The problem is the speedometer is not working and the computer cant tell ****** when to shift as it doesnt know the speed, have the speed sensor on the ****** checked. the speed sensor is the problem in most of these cases and is not hard to replace and i think that will solve your problem. also the check engine light should of come on also, if it did you can have the computer scanned to see if you have a speed sensor code, if you do then that will tell you its the speed sensor,this sensor is also called out shaft speed sensor. heres a picture to help you locate the speed sensor on the ******. good day hope this helps.What would cause transmisson only have 2  and 3rd - 2_14_2012_6_57_56_pm.gif

This may be an electronic control problem or a mechanical problem, what you must do to find the cause is to have the TCM 9transmission control module) tested for fault codes, this requires a special tool called a scanner to read the data stored in the TCM, based on that info you begin the diagnostics to repair the problem.

You will need to sort out the speedo so its works and then i think the gears will change as the computer senses the speed of the vehicle then process the information to tell teh gearbox to change gear .

Your transmission has gone in to a limp home mode or fail safe mode, trans computer has locked third gear to prevent any more damage. Needs a diagnostic scan to confirm fault code could disconnect battery for 10 mins and drive to see if problem reaccures. Trans computer common to fail.

I have a 1999 suzuki grand vitara 2.0 5 speed what speed sensor do I need and what colour


easter egg hunt 1million
Car speed?
or ABS speed sensors. we cant guess, whats wrong, can we.?
USA car,? we are USA, cars not here are vastly different.
so........????????
why ask not telling problem? scans told you sensor is bad
post the DTC error. speedo dead.Odom, dead? what?
J20 engine ,
5 speed stick shift box. manual trans,,m/t
4wd or 2wd?
toss coin NOT ABS sensors.
there are 2 speed sensors ill do all 3 permutations of car
4wd one or tail of transfer case
2wd one on tail of 5speed box.
any, the backup speed sensor in the speedometer cluster
89-98 years and was deleted 1999, usa.

why ask ,tell why. so we can be on the same page and
not have to document all the above.

color is of on concern, only correct part numbers matter !!!

colour (non usa spelling) is my only real useful HINT.
never said speedometer fails. or odometer fails
the trans is manual so no speed sensor needed ever there to shift automatially,its a stick

scan it yet.?
THAT BE FIRST.

i looked at our 1999 usa GV . serv. man
best i can tell speedo has new electronic head.
no speedo cable. first year, in fact. (i owned a 97 and 04)

so when VSS goes dead (say)
the speedo goes dead
odom goes dead
and ECU sets DTC errors for VSS dead.
3 clear symptoms.
some cars have different VSS1 to match, axle gears.
the vss gear on end .

on newer cars with stick shift
like mine now
the aBS sends speed to PCM
so there is no transmission speeds sensors at all , 6sp, m/t
so lacking symptoms, me bollixed.

What does the input sensor on your transmisson of a Pontiac G5 se 2007 do


The speedometer not working wouldn't be caused by an input sensor . The VSS - vehicle speed sensor is a direct input to the PCM , the PCM shares is info over the GMLAN data bus.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on GMLAN serial data message from the body control module (BCM). The BCM receives vehicle speed data from the powertrain control module (PCM)/engine control module (ECM) via the GMLAN serial data circuit. The speedometer will default to 0 km/h (0 mph) if:
?€¢
The PCM/ECM detects a malfunction in the vehicle speed sensor circuit.


?€¢
The BCM detects a loss of GMLAN communications with the PCM/ECM.


?€¢
The IPC detects a loss of GMLAN communications with the BCM.


The only way to diagnose these problems is with a factory scan tool , this will check inputs an outputs at the PCM an BCM to the instrument cluster . This avoids guessing an playing the parts game. Your best bet would be to take your vehicle to a qualified repair shop .
Same thing with trans not shifting out of first gear , could be a shift solenoid ! Does it shift manually , moving gear selector through the gears ?

The speedometer stop working


it could be a speed sensor problem causing this as the TCM doesn`t know what speed its at in order to shift gears.

Losing power going up hills


sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

My transmisson shifting from first to third gear and not goin to 2nd and fouth gear and I did a transmisson flush change the filter and it was working fine it jus develop tht problem can u tell me what...


The flush is something you never want to do,
as you found out

You may have sediment in the shift solenoids,
from however the flushing was done

Your only hope will be an honest trans shop,
