Folks:
I bought a 2012 used Tundra crewmax 5.7 (~25,000 kms) a couple months ago and I find the transmission downshifting/engine braking very annoying.
I have been thinking that there is something wrong with it but I am not sure. For the first few miles, it behaves as I would expect....ie....when you let go the accelerator it "free wheels". However, after the transmission gets "warmed up", once you take your foot off the accelerator its very likely to "engine brake/downshift". Sometimes I find it hard to tell if it has downshifted or if its just holding a lower gear longer than I think it should. And this is on level ground....not on a decline after a brake tap....
Does anyone have any ideas? Is this normal? Is there anything in the drivetrain or transmission that could otherwise cause this behaviour? Transmission fluid low etc??? Something in transfer case, differential...etc. etc...
I had the ECU reset but this didnt seem to make any difference. I only have a few days of bumper to bumper warranty remaining so if there is something wrong I would like to get it addressed.
What puzzles me most is that when its cold, it behaves as expected. It will "freewheel" when cold but once its warm, most times when you release accellerator it will downshift/and or engine brake.....like there is always resistance. This resistance must impact fuel economy????
Thanks for any feedback/advice.
