Automatic transmission shifting

The learning process never ends. Have you recently altered your driving habits?

 

Did you disconnect the battery for some reason?
Usually it wipes some learning values and this could explain the situation.

 

No,I did have the recall done for the Millimeter wave radar sensor and they needed to update the software for that. Not sure if that matters.

 

No,I drive the same.

 

That is why. No worries, give a tank or 2 to settle in.

 

Have you driven it differently than usual lately? I recently did a 5 hour round trip on Texas highways (= 85mph). The next morning the truck definitely drove a little different, but it’s getting back to its norm slowly.
<edit> I see the likely suspect reasons have now been discovered.

 

There’s a tsb for that.

 

Really? How can I find it?

 

Yeah,you think so? I hope so

 

Curious too what is it?

 

I took my Sport Taco into the dealer for the 5,000 mile service. I told the cute little "Service Adviser" the transmission shifted funny. She said "If you have time today we can apply the Transmission TBS". I said "You mean TSB?" She said "Oh, yeah!" At least she was cute!

 

That is what we experienced if we reset learning values using TechStream. You can stop by any auto-parts store and hook up OBD reader and get something like distance traveled singe DTC cleared. This will tell you that ECU learning values most likely got cleared.

 

Question for you guys,

Is it possible to overfill these transmissions or does it have something in place to spit out the extra lube in case of overfill?

I was thinking of adding a little to mine since mine is also shifting funny.

Also, this may sound dumb, but has anyone tried adding Lucas transmission conditioner to theirs? I have had great luck with their products in the past.

 

Please don't pour any Mystery Crap into your tranny under warranty.

You will have to check your fluid level with the semi-complicated method mentioned earlier.

 

Have no idea what could have changed except maybe your reading about shifting "issues". I have no complaints at all about the shifting and do not plan on getting the TSB.

 

The local dealer told me they would not apply the TSB to my 19 because it doesn’t cover the 19s

 

Do the TSB or OVTune it and call it a day.
