A little while ago, the transmission on my 2013 LC200 failed and I had it carted off to 'Wholesale Automatics' (WA) in Melbourne.
After a little discussion, I agreed to have the transmission upgraded with all the heavy-duty parts they normally have,
the Nomad valve body and their accessory oil cooler.
It all came back, running like a dream, I had a look under the chassis at what I could see of changes made and spotted
a rubber hose associated with the oil cooler that have a very, very tight bend in it. I thought at the time that it didn't look
right but thought 'they know what they're doing' and promptly forgot about it. I was wrong.
Some months later on the wife and I and our 18 foot Jayco Expanda were heading across from Melbourne towards
Hahndorf, SA when my I noticed that my Scanguage II was showing that the transmission fluid (TF) temperature was slowly
rising above normal. I have a torque converter lock fitted which activates above 60kph and hadn't seen such temperatures
since fitting that. We nursed the car into Hahndorf as best we could but had seen TF temperatures well over 100C nevertheless.
Leaving the caravan at Hahndorf we crept into Rowell and Searle Auto Transmissions in Adelaide.
After some time running a battery of checks, they finally realised that one of the accessory oil cooler feed pipes (you know
which one) had kinked, totally blocking TF flow through both the OEM and the accessory oil coolers which are connected in
series.
Rowell & Searle contacted WA who refused to accept any responsiblity for the failure.
Apparently WA buy a 'kit' from somewhere and fit that same kit to a wide range of vehicles - nothing wrong with that but
it appears that the rubber hoses in that kit aren't quite long enough for the LC200. Rowell & Searle have fitted many of
these kit to LC200s but substitute one of the rubber tubes with a significantly longer one, having seen the tight radius that
results if the original tube is fitted.
Since that time I have not seen TF temperatures above 70C (stop-start suburban driving, hot day, caravan on the back.).
and that was with a lot of speed too low to activate the TC lock and accelerating after stopping.
I thorougly recomment both the TC lock and the oil cooler but - buyer beware!
Attached is a printout of an eMail ad to me from WA.
