CVT Transmission I had my ignition on ACC for a long period which drained my battery. After a jump my CVT transmission would not shift out of 2nd gear or in overdrive?

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

Replace the radiator as it is leaking internally. Remove and service the transmission as water in the transmission will destroy the bearings and clutches.
The best option if it has been leaking for a while is look for another vehicle ... possibly a cheaper option.

A problem a lot of drivers experience is their cars won't shift from first to second gear. That could lead to number of different problems, overheating being one of them. If you think there is a problem with your transmission then the first thing you should always do is check your transmission fluid levels.

This solves a lot of transmission problems but if you still can't shift then you may need to look at your throttle cables. A faulty throttle cable that has too much slack can prevent proper shifting, or shifting at all for that matter.

.

TPS SENSOR.
IT CONTROLS SHIFTING AT THE RIGHT TIME
AND COULD ALSO CAUSE ALL OF THE SYNMTHOMS
THAT YOU HAVE LISTED SOMETIMES WITH OUT GIVING YOU A CODE GOOD LUCK

need new transmition

I have a 2004 R2 - CVT fluid is to be changed every 40,000km. I've changed mine once already. Taking the drain plug out of the transmission pan drains 2-3L. New fluid is added to the CVT 'dipstick' tube, which is just behind the radiator with a black plastic head on the dipstick. A local CVT specialist sold me type NS-2 fluid, which has been working well for 12,000km. I also changed the filter on top of the transmission with a WIX 51365 which my autoparts shop found using the OEM filter part number. Hope this helps!

The transmission has gone into 'limp mode' by the sounds of it. When the transmission shifting control system stops working, it defaults to 2nd gear in order that you can still drive the vehicle, so that you can get it to a shop without a tow. The shifting of this transmission is controlled electronically.
Check the wiring and connectors for your transmission for any kind of damage, corrosion, etc. If you are blowing a turn signal fuse with Neutral, something for sure in there is short-circuited.

you are experiencing early to mid stage transmission failure.

The ford taurus is know for having a weak transmission, however if the transmission is serviced regularly you can avoid problems.
