And what fault codes prompted you to replace these parts you listed? You never mention fuel pressure readings under a load, how about excessive exhaust system back pressure? Has the transmission been scanned for fault codes?
if you changed the driver side axle the problem is probaly not from what you did. but if you changed the pass side axle, which has a gear cut into it that the speed sensor gear mesh with, that you probaly damaged the speed sensor gear, pull the speed sensor out of the extention housing on the pass side of the transmission and inspect for damage.on the gear. if no damage and the wires are clean and tight ,replac speed sensor.
S is for low speeds with quick pickup. S is not economical. Thats why the
eco light is off.
Use B when you're climbing down steep hills and needs
to slow down without overheating the brakes.
The long answer:
Brake (B)A mode selectable on some Toyota models. In non-hybrid cars, this
mode lets the engine do compression braking, also known as engine braking,
typically when encountering a steep downhill. Instead of engaging the brakes,
the engine in a non-hybrid car switches to a lower gear and slows down the
spinning tires. The engine holds the car back, instead of the brakes slowing it
down. For hybrid cars, this mode converts the electric motor into a generator
for the battery. It is not the same as downshifting in a non-hybrid car, but it
has the same effect in slowing the car without using the brakes. GM called this
HR (hill retarder) and GR (grade retarder) in the 1950s.
Second (2 or S)This mode limits the transmission to the first two gear
ratios, or locks the transmission in second gear on Ford, Kia, and Honda models.
This can be used to drive in adverse conditions such as snow and ice, as well
as climbing or going down hills in the winter time. Some vehicles will
automatically shift up out of second gear in this mode if a certain RPM range is
reached in order to prevent engine damage. Although traditionally considered
second gear, there are other names used. Chrysler models
with a three-speed automatic since the late 1980s have called this gear 3
while using the traditional names for Drive and Low.
S or SportThis is commonly described as 'Sport mode'. It operates in an
identical manner as 'D' mode, except that the upshifts change much higher up the
engine's rev range. This has the effect on maximising all the available engine
output, and therefore enhances the performance of the vehicle, particularly
during acceleration. This mode will also downchange much higher up the rev range
compared to 'D' mode, maximising the effects of engine
braking. This mode will have a detrimental effect on fuel economy. Hyundai
has a Norm/Power switch next to the gearshift for this purpose on the Tiburon.
GM also used S to indicate a "super" mode, being the same as the 2 position on a
Chrysler, shifting between only first and second gears.
use B or S for general driving as both are very low on fuel efficiency.
if its stay in second speed the computer put the tramission in limp mode because there a problem in the trasmission you need to get your van pass on a scanner to see the code it could simply be the input or output sensor there sensor on the transmission and to reset that simply disconnect the battery for 2 minute after you see your trams will change all speed let me no and thanks for using fixya
Check the connection to the vehicle speed sensor. You can check the vehicle speed sensor by using a voltmeter set at millivolt. Then pass a metallic object close to it. The sensor should induce voltage as you pass the metallic object close to it. If not replace the vehicle speed sensor.
hi passing gear is actually your transmision drpping down to second gear.if you hit the gas hard.if you hit the gas lightly it will only drop out of overdrive and go into third and not go into passing gear.
is it when the car is in 3rd gear automatique trasmission and change to lock up mode if its what you call that its lock up selenoid its on the driver side of trasmission on the side cover its call lock up switch too please dont forget to rate this if its a fixya its better for me thank you advance
If the actual gear stick is hard to move you will find the linkages are stuck on something, if it moves freely and still doesnt change theres two things it could be, first is motor was incorrectly installed or second is the gearbox has gone into limp mode, limp mode is a factory set mode that keeps the car in 3rd gear for a 3 speed or 4th in a 4 speed, in the ba's i had this problem with my car, limp mode is only a safety measure to get you home and should be looked at immediatley.
