The standard set uses the engine temp to warm the ATF fluid up from cold and vice versa when hot.
By having a seperate cooler for the trans you will need to take particular care that you warm the box up, i dont know if you have ever noticed that it doesnt like shifting in manual mode from cold? this period will take even longer
unfortunately what they have put in writing is that they cannot say for certain that the gearbox will not need replacing but they have done 2 recently and the box didnt need to be changed, new gear boxes are no longer available
right, really dont know what to do here, the estimate has come through but they are saying there is no quarantee that the gearbox will not need replacing too! anyone want an ISF😓
i've just spoken with Lexus Coventry and they are sufficiently happy that the solution they are providing will resolve all issues and will put it in writing too
transmission cooler failure.
best case they replace the rad and cooler, flush engine and gearbox, replace filter etc £2300
Worst case all of the above, disassemble and remove gearbox and replace solonoids in the gear box and reassemble £3700
so today this happened! was driving along and gear changes felt a bit funny, then all of a sudden lost all drive, pulled over straight away, turned the car off then watch the puddle grow!
on the plus side my tan is looking pretty good after sitting at the side of the A46 for nearly 4 hours!
not strictly true, BRIC fuels (Brazil, Russia, India, China) are often well under 95 RON, cars we produce for these regions generally have a different fuel system
