Transmission fluid change on my Tundra

Very nice! Stoked on the quick feedback. Mine reads at the high end of the sweet spot after a hot summer run. A little lower on cooler days.

The valve body inside the drain fluid pan works off of hydraulic pressure. The fuller level get inside all those ports/tunnels and solenoids making for better shifts pressure.

 

Rechecked again this morning after a good hour drive and its spot on. It's now sitting right in the middle of the sweet spot. Now that I think about it, the trans sometimes had a hard shift between 1st-2nd which seems to have gone away now. I always chalked it up as being a older truck with 175K so it wasn't going to be smooth as butter but it seems to be now.

I hate checking transmission fluid. It's such a pain. Why can't it be like engine oil lol?

 

Mine was the same between 1st and 2nd especially on cold days. Now its a very smooth transition regardless. Its the simple things.

 

Yup, on cold days it was worse. Maybe now it will clean it up.

 

Cold starts and the first one or two shifts its a bit tight which I guess is normal for most transmissions. After that good to go.

 

Looks like I got a ways to go after a drain and fill. Checked after trip to dump just now.

 

Looks about 1.5-2 quarts short.

 

If that’s how it reads hot, try one quart first. Mine was similar and I only needed one to bring it up to full.
