Transmission threads tend to get out of hand and I hope this one does not go there. This sight has instituted some rules regarding transmission discussions and it would be good for all of us to review them. I am posting them here as a friendly reminder and with the hope that we will do our part to keep this thread open.



Thanks

Transmission threads - new policy, please read



Enough already! None of this discussion is productive. People on both sides of this fence think that their side does no wrong and the other side does. The one thing that I am convinced of is that will NEVER change! Everyone needs to worry about their side of the fence and stay out of the others. NOTHING on this site fosters the level of discord, emotion, and anger that automatic transmission modifications do. I don't know why and don't really care - I just know that is the case.



We've tried time after time after time to get people to stick to the FACTS and keep out of personal attacks - and it comes back EVERY SINGLE time. The sponsorship issue will never go away in the minds of some. The problem on our side is what defines sponsorship? With each person you would ask there would be a different definition of it. Therefore we make no difference in the rules as they apply to people sponsored by a vendor and general users. That isn't going to change and it's pointless to debate it. We do hold vendors themselves to a higher standard and neither side likes it. Both feel that we apply the rules only to them and not the other side - which isn't the case.



The only solution I can come up with to stop this is to institute a rule that when it comes to automatic transmissions if a post is started about ATS trannies ONLY those with ATS trannies or stock can post to it. If a post is started about DTT trannies then ONLY those with DTT trannies or stock can post to it. Likewise with BD, Suncoast, Goerend, or others. I find it sad that it has to come to this but I don't see any other workable option based on the track record. These battles have been hashed out over and over again and nothing has come out of them other than people being ****** off and driving users away from the site. From here on out we will be deleting posts based on this policy. If you see a post that falls under this policy DO NOT fire back at that person - simply report the post and it will be taken care of.



If a post is asking a general transmission question you can post how your transmission modification works - but DON'T discuss the other side AT ALL. Posts WILL be deleted with no notice that do not meet this standard.



I'm sorry it has to come to this.

I think some non brand specific advide could be tolerated. After all, he didn't solicit the guys business. Seems like a little sound advice from an outside party.



I don't believe censorship will help get this guy going. He needs all the help he can get. After all, he's paid for a professional to diagnose and repair his truck. He's had some problems. Maybe "the other guys" can contribute?



Take it or leave it. Your choice.

Have you ever ridden in a vehicle equipped with a manual transmission when the driver needed to downshift and wouldn't do it. The vehicle bucks and jerks. If the torque converter is locked and the transmission is in OD (high gear) the same thing will happen with an automatic transmission. When the ground speed is to low for that gear a bucking or shuddering will happen. Try setting your torque converter to lock at 40 mph and lock out your over-drive below 50 mph. If the condition is still there let us know with another post. The process of elimination is slow especially when it’s being done long distance.

Re: transmission

You are right you did say the same thing. From the quote below taken from page three, I just thought a reminder would help. I think a good deal of the problem is that jeep is letting the truck go into OD to soon. Locking the TC at 40 mph is not the problem.

After the new valve body, same thing. The issue occurs at lockup in OD from 40 to 55 mph. After that it's gone. ... .

In accordance with the guidelines I have deleted a number of posts from this thread. I did forward the advice from Stephan to jeep39 through a private message. As stated in the guidelines if a post is regarding a specific companies transmission then only the owners of that companies transmission or stock can post to it. If someone else wishes to impart information to an individual it should be done through private messages or an email. It's very unfortunate that it had to come to this to keep peace on the site but we tried everything under the sun up to this point and this latest change to the policy has kept the peace for over 7 months.

I've had to delete a couple more posts on this thread. Let me reiterate the part of the guideline that is the issue here:



The only solution I can come up with to stop this is to institute a rule that when it comes to automatic transmissions if a post is started about ATS trannies ONLY those with ATS trannies or stock can post to it. If a post is started about DTT trannies then ONLY those with DTT trannies or stock can post to it. Likewise with BD, Suncoast, Goerend, or others.



If you are the owner of or affiliated with an automatic transmission vendor other than ATS please contact Jeep39 through a private message or email.

What it the line pressure when you first start the truck cold??

I would also watch this same pressure for the lock-up event to see if it has enough to hold it.



Get the readings and get back to us.



I hope the pressure tap has been out before and it has a guage on it right now.



My friend had a 01 fail---it was slipping---- and asked me to get involved.

After the dealer and a trans shop both diagnosed it as a rebuild time, I crawled under it to put a guage on it and try to get some experience, and found the pressure plug had never been touched. !!!!!



How does anyone know what is going on without test equipment???



Anyway, get the readings from you trans tech and get back to us.

You need you truck back.



I'm not sure of ATS's installing procedures on a new setup... I don't know if they want tests done after the new stuff goes in to make sure it's ok. Based on the talk I had w/ the tech after the new stuff went in it was just a test drive or several test drives.

Steve - if this thread is causing stupid things to happen w/ folks just go ahead and delete it. I got e mail like mad when I started it telling me I was new and didn't know some folks got bent out of shape on this forum all the time. I'll keep the group posted on the outcome but if this is trouble just get rid of it.

I have owned other Dodge Diesels and from what I can remember, they would unlock the converter or downshift before the shuttering started. This one slips when I try to take off and then shutters when lockup happens between 40 and about 55.





When the ground speed is to low for that gear a bucking or shuddering will happen. Try setting your torque converter to lock at 40 mph and lock out your over-drive below 50 mph.



And how might I do that : )

You may want to read this thread. It has to do with the APPS and it describes symptoms similar to some you mentioned.

Yep... that was one of the many things that were gone over. It was checked out ok...



As of today it looks like I'm heading back to the installing dealer to start the duplication process all over again. This time w/ me driving the truck even though he duplicated the slippage and shutter w/ out me in it the 1st time. I'm sure this will end up being something silly and I hope to laugh it off after it's fixed.

transmission

Thought I would put up a note to keep those interested in it informed... The truck has had the same symptoms as the 1st go round and nothing has changed. It still has OD shutter up to 60 mph and now has started a few new things it never did before. One of which being after well into the warm up cycle, the tc will hold unlocked at times up to 50 mph. This is even after driving it all day. This is something new that it never did before. And when it does go ahead and lock the converter up, it struggles to do so. The truck has actually started to buck a little when this happens. ATS doesn't want the truck back to the shop that did the work in Richmond. I found a local place to look at it and Clint gave the OK but they are telling me upwards of 1,000. 00 or better to get it done and there is a possibility that the transmission and or TC may be bad and my truck will be stuck at a non ATS dealer. There are no ATS dealers in my area. I thought it may be worth the 3 or 400 more I may have to pay to get ALL the outside things checked and re checked that may be making the transmission/tc act the way it does but the initial test drive by another tech says it's in the transmission/tc. What a mess... .
 
Describe what its doing now, exactly. I will try to help.

I know it's a long thread but I will be as brief as possible but 1st, thanks for the attempt to give me some ideas.



At about 140,000 miles, the transmission and tc were replaced w/ ATS units by HAAS in Michigan. The 3500 was used for picking up cars w/ a 5th wheel at auction in PA and hauled back to Detroit. We did that for over 6 months putting just over 45 K on it in that time frame. One day she started to shutter in overdrive. Slightly w/ load then big time unloaded. When this happened, I had the truck here in VA. Clint directed me to the closest dealer for ATS and I took it to them... about 185 miles away. They had the truck for 6 weeks. Eventually, Clint found bad line presseres somewhere in the truck and decided a replacement valve body would fix her up. That did nothing for the truck at all. Clint had the ATS dealer check all outside things that it coud be also. They checked, re checked then checked again. It was decided a new transmission and tc would fix it now w/ out any more trouble. The new units went in, I picked up the truck. No changes... all symptoms came right back w/ no difference. That definately pointed the finger back to the "outside" things that control the transmission and tc and I was supposed to take the truck back to the installing dealer to have them re checked again. Two weeks ago I got a call from Clint... . the new valve body that was sent to the installing dealer trying to get the line pressure issue resolved disappeared. The one that got back was not one of their valve body's. I don't know what he found out about that but it was a real fishy situation. Needless to say, he did not want the truck back to the dealer up the road. So here I am kind of stuck...



Truck profile



2001 3500 DRW w/ ATS tc and transmission. Less than 4 K miles on the new units. truck has 190 K on it.





Lockup speed



TC locks up at 35 to 40 in OD then startes to shutter. Stops shuttering at about 60 mph.









Motor at operating temp



Yes... actually acts normal during the warm up cycle. The tc doesn't lock up and no shutter but as soon as it warms up and the od kicks in... shutter.





does it happen at a certain throtle postion.



Any position, any time up to 60 mph.





Anything and everything you can think of.
