Great post! This should be made a sticky in my opinion.....and think many others would agree.

 

its stuck:thumb:

 

Thanks Dave!

I assume the relearn for a H&S is the same as the spartan correct?

 

I can't answer that, I have only ran a spartan, but I honestly can't see why it wouldn't work. I posted this because there is alot of guys asking what tranny relearn is, and I figured this would help.

 

Once your download is complete your transmission will be ready to re-learn. It is recommended to perform the re-learn process while in the "HOT" setting on the Black Maxx Tuner.

During this transmission re-learn process you may experience "harsh" shifting, "missed" shifts, or erratic results. Continue the process, this is normal.

Drive for a series of three runs:

1. 0-60MPH @ 1/4 throttle position, then slow down and come to a stop

2. 0-60MPH @ 1/2 throttle position, then slow down and come to a stop

3. 0-80MPH @ wide open throttle, then slow down and come to a stop

 

this relearn, is it only if you have a tuner. If you don't have a tuner and want to get rid of the bad shifts, can you do the same??

 

My truck did the exact samething, with the revving then droppin in gear, I have a KEM 210 with livewire, would I need to reload it the tune and do this or what?

 

I am having the same slamming problem, but with an SCT. Please someone tell me how to relearn my tranny with this tuner!

 

A similar or the same trans relearn should do the trick. Also, have you tried adding some tranny fluid? If neither a relearn or added fluid help, it's just something you may have to deal with.

 

i am worried about damaging the transmission, thius cant be a good thing can it?

 

I have had it happen many times with no damage to my transmission. The issue doesn't seem to be directly related to tuning because stock trucks have been known to do it. It's a 5R110W issue that has been enhanced with tuning. Just try what I said above, and go from there. Let us know what happens.

1. Trans relearn
2. If that doesn't help, add about a 1/2 quart of transmission fluid.

Stupid question. If you're running a Spartan, is that the Spartan or stock TCM? thanks, I had a brain fart lol

 

Unless you purchased a Spartan TCM, you have a stock TCM.

 

Does the relearn have to be done on the tune you plan on running or can it be done on a lower hp tune to make it easier on the truck and tires?

 

Each tune has its own transmission file (at least each Spartan tune does), which means that every tune is different. You can't load a 150 tune, do a transmission relearn, and then load up the 310 tune. It doesn't work like that. Only the bigger tunes need a transmission relearn anyway. The 210 Tow, 250, 275, 300, 310, and 350 tunes all need transmission relearns of some kind. The regular 210 and lower tunes do not. They shift very similar to stock.

 

How long after you load the tune do you have to do the trans re-learn?

 

Doesn't really matter. Sooner the better if you like your shifts to be more consistent quicker. The transmission will learn whatever driving habits you have anyway. So if you load up a tune and wait 300 miles to do the transmission relearn, the transmission is going to shift according to how you drove those first 300 miles.

Just for clarification. I would have to do this with 4WD engaged. I tried this once w/o 4wd on and the TC kept kicking in. Turning off the T/C really hurts your acceleration :rofl:
Does this cause any issue w/ the relearn process?

Nope. Here is the relearn (or close to it) that I do when I load a tune. It might be more appealing to most of you:

Load the tune. Once complete, take the truck for a drive. Drive through the gears easy a few times, stop sign to stop sign type driving (I live in a big neighborhood). I get out of the neighborhood, and make a 30 minute loop through the city/county I live in. We have a major U.S. highway and a major U.S. interstate running through here, so I have plenty of road to choose from. When I get to a red light or a stop sign, I run the truck at 1/2-3/4 throttle through the gears once I start going again. I do this as much as possible. The more 3/4 throttle pulls through the gears, the better. If you do enough, there really is no need for any full throttle pulls. I then get out on the interstate, going through the gears pretty hard up the on ramp. Before I merge on the interstate, I slow down to about 50-55 MPH and roll into the throttle hard. This allows for a good solid downshift and then a final shift in to OD with the converter locked. I try to imitate several different transmission shift patterns that I experience or use on a daily basis. I try to imitate them more than once.....actually as much as I can. The more you do, the better. After about 30 minutes, I am back in the neighborhood going through the stop signs again, easing through the gears. Everything shifts great from there.

It's ideal to do a relearn pretty often. After a few weeks on a tune (if you don't change very often), the shifts can get sloppy. To combat this, all you need to do is a quick relearn. No need in reloading the tune.

tried all of these things and no matter what the 250 and 275 tune is just violent feels like my trannys gunna fall out then i put it on the 210 tune and this thing drives incredible

 

Do you have the latest tuning files? They were updated in May. The shifts were softened considerably and will definitely not be softened more.

 

i just bought tuner last week so i had to re-license it and re download tunes of spartan site last week

 

You have the new tunes then. You have to give them time to learn. They don't shift smooth right away. The 210 tune shifts similar to stock, therefore it is smooth all the time. The 250 and 275 tunes do not because they are race tunes. They will smooth out over time.

 

no need to do any of that kinda stuff with the H&S. The instructions say too but i have never had to "perform" any kind of "re-learn" anything with H&S, just load the tunes and drive the truck. Nevermind haveing to add fluid and all that sounds like a lot of work. The transmission will shift pretty firm at first but within 20 miles or so of normal driving and everything shifts like it should. Plus I run KEM tunes with a mini maxx and right from the start the shift quality is excellent without any "training". Plus if you actually follow the instructions of the "relearn" process pound for pound you would need to find the nearest Airforce base to perform them and rent out their landing strip!! No Thanks.

 

So far i know put 2000 miles on the 275 tune and i hate it it has a load of power but the tranny hasnt learned anything and theres no way this tune is at all good for my truck :dunno:

 

Not sure what's up. There are people that have ran the 275 tune for 80,000-100,000 miles with no issues at all. If you are expecting the tune to shift like stock, that isn't going to happen. Your transmission wouldn't last a week.

 

im excpecting it to shift similar to the 210 maybe a little harsher but when i punchit at 30 and it goes and while im on the throttle it shifts up twice then goes back down 1 it just doesnt make sense like its just incredibly sloppy

 

If you want that big of a tune to shift that smooth, I suggest investing in a SunCoast. I don't hear complaints like this from other customers that are running this tune. Many of our customers daily drive this tune with zero complaints.

 

I'm on SunCoast #1 with 38,000 miles on the unit, 75+ passes at the track, and no telling how many 3/4-WOT pulls testing tunes. My transmission shifts like butter. Spartan TCM with SunCoast transmission files. Couldn't get any better in my opinion.

 

Do I need to retune my truck, updates? My tunes are early ones for the 310 and TCM? I have broken: Torque Converter X 1, Billet input shafts X2, new clutches X 3 replaced every time the trans has been apart.... I run the 310 tune as my daily driver. It shifts SO hard under light throttle or coasting. WOT perfect. I still do not understand the gear hang-up that I get before the transmission breaks (this is where I am currently).

How can I get replacement tune files? My SD cards are lost, with the exception of the 310 TCM tune..... including my stock file.

Thanks!

Mike

 

We've had SunCoast tunes for the TCM for over a year now. You definitely need to update. You'll have to call the office tomorrow and talk with Mick to update. It's going to be extensive because you'll have to update your DashDAQ software and tuning files. Your behind the times my friend. If you had updated months ago, you would have never had these issues.

 

THANK YOU!!!! I will call Mick tomorrow!
