I have a 1999 c280 with 722.6 trans. scan code said otput turbine speed sensor bad,i changed the conductor plate no change, i found fluid in tcm, cleaned module and harness, still wont shift out of first, replaced tcm with used tcm now the car wont even start,do i need to program tcu wit car vin to make it run and shift?

no year car, no engine size, no transmission name , nor country
my guess this tranny A/t , fails 3 >4 shift/ that it?
fails to shift or shifts up and FLARE (aka false neutrals)
not told the problem at all just parts changed wrong
there are 50 causes (seals old and bad and leak vast)
and 20 or more bad symptoms on a failing tranny

SCAN THE PCM YET/? p07XX ERRORS
I try to buy it on world market and see this.
TRANS UA-NCP25, (car code name)
TRANSVERSE BOX FWD.
BASE TRANS, AISIN, U340F-04A

THERE ARE MANY TEST. FOR ANY A/T
1: AFT not burnt, not overfilled or under
2: scans show what is wrong/ not scanned is no good.
3: line pressure port tested for a PSI in all shifted gears PRNDL.
4: if EBOX. , 3>4 solenoid bad, (not shifting to 4th)
5: PCVS some have pressure control valve, Ebox, to set or trim main line pressure. (as in modulated)
5a and newer have gear pressure detector switches.that can all fail if above fails.
6: all speed sensord good but the scans told you that if you looked.
7: endless leaks causes #3 to fail sure. its 20 years old why not?
maker AISIN , bet 1.
and some version of A340 but not told. ending in E,F,H,S
8:heat sensor in box (Ebox) that cause limphome mode to cool it down.does box work COLD"?

not guess, learn that, or even read its side plate tag
huge evolution 2000 to now, for sure new pressure control
modulated solenoids and 2 or 3 speed sensors.
Any car made,if has EBOx, (means TCM brain shifted )
must be scanned first after levels ATF correct hot.

there are turbine speed sensors that are located in the area you mentioned
if they are faulty ,the TCM has difficulty in correctly changing gears

still won't shift The word button , tips hand that it is a automatic trans,
but not which one. they had 2 that year, 42/44re and
the AW4 box, has a TCM (tranny brain.)
and all tranny brains go to limphome mode, (skipping or freezing 2nd) if inputs are WRONG.
the TCM can be scanned, to see why, skipping this step misses the boat,

I have the 1995 FSM book. chapter 21.
42 or 44RE trans? is that yours. the tag on side tells you what it is. look for the tag, and learn what car run for a drive-line.

see" trans... opt" here. ZJ
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

page 21-45 is diagnosis page, in the FSM book.
ON car service, and step 2 is scan it. (step one is fuses. levels)
ever consider read this book on this car and this trans?

here is the non tool way,
https://www.youtube.com/watch?v=TWXaoC3Qi7g

i use a Innova 3140 , tool that does jeep 1993-95, OBD1
i have not tried, to see if it will log a trans DTC;s
using a real scan tool , helps greatly to see all TCM codes.
most TCM can do 10 error code, all very revealing.

make sure the transmission is grounded, with a good ground strap
seen people replace trans 3 times, then do strap last. sad.

Trans issues are many
(ill skip bad trans)

1. wiring bad, from TCM to trans, or from TCM to all sensors. to it.
2. bad TCM
3. lost power 12vdc to TCM for any reasons.
4. lost ground to trans or TCM.

a scan tool that can scan this back in 1995 was the DRB-ii
DOES THAT HELP?

no what matters is if the pulses are good.
and the transmission not slipping.
the TCM is not genious level yet.

are you asking what P0500 means.
or want us to tell you all things stated in fSM for this code.
what? guessing you can do .
ever heard of alldata.com (DIY)
ever read that page on 500s?
i guess not.
3.3L v6 ?
quote:
Trouble Code Conditions: P0500
VEHICLE SPEED SENSOR "A"
The ECM detects following conditions simultaneously for 2 secnonds (1 trip detection logic):
No SPD (speed sensor) signal while ECM detects NC (trans­mission counter gear) signal is more than 300 RPM Park/Neutral position switch is OFF (When shift lever is in other than P and N positions) Possible Causes:

• Open or short in speed sensor circuit
• Speed sensor
• Combination meter
• ECM
• Skid control ECU

im trying to decode that too, the sensors
are called, C3 counter gear sensor, and Turbin T3 sensor
but the book keeps changing names in the book.

i think it means, counter gear shows correct RPM
but the turbine gear sensor T3 is dead.
while in gear. is too hard for them to say. so i said it.
and my guess, moving,
after all transmission slip moving
in fact i can scan your car and prove that
i scan it in park, then indrive, no moving
got 500s, or are 500 happening flogging engine.

but the ECU signal is either dead for turbine sensor or is way too slow. see incongruity from 300+ rpm on counter gear.

500 means dead, not intermittant.
i looked at all codes for turbine.

so my best guess (no real fsm only alldata)
is Turbine is the clutch sensor. (input rpm to trans-clutch)
and counter gear is tail shaft sensor.? (output speed)
so the front clutch sensor is dead
or being grounded out, or is not connected, (rusty conns?)

Most FSM made do a poor job, at showing possible bad parts.

here is better

1. the sensor is weak or dead
2. the sensor connections are bad.
3. the sensor, signals do not arrive at the PCM /TCM, due to bad wires, or anything on that line shorting that line out.
4. better (yes?, this is electronics) no a parts swap game.

if the car drives ok then the trans does not slip.
the TCM sees both ends and can detect, bad sensors or gross slip.
i think it means bad sensor. in this case only.

what does this mean?

1. having difficulty locating it

can buy one, find one, can't insert it, or?

I do not believe so . Code p0715 if that relates to your question refers to the turbine shaft speed(TSS) sensor-circuit malfunction===causes wiring--TSS sensor--ECM/TCM
The drive speed sensor is the sensor that works the speedo and sends impulses to the transmission control module to change gears in relation to the turbine speed sensor
This is how the TCM knows when to change ratios in the transmission because of the differences in recorded speeds of the engine torque convertor and the drive shaft

No --- it just needs the TCM checked out as that is indicated by the series of faults.

Everything I have read says... it must be PRE-PROGRAMMED
TO WORK correctly... (not-plug & play).

You need to post your original part number
Your TCM or TCU or whatever it is called
is definitely shared with OTHER Mercedes models

I have found them on AUDI...

Merc forums might be the place...

Most the meaningful dialog came from a single FORUM
"1994c220" (Go Hawkeyes...

Trans Control Module TCM

Car FORUMS & clubs get a lot off the point...
But this guy stays on course... but it is time for
heading into the wine country...

Later for whines
(I'm intellectually challenged on MERCs...
but I love the research (ROCKAUTO was no help on this one)...

Sorry about the SPAM answer f/Todd: that's all he does...!!

You will need your transmission tested or checked out

The Turbine Sensor may be the one closest to the engine
and is any indication of input speed from the converter,
vs: the other trans sensors that are farther back on the case.

Now the issue is, can you get your hand between the floor pan
to change it,if it is bad.

First of all, these codes are what are called "Powertrain Trouble Codes' (that's what the "P" means P=Powertrain). TCM Request (Transmission Control Module = TCM). The request was to turn on the 'Check Engine" light.
P0720 - output speed sensor circuit malfunction
P0715 - Input speed sensor (turbin speed) circuit malfunction
P0442 - Evaporative Emission System Leak (Small Leak)
P0455 - Evaporative Emission System Leak (Large Leak)
Check fuel filler cap problems - for Evap Emiss leaks
Replace the pulse generators & have the trans fluid replaced/flushed.
The Main Catalyst System Efficiency Bank 1 Is P0420, not P0442
If you had P0420 code, the catalytic converter is shot... and that's an expensive component.

Hello jjames696...The gearbox fault light has come on because the transmission control module (TCM) has received a fault signal from one or both of the two trans. sensors....The Output Shaft Speed (OSS) Sensor and/or Turbine Shaft Speed (TSS) Sensor.The TCM has now defaulted to limp mode...A diagnostic scan needs to be run...An OBD II scanner will retrive a P1722 fault code, the only code in it's library for the ZF5HP24 transmission. The WDS / IDS will pull other codes not found in the standard OBDII library (dealer or good transmission shop)
When was the last time the transmission was serviced? Manual shifting will take it's toll on the fluid quickly.
The transmission is sealed, no dipstick (which i think is a bad idea) You can check the fluid level by removing a plug on the passenger side of the case, you should be able to touch the fluid with your finger. Jaguar fluid is VERY expensive, Mobil 1 synthetic will work and meets ESSO specs.
Personally...i would change fluid every 25-30k.
Hopefully all you have is a bad sensor or a stuck solenoid and no internal componet damage.
Good luck, hope this answers your question...please take time to rate my fixya reply.
