECU needs recalibration or something due to heat damage. he also mentioned that I can send it to ( relentless motor ) in texus , United States but I need someone in here sydney Australia that has good experience with those cars. NOTE: the car goes into ALL the gears and moves except the D ( drive gear ) it won't move and I can hear a clunky noise. my mechanic told me thats there is no issue whatsoever in the car when he diagnosed it except two codes relating to the transmission and the solenoid not getting information or instructions from the ECU. something like that Can you guys help me with what do you think the issue could be ? a bad solenoid, bad valve body, or an issue with thr ECU ans if changed to new one or recalibrated could solve the issue?? or if you know a good car electrician that has good experience in those old V8 that will help alot.

Sure thanks. Its just its my first car and i’m a bit of an overthinker so i just have an extra attention to weird things. Are there any tips for things i need to keep an eye out for specifically.

any independent workshop should be able to tackle suspension component replacement unless you're after bespoke performance suspension mods in which case you will need a specialist to set all this up correctly - good luck, hope you find a good one!

oh dear, sounds like the other garage mis-diagnosed it then - but keep an eye on it as it may be that the previous garage had the suspension loaded (weight of vehicle on it) rather than unloaded where the play not have been present.

The best place to gat suspension work carried out in Perth?

I had it checked with another mechanic, he lifted the car and tried wiggling the wheel, it was study and no moving also examined the lower control arm and said its fine.

It certainly does sound like the lower control arm as this has swivel joints and rubber bushes which if have wear will produce freeplay which is what you have and I would replace the whole arm rather than battling to install bushes and joints
