g'Day Lee,From the 'Where did you go with' thread
I do have questions about the A750. When I checked Toyota of Cool Springs the tranny that fits my FJ (13) only fits 2012, 2013 and 2014. Was wondering if anyone knows the difference in years. 2007 only, 2008 and 2009, 2010 and 2011.
Is the auto transmission part of the tune the same for all years?
In 5th when the TC unlocks the temp rises rapidly. When it locks back up the temp drops rapidly.
If you drop from 5th to 4th and it is unlocked the temp still rises rapidly, but when it locks in 4th the temp rise stops and will VERY slowly drop. Very slowly. Is there something different about the lockup in 4th and 5th?
I read somewhere that there is a third condition besides locked and unlocked for the torque converter. ??
The tranny definitely acted differently going up the mountain. Better. The RPM running in the area of the increased low/mid torque. I'm sure that figures in there also.

there are about 6 versions of the A750 ... give or take....
Here is some home work for you... hahaha
Normal for temps to increase when it unlocks / or partially unlocks .... the new shift points can't stop the temps ...but they are much better managed with the new shift points
there is a"3rd" condition ...partially unlocked .... but I am old and forget when n why ... I'm sure its in the manual... some where
so I'm guessing ...the tune and shifts make Jade better ...and more fun ? Just holding gear longer up inclines and pulling stronger ... make it fun .... gone is the slug crawl ..especially if you loose momentum and try to get it back....
doesn't bog .....
