just got mine done today felt fine on way home will test drive more and report back

 

How long did the process take?

 

Went to Dealer today to have the tsb-0062-18 applied. On the pdf file it says 18’s are applicable. Even asked if other members with 18’s had it done and several confirmed. Dealer applied tsb-0058-18 wich according to the pdf in this thread does not list 18’ models applicable.Waiting to hear back from dealer.

 

They are the same. You can only apply the latest update available on TechStream.

 

had mine done 2 weeks ago, posted my results, in the other 5 threads, on the same subject

 

So the 0058-18 and the 0062-18 are the same? The pdf showed here doesn’t say applicable to ‘18s but the pdf my dealer showed me for the 0058-18 says ‘18s. Going back and forth with them now so want to make sure my facts are straight as I used this forum as reference.

 

So this is the same tsb number in this thread and it’s the copy my dealer gave me... why does this one have the ‘18 models and the one originally posted doesn’t. Going back and forth with dealer. Just want to get this resolved and have some piece of mind.

 

Cause it clearly says Rev 1 in which they made a revision to this original from July 9 on July 31st to include the MY18. Relax bud, you're good.

 

I see that now. Feel stupid I over looked it. Thanks for all the info

 

Just dropped mine off

 

Didn't notice anything after having mine done. Anything that seemed different in the way it drove I'm sure was placebo.

...but then again my dealership could be full of shit and have never done the update.

 

U can check and see if they did it with a obd2 scan tool. I had my 18 done last week. It showed both calibrations when I picked it up. One shows ecu engine update for 62 and 58 shows trans update.

 

80 miles on my update. Half highway half backroads and town driving. Shifts are noticeably smoother up and down. The same hills I drive everyday, gears hold and feel more responsive. On the highway it wasnt constantly hunting. Got slightly better gas mileage. Definitely not placebo for my case.

 

Mine either. I just took a 500 mile road trip. It was like night and day to the old tune. Shifted great. It actually used 5th gear and didn't race to 6th gear like before. Plus I got 24.5 Miles to the gallon with 5 people in the truck and 500 lbs of shit in the bed.

 

Found this in the TSB-0062-18 thread

 

Def noticeable. The shifting is much smoother and less flooring needed. You could feel the diffrence as soon as you touch the pedal. I can only wait and see once I hook up my trailer and quads.

 

Have about 400 miles on mine. Better shifting from stop to start but still getting stuck gearing between 5th/6th with high rpm. Not a huge difference but helps.
