EZ box is great, trans seems to have a problem, HELP!

[kcnizdodge]

I installed the Edge EZ box on my truck last Friday and took it for a 330 mile trip over the weekend. I love the power, got better fuel economy, but I had to jump on the throttle once and geeze it took off like a rocket, but at about 3000 rpm, the dang thang just fell on its face, like the trans had gone into neutral, or worse, puked all over the street. The tach jumped up to 3500 before I got off the throttle, and then back around 2900 rpm, the trans shifted to second gear and we kept on going. This is NOT COOL!!



Is there a problem with the trans? Does the EZ give more power on setting 2 than the trans can handle? Scared the crap outta me, and there is still a pucker mark on my wife's side of the seat!!



Has anyone else run into this problem? Do I need to take a trip to the dealer to have this checked out? No engine light, all seems to be fine, just happens when I land on the throttle and go WOT!



Any thoughts or ideas will be welcome.

NEVER had this probelm... bump to help him out

 

[kcnizdodge]

Come on guys! I can't believe 140+ people have looked at this and nobody has any ideas!! Please, help me out here, I am stumped!!

 

[dieselpilot1969]

Uh what kind of transmission do you have in your truck?

 

[MMeier]

A trip to the dealer probably is not in your best interest, a trip to a aftermarket outfit is probably your best bet!!

 

[kcnizdodge]

The truck hast the 47RE automatic trans. I like the trans, shifts kinda funny, but seems to work except under WOT.



A trip to the aftermarket dudes is out of the question right now. Besides, I paid a bundle for the extended warranty and I am gonna use it to death.



I have driven chevys with TH350s and TH400s and MOPARs with the A727 and NEVER run into a problem like this before. I have had the engine fall on its face, but never the trans like this one does.

You take that thing to the dealer theyll see your boost numbers are higher than what they should be and vboid every warranty you have ... . Id recomend unhooking your batteries for 25 minutes completely... hooking them back up. . and try it. . Just an idea. .



ALSO. .



Do a dash test see if you have any codes... (hit odometer button and tiurn on key at the same time... )

 

[kcnizdodge]

If I disconnect the batteries for 25 minutes, does that erase the memory of what happened with the system or is that to allow the system to sort of "reboot" and come back to a known state?



I will also do the check for codes. I haven't had the check engine light come on since I put the EZ in though.



Thanks for the suggestions, I appreciate all the help!!

 

[yycguy]

For what it's worth another member told me this way to check codes;



"To get the engine codes, cycle the key from off to on 3 times without starting the truck. The odometer will read out the codes, one at a time. When it's finished, it will say "done". "



And as for taking it to the Dealer? good luck, I am just in the midst of a battle with those _____ ( can't us the name I'd like to)

 

[rogerblind]

Bringing this back to the top. I too, like AGrady, would like to know if disconnecting the batteries for 25 minutes, erases the memory of what happened with the system or does it just allow the system to sort of "reboot" and come back to a known state? Does anyone know the answer? Thanks!!

 

[slavallee]

Unhooking the batteries will NOT erase any previously set codes or bost/ timing/ fuel delivery values. The dealer will be able to spot it if he cares to.



You wanna play, be prepared to pay$$.

From the "03" maintenance manual Caution: Erasing the DTCs, either with the DRB III or by disconnecting the battery also clears all freeze frame data" sounds to me like all memory is erased?? Oo.



If someone else can check "Emmissions Control Chapter" pg 25-7

Let me know if I'm interperting this correctly.

My truck sits in storage 11 months a year (unfortunately!) with the batteries disconnected. It doesn't seem to erase anything of any importance, but maybe codes I want erased anyway. That would be nice!

Bill,



I looked at the service manual as you suggested and that is what it looks like to me. If you disconnect the battery cables the Freeze Frame data will be erased.



I guess this can be a good or bad thing depending on if the Freeze Frame data can assist them in resolving the customer's problem.



However, if it saves information stored from the EZ box (as an example) we may want to clear it before taking a trip to the dealer for warranty work.



I may give this a try before going to the dealer to see if this is a trans problem or not.



Thanks for the info!!



I just bought the 2003 Service Manual on CD just to look this up. It was well worth the 7 bucks plus shipping I paid!

WTF. .

 

[rogerblind]

Regarding "WTF. " Retirement home/vehicle all in place when unexpected events delayed retirement. Sure enjoy that truck for one month a year though! Hopefully 12 months in the near future!!



PS: Have another (2nd gen) for daily driver, so don't feel too deprived.

Did you install a new little brass elbow in the turbo or block the wastegate? If you didnt I wouldnt think you set any codes. Your transmission should hold with the EZ. Take it by a Autozone and they can read any codes. If no codes go ahead and smoke the transmission IF!!! it is covered by warranty.

Nope, didn't install the boost elbow. I thought I would try the EZ without it to start with. I know the trans is covered on the warranty because we made sure that was part of the coverage. I am just gonna go ahead and drive it and if it pukes the trans, then DC can put in a new one!



Sometimes I wish it had been a 6 speed. That is what I would buy if I were ordering one today?



One thought, would putting a shift kit in the auto make any difference? I know due to the warranty thing, I can't, I was just thinking out loud (gets me in trouble every time!!

I replied to you the other night when they were doing maintenance on the TDR site. Seems like my reply must have gotten zapped into cyberspace when they shut down the forums. I figured I'd try again since "better late than never".



The problem I experienced when I plugged in my Edge EZ is so similar to yours, I wanted to let you know what I've found out. When I plugged in the EZ and did a test drive the truck started to "buck and hesitate" at higher RPM range. I didn't get as high as you did though. Mine would go from 2800 - 3100 RPMs. I thought it was a fuel or air problem. I was surprised by the whole thing so I really didn't drive much except to get back home and immediately unplugged the EZ.



I installed a cold air kit a couple of days later and on the way home I wanted to try it out. I still had the EZ unplugged. The truck would hesitate and buck between each shift point. I also immediately threw an overboost code and check engine light came on. I HAD installed the boost elbow and with the EZ unplugged the ECM knew it.



I called the tech support guy at Edge and he basically said the truck needs to re-learn or re-program for the new power and driver input (as in I was mashing the go pedal). He said all would be well after putting some miles on the truck. I figured this was hog wash! He did tell me they would replace the unit if my problems persisted and I could eliminate the box as a possible cause of the problem.



After I talked to Edge, I realized I had probably never floored the go pedal at all before. I called a buddy of mine who is a die hard gear head and also a computer guru. He loves to play with ECM programs so things go really fast. He confirmed what Edge told me about the ECM "learning" to recognize a "typical" driving pattern for a vehicle. I'm not explaining as well as he can but the short version is it wasn't hog wash.



I plugged the EZ back in and went out and did a bunch of 0-70 MPH runs and could tell the hesitation and bucking seemed to be the transmission "hunting" for lockup at shift points. transmission just seemed to slip. My transmission has always shifted a litttle quirky since I put the 315s on. I haven't had the speedo calibrated for the change. I'm not very knowledgeable about trannys but I think this is all happening through the electronic controller on the transmission.



After a week of driving, seems like truck has "learned" very well!This electronic stuff amazes me!! The truck is running great and the transmission seems to be shifting like the transmission I knew pre EZ. I still think I want to get the recalibration done because I think it will help the shift points some. A transmission controller might be the ticket. I want to keep things stock there as long as I can also.



I did try to clear my over-boost code. I disconnected batteries completely, turned ignition to on and let set for about an hour. When I reconnected the batteries, the code and Check Engine Light were still there. There seems to be some uninterruptable power supply battery somewhere to maintain ECM memory! I had local parts store hook up a scanner to clear the code. Their scanner failed also but I'm hoping it is just a problem with that scanner. I'll try another one I know of.



Hopefully by now, your truck has reprogrammed also and you are a happy camper.

There are a couple of things that could be going wrong with your transmission. A governer circut could be bad. Too much power and internal leaks could effect shifting. You need to call Bill K at DTT. He will tell you what is wrong with your transmission. www.dieseltrans.com

He is the master guru of the 47re.



As for you guys that are bombing your trucks and want to take them to the dealer.

You cannot clear the codes without an OBDII scanner. You will get caught and VOID your warranty. Some mechanics are cool about this but watch the service writers. I know for a fact the major kudos when the void a warranty for adding a fueling box of any type.

Repeat after me:

" I am my own warranty station. "



Get your money back for the extended warranty, have them put it too the pricipal on your loan. DC warranty sux anyway. MOst of the mechanics are didlos and don't have a clue. If you want to use your warranty, do not add a box. You will get caught.
