1992 Subaru legacy wagon will not shift up from first gear. it is an AT.


run the fault but all you describe is operated from the VSS sensor ( vehicle speed sensor)
it tells the cruise control the vehicle speed , tells the TCM the vehicle speed so that ratios can be changed, activates the speedo,and will report with a check engine light to report a transmission problem
run the fault codes first

Landcruiser amazon 2000 diesel 4.2 was driving today and all of a sudden the vehicle was in D for drive and was showing first gear on the dash, and wouldnt drive over 20mph and wouldn't change


the tcm. (trans control module) has detected a fault in the transmission. it won't change because its in limp home mode.
the vss sensor may have failed. let the dealer or transmission shop run a scan tool on it.

Check engine light came on vehicle shut down,Nissan Wingroad Y11,on checking with tech it showed Air flow censer, changed it drove about 50metres light came back on car stutter shut down. help


First inspect the boot from sensor to the intake manifold for cracks,inspect all the vacuum hoses to the intake.
second unplug the connector and inspect the terminal.Sometimes the plastic is burn and the wire pusht out of terminal. insert the wire all the way in or replace the pigtail.
plug scanner and monitor the air flow and air temperature on live data.
inspect the wire harness for damage to engine ground.
good luck

I Have A 2000 Hyundai Accent And The Codes P1529 and P0722 Came Up. What Does This Mean. Please Help Me Out.


P1529 - MIL light request

P0722 - Transmission Pulse Generator B. The Pulse Generator detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal. The pulse signal is sent to the Transmission Control Module (TCM) which converts it into vehicle speed. The code is detected when the Pulse Generator B failed to provide a signal to the TCM upon initial movement of vehicle.

Symptoms:
- Engine Light On (or Service Engine Soon Warning Light)
- Speedometer improper reading
- Possible shifting problems

Possible Causes:
- Pulse Generator B harness or connectors
- Pulse Generator B circuit is open or shorted
- Pulse Generator B

I have a 42re trans (4x2). My previous trans would always pull out in 2nd gear shifting regular thru the rest. Rarely did it pull out in 1st gear. Eventually the trans went while on the highway. Vehicle...


2001 grand cherokee?
nor years of all parts swapped.
swaps are super complex topics, endless possibles.

dont expect magic from any TCM.
they cant tell you ever possible way things can be wrong
it will fail to shift right if things are wrong,
the trans TCM can go to limphome mode, read the service manual chapter 21 yet its free, posted here 300 times.
forget the silly engine , light (CEL) use only a scan tool one that can read all factory codes not some $20 tool.
CEL lamp is for failing smog. only. never trust it, if out.

i say bad shift solinoids.
the TCM can see late shift error.s but maybe not all.
stick in 1st is a hard failure.
all inputs to the TCM must be correct for the shift to 2nd happens.
check all inputs.
if those are then see if the TCM did shift to 2nd, but the solenoids ignored the logic inputs to the solenoids.
solenoids have many failure mods
dead. (stuck closed)
stuck open, valve open.
or leaking. (leaking can cause stuck in 1st and confuse any TCM)

leaking means breached, valve leaks where it must not. ever.

My speedometer will not work check engine light goes on and off and the overdrive indicator light flashes. All this happens intermittently with hotter weather it seemingly happens more frequently. Scanned...


code p 0500 is for the vehicle speed sensor (VSS) which works the speedo as well as the ratio changes
code p0720 refers to the output shaft sensor --ECM or transmission control module (TCM)
the vss reports to the tcm which reads the road speed and gear ratio and shifts the appropriate solenoid

There are two different problems first off the speed indicator dial will go haywire it flickers and changes by itself as you drive or while its idling.When you turn the heater blower on the car acts up...


Wow a lot going on there it seems. Well for starters 96 was the year all vehicles made in and after that year had to be obdII (onboard diagnostic 2) compliant, which means a common scanner communication point, location (within reason) and a set of global obd2 codes for all makes and models to help with emission standards and diagnostics of such systems. A late 95 may have called a 96 and be only obd1 and another 96 be obdII possibly causing discrepancies in the wiring, or even simpler a different transmission option, etc. Secondly vehicle speed sensors are normally magnetic induction sensors on late model vehicles, but can be hall effect or mechanical. Each one produces a different signal, for example a magnetic induction sensor will produce an analog signal to the pcm or tcm converted inside to digital signal so the computer understands and can intepret the information. A hall effect will produce a digital signal and send it to the pcm or tcm for direct interpretation. Normally input and output shaft speed sensors are used to tell the tcm what gear the transmission is in when compared to one another against a chart in its memory. On some models they will have vehicle speed sensors as well that will tell the pcm the vehicle speed which will relay that information to the instrument cluster to operate the speedo head. If you have a scan tool to read datastream values would be great to monitor the readings from the speed sensors while driving, but you could check the sensors signal with a dvom on a hoist. Also i have seen a couple of mid to late 90's intrepids melt the connections inside the interior fuse panel on the drivers side, causing many erractic things to occur. Ensure all the fuses and panel inself is in tact. got to go for now, hope this will help, any more questions let me know.

Service manual


Free manuals can be hard to find, however most libraries have free online access subscriptions to most service manuals, you can get them free, but you have to go to the local branch to get it.
