That's a very good point - I guess I should have said that even after letting the engine warm up I still take off very slowly and let the ECU figure out when to shift.

Here's another question that a quick Google search could probably answer for me but I'd rather see what you guys have to say (go ahead BAN me) - at what temp do most of those fluids become viscous enough to lubricate efficiently?

Say the temp outside is 80*, rig is partly in the sun but hasn't been driven for 3hrs...fluid temps are probably right at 80 or maybe a little above (depending on shade, etc...).
Warming them up for a few minutes while driving slowly will raise them to what? Maybe 90-100*?
At what point do they reach their maximum viscosity?

i would guess in a short drive they would probably get up to the high 100's, their is a lot of pressure and very fast moving parts involved.

 

I let mine warm up when its below freezing, so I don't freeze!

Summer time, I jump in and go.

 

In the summer I let it idle for a few mins, usually a songs worth.

In the winter I let it idle till the fast idle drops down to 1100rpm.

Since the motor uses dissimilar metals I figured the best way to let them warm up and expand is at a slow controlled rate. In addition I never rev it past 3,000rpm till its nice and warm.

My truck doesnt like driving when its cold.

 

i wait for a few seconds (seat belt on time) always. longer when its cold out.
dont hammer it until at temp.

on my carbed cars, i defintely wait a few minutes if its hasnt run for a day or more.


on the same note i had a discussion w/a friend about a FI fuel pump.
do you let it pressurize before starting?
i never do. key in - vroooom!
