Watching this one.....

I have the 4-5 chirp on my '13 that has showed up. I am thinking about going back to stock and heading in to have it looked at. Others have said that the 4 and 5 clutch packs are probably burnt. I am currently leaning towards a replacement from Midwest but I am waiting to see what really happens. And I don't want to drop the $7K unless I have too. Currently running Gearhead on the XRT.

Hope you get this figured out and let the rest of us know how it goes.

 

Ok, thanks very much. Appreciate the info greatly. Is it easier to take one apart now and just fix the 3-4 clutches or will the price difference be negligible between that and an entire rebuilt/beef-up?

I heard these trans were plenty strong enough to handle far above stock power but im positive it was slipping when i used the stock trans tune with the race engine tune so im sure thats what did the damange. I felt it probably 3-4 times before i decided it was worse than the clunking and banging and change it back.

The race trans tune did the TWANG sound i think before all this as well though under WOT on performance power setting. Is there springs? or bands inside these transmissions? thats what it sounds like kinda i think, maybe have to take it to a trans shop and have them ride with and listen to identify it, but its a sound ive never heard come from any vehicle before and ive driven lots of them, lol!

Do they have some sort of protect/limp mode on them? Still not sure why it failed completely once and then was back to working after restarting the motor on the truck. Unsure what caused this and/or if its likely to happen again or eventually just fail completely but other than the odd noise between 3-4 shift its been fine every since with zero slipping even when pulling 9000+ pounds so I was hoping for more enlightenment on this freak occurrence if you can please.

I dont expect an exact diagnosis with this limited into and poor discription of the sound but i doubt theres many noises a transmission would make and thought someone with more knowledge of the inner workings would have a rough idea of whats causing the noise and cost/time to fix it, i havent a clue whats inside these but ive heard some have bands of some sort, thing metal bands or some type of spring might make the type of noise im hearing im guessing, but i could be way off. Maybe once you gotta even touch it it doesnt really matter, its 7K, or maybe you only gotta go so deep and its only 2K is what im wondering basically.

If you did tunes and not actually tearing them apart and rebuilding them then you may not know either, but i was just kinda curious as I have it deleted and wondered if it would be worth the hassle to put it back together and try to take it in for warranty or pay out of pocket for a better/stronger one or beef it up or whatever so this doesnt happen again. My dealer is pretty good and i think they may cover it if they could, not sure how it works but they dont make a stink for other warranty items on deleted trucks anyway like some dealers do. I think it wouldve probably been just fine if i hadnt used the wrong trans tune with the wrong engine tune however, Had no clue about that, now i do, thanks. Mights have cost me $7000 to learn it though,

 

odd, my 4-5 is smooth as a babies ***, but stock before i messed with it i had a 2-3 weirdness, banging or rougher anyway, tested my M 5-6 after i read this and its just as fast as the rest, wasnt pulling nothing at the time though, yours do it empty? mines a 13.

 

What power setting do you tow with??

 

NOBODY that knows what they are doing would completely tear down a trans and only repair one clutch.

Ignoring the fraudulent aspect of this, I have one question. What warranty? You don't have a warranty from Ford. There is software that can and did detect that the engine was making more power than stock. You can't clear this code, and it voided any engine or transmission warranty you thought you had. If the dealer warranties the trans that was damaged from aftermarket tuning it's on them. If they try to get Ford to cover it they could lose their franchise.

Maybe you bought an aftermarket warranty that will cover owner abuse. When I owned an independent repair shop I dealt with many aftermarket warranty companies. Most of them would only guarantee that they'd take your money. Trying to get them to pay for repairs that their paperwork said was covered was like trying to pull teeth

 

Stock power setting

 

From what I've heard most dealers are covering most things on deleted trucks anyway unless it's blatant abuse like pushing stock turbo to 40psi boost or something well outside it's ability, which they might consider this, I don't know, this is the first Ford I ever broke, usually they last forever, lol! I've not heard anyone else have trans issues with a tune unless they go past 600 horse and I'm below that.

Interestingly I've been driving normal and the twang went away. Still twangs when I hammer it on stock power though, haven't put any higher lately. I don't understand that twang.

 

Maybe time for a YouTube video (audio) of this "Twang"... The only time I have heard an automatic make any sharp noises is when there were parts already in the process of breaking. This like sprags and clutches in the process of disintegrating... Frankly, I would treat that truck really nice until you have an alternative course of action...

 

yea ive been pretty nice to to it lately and it went away unless i stomp on it. For a while it was even doing it when driving normal, may have to try to get audio but it might not pick it up. Might not even be the trans, i dont know. only happens tween 3-4 though so i thought it was.

 

I don't know who you bought your tunes from but I would be calling them and asking for some support. Any tuner company worth its salt should help you out. Good luck.

 

I got them from SPE, but they are in PA and im in ND, so not much help to be had really. ive asked them a million questions which they answered, I do not think their trans tune is faulty but i never really got an answer to whether the clunk/bang is acceptable or not, but id guess its much preferable to slipping. can you even get a smooth shift when your putting aprox 550 ponies to it at WOT with well over 1000 foot pounds of torque? fack if i know, and now one here is saying yet, lol

 

UPDATE:

I guess i was mistaken, the transmission never really went to limp mode or whatever, apparently i shifted too fast and it quit responding. it happened again and i shifted to park and then it started working normally again without an engine restart. either a linkage problem or shifting too fast issue. its not slipping at all, just the twang sound betweeen 3-4 gear shift. been busy working and havent had time to get to a tranny shop to see what they think it is. works fine if i drive normal, only makes the sound if i drive it hard. Doesnt slip and pulls trailers just fine.
