Hello,
My only complaint is about the newer Toyota transmission is No Dip Stick.
I like to change the oil in the pan every 30000 miles. Easy job 4 qts. Not any more No Dip Stick.
Now, locate fill plug, have IR temperature monitor, drain pan, reinstall plug, add oil till it pours out tranny tube, have your Allen key ready, start vehicle, monitor tranny temp, at 115 tighten plug tube. It was easy now it's a pain.
Good luck
