I sure appreciate the info ! I am guessing I do need that STAR tool to reprogram the plate ! Do you think perhaps Pep Boys or AAmco transmission may have the tools to finish the job?
The dealer did tell me i would have to reprogram the transmission.
However, when I disconnected the positive side of the battery to reset the check engine code... Now I am unable to connect with my OBD tool anymore to find out what engine codes are up. Check engine light is back on ! Could this be a fuse?

and for inquiring minds, Highland Automotive & Racing is in Clyde Texas. We build Japanese & European hotrods and drift machines.

CPS = crankshaft position sensor. I doubt that's the problem because if it fails the engine wouldn't start but 'input turbine sensor' is a new one on me and the CPS is one sensor that checks motor speed. Yes, fluid level can affect shifting....the slamming into gear is a low fluid symptom. You won't find many experts on the 5 speed because they are very reliable and rarely need repair. I doubt AAMCO or Pep Boys would have the STAR but you never know. I hate to beat a dead horse but I think you could be wasting your time if you can't measure the fluid level. Check the TCU like Glyn suggested as well. Under the front passenger side floorboard in a covered recess. You'll know if it's been affected if it's saturated with trans fluid.

highlandauto

ok, I feel like an idiot ! Could not see the dip tube with my own eyes ! Its only when I went to take a photo to post, showing it did not have a dip tube ! But boy was I wrong. Saw it after taking the photo but it is way down there! ok, checked the fluid level... it is ok ! Right where it is supposed to be at 80.
I guess I am stuck in Limp mode ! How do I get it out of that mode is the question!!!!!
I was told I had to program the transmission again after installing the Ectro_Conductor plate. is this true? if so... How do I go about resetting this to factory default?

Glyn M Ruck

Yes it is true - You now take this vehicle to someone with a STAR & capable of doing the software flash & have it set up to spec & cancel limp. - Choice = Dealer with STAR & latest software or Indy with STAR & latest software that knows what they are doing. I would be inclined to go to a dealer. At least you have saved all the labour cost on the repair & hopefully some spares mark up.

Good Luck You can't do this yourself & most shops can't do it either. After reprogramming I expect that the OBDII port will function normally.

highlandauto

ok, i figured it would need programming again ! anyone know what the cost is on having that done? why is it you have to program the elctro plate anyway?

Glyn M Ruck

To get the system to recognise it.

highlandauto

do you know what it would cost to get that flashed or programmed?
See, my problem is the closest dealer is 180 miles away.

Glyn M Ruck

You need local input on that - I lived in Dallas from 1994 to 1999 & in Marin County, Bay Area 2001/2002. I'm hopelessly out of date with US pricing

highlandauto

appreciated anyway Lol
Is that where you live? Cape Town? Its been a while since ive been in SA. last time I was in Pretoria while i was with 22nd regiment.

Glyn M Ruck

Yep! That's where I live. Had an international job with a multinational oil company & lived all over the world. Traveled globally > 200 days a year for many years. Now back home.

highlandauto

Nice !

Any outfit that builds hot rods is alright by me.
Didn’t intend to come across as an aloof and arrogant *** in my previous post. Kindly disregard.

Your initial "input turbine sensor fault" may have solely been as a result of a leaking or otherwise defective pilot bushing. When they fail, ATF often migrates up past the plug socket and into its harness to wreak havoc with the electronics. Trust you thoroughly cleaned the female end and its neighboring wires during replacement. The male junction is very fragile and easily damaged during reconnection. Don’t ask how I know. The pins must engage properly.

Because you’ve already replaced the electrohydraulic control unit (valve body), let’s assume it’s intact and ready to function correctly. Perhaps it’s the connection – or lack thereof – between the ETC/EGS (TCU) and the transmission that’s prompting limp mode. I’ve had my valve body out and its shift plate partially disassembled on the workbench chasing torque converter lockup gremlins. Although its adaptations may have been erased by doing so, it drove normally upon reassembly. I suspect programming parameters are stored in the ETC/EGS and can therefore enable regular function after an R&R. Don’t pull your hair out just yet.

As Glyn suggested, virtually all competent independent MB shops have STAR-DAS if, in fact, it’s required to activate your new electrohydraulic control unit. Around here, it’s typically ~$150 to hook it up; often much less to a tradesman on barter . Good luck.

i'm in california and was able to get my codes reset at a indy shop for $90 via star.

highlandauto

Hey I do appreciate the input ! Now its a question of finding someone competent with a Star-Das
Nice carputer system by the way !

TemjinX2

thanks...but yeah you dont really need to be that competent.

They only need to be competent enough to hook up a obdii port. they just reset the codes via laptop. its pretty straight forward. Its kinda a rip off they charged me $90 to do it when it only took like 5min, but i understand its a expensive system.

Glyn M Ruck

Mike - I know what you are saying - it's certainly not rocket science but it staggers me how many techs don't know their way around the STAR & you have to tell them what to do. It's really a matter of searching the menu, select & click. Reflashing the control software is equally easy.

John - regarding your excellent post. I've never personally had the valve body out for repair on a 722.6 so I bow to your superior knowledge. I've just been told by a usually trustworthy source that I gave a call on this one, that after a P0715 or similar induced limp & plate replacement that readaption is required with a STAR & software reflash is recommended.

I've only ever done a 1st to 2nd one way clutch replacement on a friend's car on the 722.6.

W203E35

It seems like you are moving closer and closer to the ocean. Dallas then to Marine County now to the most beautiful place I ever saw (clean and blue waters). Whats next an Island?

Here is my beach (Santa Monica)

Glyn M Ruck

Had an apartment overlooking the inner harbour in Sydney, Australia as well. In fact while living in Larkspur I also had a company paid for apartment in Sydney - they paid for both ends lucky me. I know Santa Monica & Venice Beach - Is it really that grubby now?

An Island would do - but inconvenient. I'm happy with my little piece of paradise

Sorry but i have to laugh. Many folks here on this board have successfully flushed the tranny fluid, and certainly are not ASE certified mechanics by following the instructions posted in various places on this site.
Which brings me to the reason I DIY.
You obviously didn't do your homework before starting, certified or otherwise and made a huge mess of things, ha just like when I take it to the dealer! he he

No one has up to this point managed to get their tranny locked into limp mode after a flush.
(Though one guy did put all the tranny fluid in the engine and blow the seals and the tranny.)

If you search you may find a thread started by me that pretty much covers everything you could ever want to know about the 722.6 tranny and how to flush it. Too bad you didn't read it.

As far as your EBD port not communicating, try checking the fuse..the port has it's own fuse,
I just had this happen recently. Fuse diagrams are on the site also.

Glyn M Ruck

In fairness, this was a little more than a transmission flush. While I've never understood the fear of auto boxes, many won't go as far as stripping the valve body.

C230 Sport Coup

The guy didn't have a dipstick, and EVEN IF HE HAD,
he didn't know where to put it, ie argued to the death that no
fill tube existed.

Thats pretty stupid. ESPECIALLY for a pro.
If there's something else wrong with the tranny it's also quite likely self induced
stupidity, from lack of research, or...I suppose over confidence that hey, a tranny is a tranny.
Well, perhaps except these cost 10 grand, and if you mess up you may have to replace it.
In many cases exceeding the value of the vehicle.

FYI to our machanic friend
MBUSA sells a services DVD ($60) for the W203 chassis that has lots of tranny info, and
also Haynes recently released a manual. ($25)
And of course if he had used the search button or google, he would've found all the info he needed
on tranny flushes, but the more complicated stuff might require a manual and a an SD.

Lastly as you've learned the hard way, dealer don't know crap.
You're 1st mistake was listening to them...I'm sure they really had no idea what was wrong,
just made up something that cost a lot...
You need to do your own diagnosis.

You're supposed to pump 3 quarts at a time...if you did all 9 at once you may have fried the
pump.
All necessary info IS posted on this site...

This thread perfectly illustrates why I do not trust mechanics.
Well, at this late stage of my life, I have ONE that I trust, who does
mercedes. He's not inexpensive, but he has a lot of overhead, and
and he knows it would be hard to pull the wool over my eyes.
He knows what he's doing, goes to MB classes, and
he doesn't sell you work you don't need and yeh, he's got SD.

highlandauto

THANKS EVERYONE FOR ALL YOUR INPUT ! wENT TO SEE A FRIEND WHO HAS A SNAPON SOLUS DIAGNOSTIC BOX... RESET ALL THE CODES AND TRANSMISSION CODES AND SHE RUNS LIKE A DREAM AGAIN !
I AM SO RELIEVED AND PLEASED WITH YOU GUYS SUPPORT AND HELP !
eSPECIALLY GLYN AND splinter & mleskovar ... YOU GUYS ROCK !

highlandauto

BY THE WAY, IM NOT STUPID ! tHE DIP TUBE WAS WAY DOWN THERE. COULD BARELY REACH IT ! and obviously I do know how to do this.... all i needed was to reset the computer for the transmission.. Apparently only a few of you knew this had to be done !
Besides... I saved $1200 doing it myself.

Glyn M Ruck

I'm delighted - This is good news & I've learned some more about these trannys by doing some research - That SnapOn Solus is a nice but expensive piece of kit. You obviously rebuilt the valve body properly. Out of interest - does the OBDII port now work after the adaption with the Solus? Nice saving!
