Shift flare / tranny slipping?

I called my dealer last night they want the truck to sit overnight at their lot so they can replicate the flair upon cold star up. I will be dropping off Monday night so hopefully will hear back Tuesday at some point.

Also to add info to this thread I did some highway driving and noticed the trans grabbing for gears very erratically.

Stupid question here. Is this TSB only in relation to 16 models or will my 17 fall under it as well?

 

It covers 16 and 17.

 

The trans will still want to upshift for fuel economy

 

Ok I just felt like it was doing it more often then it should had. Definitely preformes differently then my 13 did at highway speeds.
Thank you for the input!

 

Excellent. We look forward to your updates.

 

It's different because you now have a 6 speed instead of a 5 speed. It will try to access that additional gear if in Drive or S6 to keep rpms as low as it can as it tries to conserve fuel.

 

What jsinnard said. It is going to feel WAY different than your 13. There is a learning curve to this thing including effective use of S mode and ECT.

Yeah it's a totally different beast. I Actually need to get use to it more myself. Thanks for the information guys, it's much appreciated.

 

It should be of some consolation that almost every make of car including luxury vehicles are experiencing shift flare on some of their vehicles. I have come to the conclusion that the newer trannies (hardware and software) are too complex for their own good.

This is part of the reason I have no interest in getting the TSB. Why mess with it.

 

My BMW does not do it. our 2016 4runner performs perfectly and has balls

 

Not saying it is normal or should be considered normal, just that almost every make (including BMW) has had it on some of their newer trans.

 

I've never had this problem on dozens and dozens of vehicles I've driven or owned including rental cars of many makes and models over 20 years and I traveled quite often for work

 

Well Saturday and Sunday morning I took the truck out and didn't have any flare. I will keep it in the back of my head but I think it's fixed.

Thanks guys!

 

When you Brought your truck in, did the dealer have to replicate the flare before performing the TSB?

 

Nah - I had taken a video but they just glanced at my phone and didn't even watch it. But they said they would try the TSB and if it doesn't fix it they would dig into it more for me.

 

Ok, maybe I'll do the same and snap a video of it as well. I highly doubt that they are going to be able to replicate it. Due to it not happening but only when I leave work everyday, and also rarely in the morning. Just curious, does it take long to do?

 

Justin, Doing the TSB only takes a few minutes. It's a computer update.

Ok, I figured it wouldn't take long. Thanks

 

got the TSB done in July, then I started noticing the shift flare when the weather got cold (didn't have it last winter prior to the TSB). I just got the new updated TSB done this morning. Hoping it fixes the problem.
