So just did the trans heater bypass.. that absolutely sucked!!

Firstly you need a t40 torx bit to take off the park cable bracket which is in the way of the cap to remove the trans tstat.

My bottom bolt rounded and I of course being in my apartment, didn’t have my full array of tools (tool box is in storage) so no vice grips to take the bolt out. If this happens to you, stop do no proceed! Vice grip or cut the head off of that stupid bolt and remove the cable bracket. It was a nightmare to work around. You will be able to vice grip the remainder of the bolt to get it out and replace with a new one if you have to cut it.

Ok to let’s assume you get the park cable bolts off successfully, there is minimal trans fluid that comes out, approx 2-3 shot glasses worth as others have mentioned. No noticeable change in trans performance.

The new bypass valve is easily swapped in but then comes the hard part. To get the valve and cap back in you need to depress the spring on the new valve a bit and then get the snap ring back in place securely. This is NOT fun… everything is in your way with the park cable bracket in the way (I bent and rotated it slightly).

Also if you off road your truck like i do… take 20 minutes the day before you attempt to do this and thoroughly clean the underside of your truck. Dirt WILL get in your eyes even with safety glasses on… ask me how I know.

So far 197° coolant, 203° oil and 140° trans temp, 110° ambient with AGS delete and trans heater bypass.

Another 1200 mile trip this weekend to let the cleaner work. Still tapping away.

Back from my trip to NM through the same route 87 mountain pass I usually take. Coolant never topped 200, oil never broke 220, and trans temp stayed below 150/160. A few time in NM with the temps in the 60’s (glorious break from phoenix’s 110+) the trans would be 110-130. Any thoughts if this is “too cold?” Amsoil signature atf fluid.

Also, got my first UOA back…
This is only 2500 miles when I dropped a few quarts out to add the cleaner in the engine.

High iron, and low viscosity were the two points I was curious about.

Penny for your thoughts?

No. Normal auto trans oil temp was 140-160F before these car companies started futzing with every microscopic fuel economy increase they could find.

I'd rather my transmission didn't overheat than attain another 0.0000001 mpg fuel economy. Transmissions don't support combustion - they don't need to run at elevated temperature. All that does is burn oil quicker.

140-160 is what I was expecting. Even when 60° the trans eventually got to 138-140 but there was a lot of 110-140 also at varying times, cruising etc.

metal out of tolerance can shread viscosity very easily, but that oil isnt overly sheared. Do you know the starting viscosity?

I saw that, but I posted something recently on 4 or 5 0w40's and they sheared way lower then this. Mind you I see the shear, but it could be worse. Viscosity and iron levels by themselves do not suggest fatality. It isnt a young engine, but also there isnt something that says this engine is done yet. So until that day, there is still hope for it.

Yeah I’m just trying to buy time until it’s cooler and I can swap out the internals.
