Love this thread! Thanks for the knowledge/help!

Can someone help me understand what is going on in this thread? I just got my 3865 today and I have not installed it yet. Do I have the ability to do the tranny tuning? If so I noticed one file for an 04 in the link on the first page, I assume that would be the one I need to copy? Is that what you do just plug in the tuner and set all the TP% values like the ones on the excel spreadsheets? This is the first time I've ever messed with a handheld tuner so I'm really lost.

First timer on forums... I just got the tranmission tune, and man it's confusing. I decided to not even try to understand what it does and decided to upload one of the current ones posted here. I went with the myoung one that sets the TM at 7.2, My problem is that the numbers don't add up exactly. The 1 up match up but that's it. The one thing I did was set the TM t 8 all around instead of 7.2. Is that ? Any help would be nice.. Oh, I did put the numbers as close as possible to the one on the spread sheet and drove it, it drove fine. Your thoughts

first off GREAT thread and a BIG thanks to Sil,

does anybody have a SS for a 4th gen 4.7?

Starting to finally mess around with this now but I have a few questions that can hopefully be answered. For the OD off settings, does this apply for when your in tow/haul or just in manual selection? Also speaking of towing, I tow 8k pounds from time to time and are these shift schedules safe for towing? I am mainly looking at JJ's or myoung's v3 uploaded schedules, although JJ does not have any for OD off. Oh and 2010 hemi here

Was hoping I could get some input on my schedule for our 08 Jeep GC...it's much better than stock, but just like stock, I can't get it to stop skipping 3rd gear in most situations. Holds first and second just like I want, then goes straight to fourth and holds that just like I want until fifth but in normal acceleration it skips third.

I've got an 02 Dakota running a Jeep TCM (to allow 5th gear) and it clearly uses 3rd gear. I'm very familiar with the transmission but stumped as to why the Jeep does this.

If I force 3rd gear with the auto stick it does just fine and provides a nice slight RPM drop.

My graphs look good to me and the shifts are good though I've only been able to drive and adjust a few times.

Thanks! Sure wish some of the people on JeepForum knew anything about anything...all they seem to know is how to plastidip and put on a 'sweet' budget lift.

Graph looks ok. Can you post up all your throttle percentages, so we can see where you have your shifts set?

Never done a Jeep, so maybe Scott and I can collaborate on this one.

caulk04 · Mar 28, 2013

I can do screen shots again when I get home, but I'm more than happy to email you the excel file if you want to put it in that database.

On a side note, is it typical to see a decrease in fuel economy with the 87 tune? Again, I don't get to drive it much (wife's DD, I drive on the weekends) but the EVIC has shown ~1mpg drop since I put the tune on it.

SilsHemi · Mar 28, 2013

Not typical to see a decrease in mileage. Give the tune some time to settle in and see if it recovers.

I'll PM you my e-mail addy.

Data screenshots for anyone interested...

The mph numbers are rounded off because I did a cursory tune in the Jeep, then adjusted with the tables on the PC and picked the closest number once back in the Jeep.

SilsHemi · Mar 28, 2013

New schedule for your Jeep sent. Thanks to Scott! Let us know how it goes.

caulk04 · Mar 29, 2013

Good stuff fella's! It's great to get a little assistance from a total stranger, especially when you're a new guy to a forum.

Hopefully my last revision to the schedule will make it to the database and help someone else in the future.

Djcusaf17 · May 14, 2013

Well, I'm finally getting back into the swing of things now that school has died down a bit! So I started off with using the 2008 4.7L spreadsheet and adjust from there . . . no good haha I have to start from scratch since I run 4.56 gears and definitely running a bit high on the RPM before the shift and my Stock MPH settings were a LOT lower than the said spreadsheet. I really should have gotten my truck flashed at the dealership after going from 3.21 to 4.56 gears but I didn't want to hassle with them since I already had a tuner anyways.

Should be fun!

P.S.
Any way to view the schedules from the SC tunes? I am going to guess that's a no. Just thought I'd ask anyways.

Aside from the custom shift points, I found previously that 8% TM all around works great for me for daily driving.

2005 ram 1500 shift issue

So I downloaded the advanced trans tuning and loaded based on the table for an 2005 ram with a 4.7 Liter and when WOT at 75 or so will shift to 4 and then briefly shift back down to 3 and then back to 4 and pull to 105mph. What do I need to modify in the tune to avoid this issue? Has anyone else had a simular issue?

Currently went back to SC shift tables with 1-2 WOT shift RPM to 5400 and TM changed.

Bringing up an old post, but been searching for transmission tunings and thought I had found the honey hole till I found out there's no trans tuning for a 4.7 2009 rwd 3.55 ram 1500... :-( thought about using the 2010 but didn't even look at gearing ratio or anything like that. What r my options?

bloombloom88 · Oct 31, 2014

Which tuner are you using?

RNTbone · Nov 1, 2014
