ATS transmission help

[jeep39]

More ATS

The saga carries on. It's now been just about 5 weeks and I still do not have my truck. Approximately 10 days ago Clint sent a valve body to the dealer. Don't know if he overnighted it, 2 day or 3 day but however it was sent it did not get installed until yesterday. Ground service from Colorado to VA is 5 days. Dealer says the valve body did nothing for the symptoms and the tc is still shuttering. I tried to call Clint yesterday and left a message but haven't heard back yet to see what will happen next. I wish I had my truck back. Driving a supposed to be trail only Jeep every day w/ out being able to haul, tow or move anything is really starting to suck

Clint is most likely in Vegas getting ready for the Sema show. Call ATS and ask to talk to Jeff he is in charge of the shop, explain your problems and see if you can get things moving. I think sonething is wrong with your dealer you may need to sit on him or her. Also check on towing to another nearby dealer if possible. I will probably see Clint in Vegas.

If you do see him ask him if he can call the dealer to go to the next step for resolution whether it means a tc replacement or complete transmission replacemet. Of course the dealer said they had messages in for him to call them back to go to the next step of repair.

The ATS is not designed to go that route?

The 47RE is. Lock-out O. D. when under 55MPH. Low RPM, and the torque the Cummins is capable of producing, event at 1/3 throttle is tremendous, and will kill your transmission, as you are discovering.



I don't really care if your truck is stock, or 600RWHP. Modified by ATS, DTT, Goerend, Suncoast, or whatever.

Lock out O. D. , Your trans will love you for it.



Personally, I usually shift at 2,500-3,000RPM, and don't go into O. D. under 60MPH, unless coasting, or decelerating.



That's my $. 02

Flame away.

1200rpms locked is bad on a transmission. . period... unless you can get about 140psi worth of line pressure up the torque curve to keep everything together.



nonetheless, the transmission shouldn't be shuddering at all. incorrect fluid, low fluid, high fluid, incorrect clutch packs, and incorrect converter balance/clutch balance usually contribute to a shudder.



hope you get the problem figured out and fixed!

I suggested locking out OD because on my ATS controller when I have it set real low -15mph lockup for towwing and don't shut off OD it studders and feels like stalling. When I run it with OD off until 55- 60 mph and then turn on OD it works fine. It was just a suggestion not a definate answer to his problem. It's just something that happens with those controllers.

Merrick you are exactly right. I have 195# at stall and 105# at idle and I don't shift into OD until over 60 mph with a 376 rear gear.

OTRPU, I saw your truck when I was visiting ATS last month. How many miles do you have on it. Did you have to lengthen the frame to get that sleeper unit to fit?

I purchased the Ram already extended and sleeper installed. OTR PU has over 288500 on it. Company called Roadmaster did the install. They've since folded, but sold to somebody in NC and still have the website www.roadmastercabext.com last I heard.



Cheers,

I have my 47re programmed so I can leave it in drive and let the trans decide which gear to be in.

1200 is hard on them with any load but a little throttle will quickly drop it to 3rd.



I have enjoyed re-designing mine.

Update

If this was your truck what would be the next step you would take??



The quick updated version is on 11-14 I picked up my truck after over 6 weeks out w/ a new ATS transmission and TQ. Clint and Jeff replaced the units after trying a valve body and numerous testing which still didn't do anything for the truck shuttering or slipping.



Now the bad part - same exact symptoms, same everything. What would you do or try next?? Clint suggested VP 44 issues or TPS. Problem is I'm caught in a catch 22. The dealer who installed the new unit went through anything and everything outside the transmission and tc. They say it's all good and I can't believe I have 2 bad transmission's /tc's in a row. To me it's probable but highly unlikely.



If you live in VA we have had our 1st few under 32 degree days. This AM when I went to the truck I had the same issues. Put it in drive and the truck slowly edges forward. The 1st 500 RPM over idle it just sat there and didn't move at all. Slowly creeping up to 1700 to 2000 rpm and it finally grabbed and took off. Seems to do this in the cold most often. OD shutter on lockup between 40 and 55 is still there but even worse.



Same symptoms but different transmission and tc.



Very confused and wondering if you guys have any suggestions or a Diesel shop to re check all issues outside the transmission and tc to make sure they are operating ok. Preferably w/ in a few hours of Roanoke VA.

If ATS sent another completely new trans and your truck has the exact same problems then the transmission is NOT the problem.



Personally I'd find a good diesel shop.

Yep... I'm hoping the same thing. Hopefully someone reading this can hook me up w/ a good place to take it to that is close to me.

And did you thank Clint?

 

[JTBMC]

JEEP39,

Yea first off call Clint an say thanks if you havent already. Have you checked for codes being set, 0216 VP 44 timing issues stock or not you can set trouble codes. If your truck is a late 01 its runs off a cam position sensor could you shudder be a RPM loss & gain also known as surgeing. Does your tack act eratic.

Call Doug at Advanced Diesel up in WV, and make a road trip, he has a full service shop and can help you out.

On a Dodge auto trans there is a issue with converter drain back.

It is called "morning sickness" in the trade.

What I have seen happen is the pump bushing wears out over many thousands of miles and the clearance is great enough to allow the converter to drain into the pan while sitting overnight.

I have a Dakota that does it. ( it has 288,000 miles on it ).

There are other causes. I won't even try to find them all.

Other than the following, they are all internal.

If you start the truck- put it in neutral for 60 seconds then drive does it clean it up or still slip?



Since you have a fresh trans, I would suspect a plugged cooler line. Has it been flushed?



Yes, the surging can be a fuel problem, but I don't understand how a fuel problem can cause a trans to feel like a slipping/morning sickness issue.



Anyone else have any ideas?



Just trying to help a fellow member.



Disclaimer-----I do not sell or make $$$ for a living with auto trans or diesel engines.

I have just finished replacing an injection pump, and it had 0216 as a code. It did nothing like what jeep39 is describing, when I had the problem it started with a very hard start, then eventually the truck just wouldn't start at all.



If you cycle your key 3 times your codes will appear odometer reader. So you can do a little investigating without a scanner.



Your issue doesn't sound like an injection pump problem as I think that I have had just about every one possible. I have done 6 injection pumps already.

Jeff is actually the one who decided enough is enough and sent out the new converter and transmission but yes gratitude was conveyed but the issue is still unresolved. The catch 22 for me is the shop saying there is nothing else left for them to do outside the transmission or tc. They checked every aspect of every inch of the truck w/ everything operating normally. The shop is saying it has to be back in the TC most likely. That's why Clint wanted me to bring the truck to him or another Diesel shop. I feel the same way he does... it's probable but unlikely it's in the tc or transmission.

The installing facility said they have covered every aspect outside the transmission and converter and found nothing wrong anywhere. This went on for 6 weeks. One of the 1st tests w/ the old transmission and tc in it netted bad line pressure and was resolved w/ a new valve body. After the new valve body, same thing. The issue occurs at lockup in OD from 40 to 55 mph. After that it's gone. The slippage now is even worse w/ the cooler weather. After it warms up it'll take off normally.



Do you have a number for Advanced Diesel??

Clint feels like the cooler may be plugged also. He asked me to bypass it and drive it for 20 miles or so to check it out. I don't see how it can be a fuel issue when it only happens at 40 to 55 OD lockup. The morning slippage happens only when it is cold. The 30 degrees we woke up to yesterday was real bad. I felt it go in drive but when I hit the gas it just nudged forward real slow. I never have any hard starts, never have.

 

[fox]

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.
