SORRY! But Land Rover instructions in the Shop Manual are just incompatible with reality. Need your opinion.
2016 LR4 8 speed transmission
Pan coming soon, just doing a final instructions check...
Rover Manual says:
Run it through the gears.
Put it in Neutral
Hold at 2000 rpm for at least 30 seconds.
Fine, that's easy.
And now I quote, via copy and paste:
"Move the TCS to the park position and allow the
engine to idle between 600rpm and 750 rpm.
Make sure that the transmission oil has exceeded a
temperature of 69 degrees celsius so that the thermostat
has fully opened allowing full circulation of the transmission
fluid. Allow the temperature to drop below 30 degrees
celsius before checking the transmission oil level."
Just didn't sound realistic - and it's NOT.
(and it hurts to do what you see below... ouch...)
It's 80F here today, 27C
In the garage, garage door open.
Using IID Tool
Transmission oil ain't NEVER getting to 69C at idle.
In fact, it takes, and I timed it..
28 minutes at 3,000rpm to get transmission oil temp to 69C.
(So that means I am in the vehicle gassing myself....and beating the crap out of the vehicle..for half an hour..plus the below...)
And it ain't NEVER going to cool off again either
Once it does get to 69C
Leave run at idle
Turned on garage exhaust fan, dual overhead ceiling fans and a large table fan pointed under the vehicle from the front fender
Opened hood and removed top of engine plastic cover
And wow, she is HOT!
After 15 minutes the transmission oil temperature is 72C
So it's not cooling off, it's just getting hotter.
Abandon test
And I just don't ever see it cooling off to 30C unless this is performed in Alaska in winter...
When final hot fill times comes, probably early next week,
I propose to just
start it
run the gears
hold 2000rpm for at least 30 seconds
make sure transmission is at least 30C
(per the ZF instructions in this thread several pages back 30C-50C)
do the hot fill.
And abandon the 69C paragraph.
Comments?
Thanks.
