I have an Audi A6 3.0 o1j cvt 2003. I recently had a problem with the transmission it has less power on it's reverse and on 1st gear it tends to buckle to a stop. I ran a computer and it read P0706 transmission range sensor. I don't know what part I need. The dealer said I need a TCM but I dont believe that

2 TRANSMISSION REPLACED, GEE 1: USED,2: NEW3;REBUILT.
MOST USED BOXES ARE NO GOOD , SORRY BUT NOT GOOD.

NO CAR TOLD AND NONE ARE SOLD USA. HERE.
THIS IS WHAT I SEE. (JUST NO CAR TOLD)
SO SCANNING THE PCM(TCM) IS TO HARD? SCAN IT.!!!!!!
THE SHIFTER IS PRNDL,
SOME Y12 DID HAVE CVT BOX
YOU POSTED NO MODEL CAR AND THEN POSTED Y12
AND Y12 SERIES HAD 2 BOXES YOU FAILED TO TELL.
NO TOLD WHAT ENGINE YOU HAVE, OR YEAR???????????
4-speed E-ATx automatic (1.2/1.6 L)
JATCO XTRONIC CVT-M6 (1.5/1.8 L)

GENERIC NORMAL NOT CVT HORROR BOX ANSWER.

SO THERE ARE 3 SELECTIONS (ALL 3 FAIL) NOT TOLD THIS.
LOW,
REVERSE
AND DRIVE
SO ALL THOSE ARE STUCK ON FORWARD 1ST GEAR????
NOT TOLD THAT,
BUT IF IS TRUE THEN THE SHIFT LINKAGE ON THIS CAR IS BAD
BECAUSE REVERSE MUST WORK.AND REV MUST NOT MOVE CAR FORWARD , IF DOES SAY SO.

A/T BOXES ARE COMPLEX. AND SO 'ARE ALL TESTS DONE CORRECTLY.
THE SERVICE MANUAL IF YOU READ IT HAS ALL THE ON CAR CHECKS TO DO MY GUESS 2005 YEAR CAR.
Y12 BOX.
FLUID LEVELS GOOD, NOT LOOK LIKE TAR OR STINKS BURNT.
and dip stick ATF fluid to white paper not full of metal shinny dust? for sure seen on CVT box bad.

ENGINE IS NOT WEAK. (50 WAYS FOR ENGINES TOP FAIL AND BE WEAK OR DEAD) THE PCM (TCM) ONLY UPSHIFT IF ENGINE LOAD AND RPM AND ROAD SPEED ALLOW IT TO DO THAT)
IT IS PURELY ELECTRONICALLY SHIFTED, 1,2,3,4 UP
THE STALL TEST.
IN DRIVE OR IN LOW.
DO THE STALL TESTS, PER THE MANUAL
MY GUESS IS DOING THIS TEST ON CVT IS (NOT WISE)
CLASSIC SIMPLE TEST . A 3 TO 5 SECOND TEST MAX.
HAND BRAKE SET, HARD,
CAR POINTED IN A SAFE DIRECTION, NO KIDS THERE ?
NO CLIFFS (GRIN)
FOOT ON FLOOR BRAKE HARD.PRESSED AND HELD.

ENGINE RUNNING STOMP ON THE THROTTLE PEDAL
IN DRIVE.
HARD SEE RPM RISE, CAR WANTS TO MOVE, AND MAY HIT 3000 TO 3500 RPM THIS THE TC CLUTCH SLIPPING NOW.
AND IS PASSING THIS NOW.
END CLASSIC A/T TEST.

AND THE TC WILL GET HOT SO END THE TEST AT 3 SECONDS
THIS PROVES (MOSTLy ) ENGINE IS NOT WEAK.
IT DOES NO PROVE ROAD SPEED SENSORS WORK,
SCANNING THE PCM LEARNS THAT BUT FAILED TO DO SO)


AND PROVES CLUTCHES TC MAIN AND INSIDE FIRST GEAR CLUTCHES NOT BAD OR HUGE SLIPPING AND RPM GOES WILD TO 5000 RPM AND IF DOES ABORT THE TEST.

THIS IS ALL STANDARD TEST. ON ALL CARS A/T, NO NOT SURE ME ANY CVT BOX. (ID NEVER BUY ONE)

FUSES GOOD CABLES AND CONNECTORS GOOD
REVERSE WORKS AND

END WILD GUESS WHAT TRANSMISSION IS THERE
NO MODEL CAR, ir is a VAN
NO ENGINE TOLD
NO COUNTRY TOLD
NO TRANSMISSION MODEL TOld
not old is 2nd or3rd used, new or rebuilt wow not one clue.
NO Year car told 2005 to present sure. and a useless fact.
just vague y12,

all we know is this. and is no answer. a VAN.

the tcm shifts the transmission but CVT does not shift,. it just changes ratios on the 2 pulleys inside.(not via gears at all)


only planetary gear set a/t boxes shift! using clutch packs(modern)
yes CVT will have special gear set just for reverse.
that is it for no car and no transmission told
and is 100% all about all about

I went google and came up with the following recommended oil
castrol transmax A cvt
the reading is --full synthetic continuous variable transmission fluid developed for Audi. It is the only CVTF approved for use in the vl 300 and vl 3800 multitronic (CVT chain) transmission applications in the Audi A4 ( up to 2007 models ). Audi A6 and Audi A8
features &benefits
exceptional steel on steel friction durability maintains transmission performance
good gear wear protection prolongs the performance and life of transmission
high shear stability and enhanced anti-foaming and air release characteristics maintain effective lubrication
Specifications and technical data
VW TL 52180
only approved product for Audi cars with multitronic transmissions
corresponds to part no G 052 180
this is an extract from the www.castrol.com web page
go google and type in--- type of transmission oil used in audi cvt transmissions---
there is a penrite site that has a special oil for Audi CVT transmissions and no doubt there will be other sites for Mobil , shell and others
hope this helps

Have the oil changed and the filter checked . I have a Mitsubishi lancer and it is in good nick but If I apply power before the shift happens it chirps the tyres . have the bands and clutch pack adjusted Run fault codes to check for faulty solenoids and servos.

Sounds like one of the levers inside the transmission is either broken or otherwise disengaged. Remove the shifter to see if you can see any obvious reason.

no gears indicates that the torque converter clutch servo/solenoid s faulty
probably a disconnected wire from your working with the others

Im having the exact same problem, word for word, with my 1995 3000gt! Anyone have any ideas on how to fix it please???

\'93 Hyundai Lantra, automatic transmission has trouble changing up from 1st to 2nd, it tends to rev on a bit, clunks once or twice before changing to 2nd, other gears seem to be ok. Oil levels are ok and have recently replaced the transmission oil (yes the correct oil was used)

sound like 1st gear might be slipping or stripped

Sounds like the shift lever is not coming completely out of 2nd gear. So, by shifting into 1st gear, you recenter the shift lever. You can confirm this by going under the truck and moving the 1st - 2nd lever on the side of the transmission with your hand. If the shifter goes into reverse after you manually recenter the 1-2 lever, then you need to correct the problem that prevents the "normal" recentering of the 1-2 shift lever.

Possibilities are: Bent shift rod; worn shifter; worn shift rod at connection to shift lever on transmission.

check and replace filter and fluids just like oil it tends to burn up and blacking and needs to be changed and flushed checking your tranny fluid it should be a red color not a dark red or with a black tint
