Car dying :(

[Rory]

Hi all, I've been a member for 12 years but become dormant to stop myself spending money, I've a problem with my gearbox, 2 engine codes, they are intermittent leading me to believe the problem is less a mechanical one and more an electrical/sensor kind of thing

Does anyone know if it'll be expensive based on the error codes?

Thanks in advance

just had a look on the web,they both come up as electrical and are both transmission related,at a guess would probably say not going to be cheap as most things transmission related tend to be expensive

are you sure they just aren't silly little gremlins that really are not faults at all but simply electrical glitches that immediately clear themselves. with zero impact on performance or gearbox longevity..............  have you ever sought some professional guidance with this ? and i don't mean Lexus main stealer

well one of the codes is relating to the solenoid, I was recommended a local independent auto box specialist and he looked up the codes, gave me info that conflicted with what I already knew, so I walked away, I've done some more digging today and i'm gonna price that up with a change of gearbox oil, transmission fluid (is that the same thing?) and if its only a few hundred quid i'll do it, the car is still very tidy and only has 95k on it, theres another 100k in it yet

In the dim and distant past I recall a change of transmission fluid did the trick....don't quote me on that but worth a go first and foremost.

i've just had a search and come across a post on here from 2016 from someone with a 2004 GS300 behaving exactly the same way and he didn't bother fixing it 😕

i'm no mechanic and don't trust my local autobox specialist despite his handful of good google reviews, so i'm gonna go to Lexus Bolton and get a quote, Toyota won't touch the gearbox as they don't have the right equipment to connect to it apparently

 

thanks for the advice, i'll update once i've taken it in

What are the symptoms ? I'm just looking at @Malcs post above in this respect. 

A transmission drain / flush by an independent should be quick and cheap. Codes are quite indifferent in their meaning, often they will simply throw up anything if there is a change in the viscosity of the oil for example.  Will Lexus charge you for the diagnosis , I guess they will.
