RX450h transmission replacement cost

[WXL]

My first service of a 2010 RX 450h shows a leaking tramsmission with a warning that it might have to be replaced.  I understand it's a sealed unit.  Any ideas of the cost of this?  Depending on that, I may take it back to the trader who sold it to me.  Many thanks.

If it's in warranty just get it straight back, don't mess about.

When did the Trader sell you the RX Wyn ?

What sort of warranty were you given ?

Be interesting why it's being suggested it might need to be replaced. Who/why?

If it's a recent purchase, can you reject it ?

Or the seller gets it fixed at their cost?

Record everything agreed in writing?

Did you have it serviced a a Lexus dealer if so get a quote for repair and take the quote to the dealer you purchased the car from .without any more info that's all anyone can suggest at the moment .

I would endeavor to get my money back from the trader.  If you leave it to the trader to fix it for you and they are prepared to do this, you might end up with a unit he has purchased from a breaker that may be oil tight but has covered many more miles and who knows how long that will give satisfactory service.  Are you prepared to take this chance?

Many years ago I bought my first BMW, a 528 petrol of about 1997 vintage.  The air bag warning light was on and the trader agreed to pay for the cost of a BMW dealer doing what was necessary to fix this.  I took it to a franchised BMW dealer   who said while investigating this that the car needed a replacement bottom end because it had the 'Nikasil' problem, (premature failure of coating on cylinder bores), a widespread issue at the time.  In view of relatively low mileage BMW agreed to replace the bottom end FOC but would not pay for pulling the motor out and transferring the existing head onto the replacement block and refitting.  This would still have been expensive and the trader refused to pay for this.  He said he could buy a used engine from a breaker and install this for £500 and offered this instead.  But I bought the car on the strength of it being low mileage and was not prepared to chance any used engine of unknown provenance being fitted.  Luckily the trader had previously collected it from the BMW dealer as I refused to drive it.  I took the case to the small claims court but the dealer failed to attend and the judgement was given against the trader who failed to return my cash.  It wasn't until the trader was told that bailiffs would be attending his premises to remove cars that he responded and I got my money back.  So persistence paid.  

As a point of interest, does anybody know whether there are any independent specialists that rebuild Toyota/Lexus transmissions.? There are many that do conventional manual or automatic boxes of course.
