ST202 Auto Transmission fault

I have a 94 Import ST202 with 4 speed auto transmission with a faulty speedometer. On the occasions that it works there is no issue with the transmission but then it usually either works for a few minutes then fails, or doesn't work at all.

When it isn't working the transmission starts in 1st and then struggles to change into second. Also, upon stopping it doesn't always change back into 1st. When it behaves like this even with my foot down on the accelerator it only changes at 4000rpm as opposed to around 6800rpm like it used to.

Please can anybody suggest a solution that isn't going to break the bank?

SOURCE: how to use the overdrive on the auto.transmission.

the overdrive button on your automatic transmission is for cruising on the highway basically like having another gear for better economy careful not to use it when your not on the highway because lugging the car in overdrive when its not needed will cause higher fuel consumption other than that you should have no problems just get out on the highway and push and away you go

Could be a solenoid in the tranny, or the throttle position sensor need calibrating.

SOURCE: Sluggish transmission engagement. Traveling at

changing your VSS is easy , the hardest part is finding it...look around the housing near your CV axles..the differential in there near there is a 8 or 10mm bolt holding it in witha wire connector on the end...if you pull it out you will see a plastic gear on the end of the sensor.... YOU CAN DO IT!!!!

Transmission Fault code 17

a real DTC code.
17 , 94 Accord
the means VSS is dead, vehical speed sensor (miles per hour)
so , that begs the question is the speedometer dead or odometer
dead or acting funny IN ANY WAY?
is this an A/T Car or M/T car, both have VSS, so... cant answer.
Auto or stick, ill pretend, AUTO.
VSS moves all over the place, in all cars. all models and all years.
on this car, its odd.
quote FSM:
Accords and Preludes use an external sensor mounted on top of the power steering speed sensor in the engine compartment. The power steering speed sensor is gear-driven and controls the steering boost in relation to the speed of the vehicle. An electric pulser unit is mounted on top of this unit and is coupled to it by a small shaft. The motion from the lower unit is transferred to the upper unit; the resultant electrical signal is sent to the appropriate control units.

most cars old use the speedometer VSS sensor inside
on newer cars 1996 (on avg) the sensor is on the tail shaft. and in speedo.
on very new cars there are 3 VSS.... (dont ask)

on my 96 car, the tranny VSS can fail and then FALL back to the
SPEEDO head. and tranny still shifts but is funky,
the FSM covers all this, i recommend getting one, to understand
how it all works.

your car has and electronic speedometer
the VSS orange wire , sends speed data to the PCM, TCM, cruise.
the PCM then sets the speedo dial, and uses this info to run TCM
controls to the transmission.
your orange wire signal is dead or flaky.

it indicates that the VSS or TCM is faulty
one reports the vehicle speed to the TCM to organize when to change ratios and to the speedometer as to vehicle speed
the other tells what servo/ solenoids to change to select the right ratios for the road speed/ engine rpms
try having the fault codes read by an accredited transmission shop or have the problem diagnosed by the shop and a quote

I have reverse and first gear

I'm guessing you don't have any other gears? If your speedometer doesn't work, then you need to replace the vehicle speed sensor (VSS), if the speedometer does work, then you probably need to replace the turbine speed sensor (TSS). The transmission can't shift if it doesn't know how fast the vehicle or transmission is moving. Since you didn't way what model and engine you have I can't tell you where the VSS or TSS is located. You can buy these sensors at a local auto part store, such as Auto Zone, and they can give you the specific location of the sensors on the transmission.

My truck speedometer stays at 0 until about 20 mph. also it stays in low gear too long. 4x4 auto 318.

The two problems may or may not be related. First go to the vehicle speed sensor on the rear axle to see that the wiring and connection is clean and tight to the sensor. If it is all good there then change the vehicle speed sensor, this should fix the speedometer. The Dodge transmission has it's own speed sensor and if it is affecting the shift, it should be storing a transmission code. Also the wiring harness inside the transmission may be faulty.
