Here we go again on the transmisshin

[Hot Shot]

O. K. >>>>>

Still have some slippage. I have had the BD med. stall torque converter(I guess that's what it is) Pressure lock, and BD valvebody installed. Pressure is just over 120psi.

With the VA plugged in the transmission slips ever so slighltly with just my empty trailer.
Unplug the VA and it will not do it.

Drop my trailer and plug in the VA and it runs like a champ.

What do I need to do now go inside the transmission and replace all the clutches and bands and all that stuff. What gets me is when I don't have my trailer hooked up you can't tell nothings wrong. I've spent $1800 and I have not accomplished a damb thing. #ad

What is slipping? Is it the T. C. clutch, or the clutches in the transmission? At what rpm & boost do you see this slippage? In what gear? And could you phone or post your pressure readings. Thanks,Piers

[B.G. Smith]

Hot Shot, I think the TC slipping is worsened by the fact that the "box" causes the engine to run at needed speed with a lot less movement of the accelerator pedal, this results in very little movement of the throttle valve on the transmission and results in low pressure and TC slippage. I wonder if your pressure lock is really working? I also wonder if the "box" is messing with the PCM as well as the ECM.

Slippage only occurs in OD at highway speeds 70-75. There is no slippage in lower gears and no slippage under acceleration. It will occur intermittently. Line pressure at 1800rpm seems to be about 120-122 psi.
I can run in 3rd all day pulling my trailer-loaded or empty- and there is no slippage, but maintaining highway speeds at 2800rpm and 7 mpg is not going to cut it. I can drive thru town at 35mph and no slippage.
Only in OD at highway speeds with the rpm 1800 or higher .

Sincerely
Slipping in the South.

Evan,
This sounds like a scam to me, i sure hope you and the POWER SHOP arent involved in using this type of scare tactics as a way to sell products to unsuspecting customers.

Hot Shot, same symtoms as you. Started when I would pull a "low profile" 5ver with the VA CPC. Added the BD/VB and problem went away. Went to a "higher profile" 5ver and problem came back. Take VA CPC off and problem goes away. Guess the position of the TPS does make a difference.

Thought about the Pressure-Loc, but I feel the more enhancements added to the transmission, the more prone it is to failure. Don't like the thought of that when running out in the tullies somewhere on vacation.

The solution to my problem (not for everyone) was to go back to a manual transmission. #ad
You would think after running diesels in these trucks for over the last how many years they(auto makers) would of designed a transmission that would hold up against the pounding of a diesel. #ad


Good luck on your dilema #ad

Hot Shot it sounds like your overdrive clutch is slipping. Please phone Pat at 1-800-887-5030 he would like to get a few more details from you if possible. I should have asked what oil are you using? Here is a quote from a famous person on that matter #ad


There are two different terms used Torque Converter shudder and Torque Converter slippage.

Torque Converter shudder usually manifests itself at low rpms when the clutch is trying to grab and there is not enough centrifugal force within the tc to hold properly. The damper springs are bouncing and bottoming out (loading and unloading).

The symptoms are similar to if a standard transmission was in 5th gear and should be in 3rd gear as dictated by vehicle speed, or for those of you that have an exhaust brake with your automatics and are in 4th gear locked up when coming to a stop, that shudder that you feel, it’s like the wrong gear selection.

Torque Converter clutch slippage is when the clutch is actually slipping and the engine rpms climbing and vehicle speed remaining the same.

Per our phone discussion and your symptoms as described I believe we are dealing with a torque converter shudder.

The other thing that can cause a tc shudder is the lack of fluid co-efficient with the clutch lining.
As you indicated you are using Dextron 111. Dextron 111 oil is the most resistant to slippage, but is more prone to cause tc shudder in Chrysler transmissions. We have an additive on the way to you . This is what I use in my personal truck. Gary this is similar to what you experienced when you changed your rear end oil
and had to add an additive to eliminate the rear end clutch chatter, this is what I mean by lack of co-efficiency between fluid and clutch material.

The lack of centrifugal force within the tc (ie-low rpms ) was a difficult thing to over come especially given the gear ratio combination of the Chrysler 47RH & 47RE transmissions.

This was the reason we developed the 2nd gear loc up program.
We set up an electronic interphase between engine and transmission to allow 2nd gear lock up between those difficult speeds where you are basically lugging the engine in 3rd gear. This device allows the driver to manually shift into second gear and engage lockup. This gives you a nice gear combination between 15-40 mph. This is for light to moderate driving conditions ie) off road use, or in heavy traffic when 3rd gear is not practical.

For those of you that are hot rodders, you guys can just forget about this system.
This system is designed to dis-engage under heavy throttle.
It is adjustable for rear-end ratio, horsepower, and weight and can be used for exhaust brake applications.

I believe there is also a re-flash available for the PCM to delay the shift points and tc lock up, I am at home right now and don’t have the number with me.
I will post it tomorrow for you.

Piers,
You probably know more than most, so I would like to know what the 'shudder' is while accelerating when my auto-trans shifts into 3rd gear but doesn't seem to slip, and then shifts into 4th and finally overdrive with no other symptoms.
I am currently "testing" PE's EZ box. #ad
I am also "testing" the boost elbow increasing my boost to about 25lbs.
Thanks, Bob

You are probably experiancing the torque converter shuddering as it locks in 3rd gear. If you have the overdrive locked out & then turn it on the TC will unlock then it will then shift into overdrive & then lockup again once you're in overdrive. What rpm & boost do you feel the shudder occur?

[RobbyRam]

Ian,
I installed the new boost elbow yesterday and moved my boost gauge connection from the wastegate hose to the 3/4" tap behind the fuel filter.
I got only about 24 lbs boost floored, but noticed no increase in acceleration times.
The 'EZ' dropped a whopping 3 seconds off my 0-60 time, however, that's only a decrease of 16' seconds to 13' seconds.
My 1996 1500 RAM 5. 2L 5 speed gasser was only 8 seconds 0-60. The new Toy Tundra is less than that!
What do I have to do to my 3500 RAM, for less than $2000, to best a Toyota Tundra?

I'll keep my Auto, it is not as bad as everyone thinks. Yes there are times I wish I had a stick ecspecially for slowing down, but mostly I am happy I have the Auto. Yes some of them are weak but thats the tradeoffs of mass production vs hand crafted. More often then not I think to myself man I am glad I have the auto, everytime I leave someone at a light, everytime I am eating on the way to work, everytime I am stuck in town traffic. And peoples heads turn when you can squel the tires from a standstill stop take off and then again when shifting to 2nd gear... ... . its hilarious.

 

[JR2]

Kat I am with you. I love my Auto.

I did the prudent thing and before I bombed the engine to much I upgraded with Bill K's TC/VB. Now I should not have to worry to much about what I do to it (with in reason of course)

I have to tell you folks. I just purchased a 2001. 5 2500 long bed 4x4 this month. Truck was built 10/00. 3:54 axle ratio. I got the Auto trans as I am tired of shifting. And of all things, a Diesel. I have been in the automotive service business for years and I swore I would never have a diesel. But, as my 97 Toyota T-100 would not pull a horse trailer, I now have a Dodge. All these posts on the Auto Trans worry me. So far, (1600 miles) this truck is a real jewel. The Cummins has really impressed me. The Trans shifts fine, although a bit jerky when the TC locks up. I hope when I hook up my two horse trailer I won't be sorry I got this truck. My T-100 was my fourth Toyota truck and I must say, Toyota builds one hell of a vehicle. If they ever build a heavy duty , full size 3/4 ton or one ton truck, watch out Ford, Chevy, Dodge, etc.

[Hot Shot]

Well folks I did'nt mean to stir the bucket, but oh well.

Talked to Pat at BD and gave him a good history on the transmission and it's activities over the last month or so.

For all of you who might think the Dodge transmission is junk-- I have put (as of today) 90,324 miles on my 2001 since March 1, 2000. I have towed numerous loads with combined gross weights of up to 34,000lbs. This is a good transmission.

The little resistor on port 31 was not installed by the dealer. I stopped at Radio Shack in Orange, TX and put one in. Slippppaaaagggeee is almost non existant and the accellarator does not pulsate anymore. It runs great, shift points are definite and firm, with no slippage without my trailer even when I punch it. #ad


As per Pat and Bills suggestion of Lube Gaurd, I will find some Monday and put it in.

BD and as well as a few others have been very helpfull with my problems. They have remained persistant in me keeping them up to date on what is going on. Kudo's to BD.

I will install a complete rebuild kit probobly by March. By then I should have around 110,000-120,000 miles. Just gettin her broken in. #ad

WOW, I'm really impressed. How did you put so many miles on the Ram since March 1, 2001? Here in Nevada, a different state of mind, we are still in 2000.
hehehe
Couldn't resist.

 

[SD-455]

Jeeeeeezzzzz,Walter,Did you have a bad day, along with the possibility of a bad transmission in your former truck??? I too am very happy with my modified auto. Turned the power up on your stick yet Walter? If so,hows that clutch holding up?Did you ever notice how many different combinations of trucks there are?Ever notice the different personalities of the owners of these trucks? Wonder what happens when the wrong two come together????

 

[Bill Kondolay]

Evan,

What part of what i said confuses or offends you?
To me telling the consumer or the TDR membership that a stock set of clutches can only handle 330'lbs of torque sounds like a scam to scare consumers into thinking they need to replace their clutches.

Please tell us who gave you this ridicilous information and who conducted the study.

I know John and Chuck from the POWERSHOP
and while i dont always agree with them, i have a great deal of respect for them and their opinions and that is why i refuse to believe they would condone this type of propaganda and scare tactics.
