Gas mileage decrease after TSB-00-77

[B-RI]

After the TSB-00-77 update my gas mileage has only been 14-15 mpg. How about everyone else.

Is that the transmission update ?

 

[B-RI]

Yes

 

[warmongoose]

Does it get better after a few tanks of gas to relearn the shift points?

 

[AdventureTaco203]

No mpg changes after tsb for me. 2016 crew cab trd offroad. Avg 18.5 before and 18.5 after tsb.

My mpg is beginning to increase after I got the tsb three weeks ago.

The TSB did not affect my gas mileage. Nor did it fix any of the transmission problems I was having?

Is a new Transmission update for 2016 Tacoma... the TC1601, get it done this morning.
The TSB 0077-16 didn't work for me.

Yes sir!!

I believe they have more than 1 tranny update. After I got mines, I'm noticing a 1 mpg increase. Update fixed the gear hunting and R to D delay.

I've only had one done and I've definitely noticed decreased MPG. I also noticed now every so often I have a very rough downshift when coming to stops. Anyone else have this? I'll be sure to ask for the newest TSB when my next service comes up.

I've had the hard downshift when stopping since I got my truck. It seems to only happen going from second to first, and it causes the brakes to feel inconsistent. Sometimes I think it may all be due to axle wrap though.
