All forklifts have an isolator valve in the drive system that stops the vehicle movement if the foot is on the brake
that area of control is where I would be looking at because if the valve is not allowed to neutralize properly then it stops movement or only allows partial movement

    Where do I look for that isolator valve ?

  • Bill Boyd Dec 04, 2016

    follow the hydraulic line from the master cylinder and there will be a "T" junction where it goes to the actuator as well as to the brakes
    if the master cylinder has not been service for some time the problem could be therewith a compensating port blocked resulting in the same effect

TCM Forklift model FCG25-3L will not start when i turn the key to the on postion u can hear the fuel coming out of the intake


Danger of hydro-lock or fuel in crankcase condition will occur. Do not start! Fuel pump relay should be interlocked with oil pressure sending unit. Is it diesel or gas? Is it Carb or fuel injection? Investigate before running engine. Check oil dipstick for presence of fuel in oil. Fire hazard also exist .Be careful.

2009 mazda 6. Spedometer lagging (goes up and down slowly or seems to stick at 0) RPM's working, seem to jolt up a little bit when trying to give car gas. Does not feel right when driving. Wheel on car...


Run the fault codes and check for TCM problem as the instruments are controlled from it. By the wheel I take it that you mean the steering wheel in which case check the power steering pump belt condition and tension.. Check oil level in steering reservoir.

1996 Geo metro, not automaticly shifting?


that is the TCM
the TCM transmission brain, needs to be scanned !
Do not overfill the trans, fill it using the instructions; do not guess.
so does Drive always work in 1st, gear car moves ok.
and reverse.,.

only fails to up shift in drive that it, ??? post symptoms more clearly
please...
there are like 50 bad symptoms possible on any A/t
1996 in the USA (are you or in Canada?)
is a major car redesign, here, OBD2 laws, et cetera.

and when they did that (some suzuki's) the TCM still is using old rules. old TCM retained, seem not on this car...

later they moved Mrs. TCM into the ECU box. and renamed it PCM.
that is the short history on most 96 cars made.

why not buy a used service manual on this car, off fleabay
and see all that uniqueness to this 96 car.

A metro is are really a GM modified, Suzuki SWIFT.
see hood sticker it states that clearly. (up under)
adding to the uniqueness of any 96 car the GEO mods.
i looked online for you.


it shows the M60 3speed trans
shows its controlled from the PCM (its integrated)
6 gear shift wires, that must work
2 wire VSS speed sensor (clean it ?)
2 shift solenoids.

ever heard of a scan tool?
any USA scan tool works on a USA car, 96, (98 in canada)
plug it in,
best is to driven and scan to see all errors. (2 persons dig?)
then see DTC errors, P07xx errors
the errors must be corrected. first.

recap.
1: check fuses.
2: check levels (not guessing,hot in park, read manual)
3: scan it with any obd2 scan tool made.

Transmission problem


Hi renjay, is your jeep trans an AW-4 or a 46RH? The simple things to check here without getting to the internals are as follows; check your oil level,filter etc. check the throttle linkage adjustment,check the trans shift adjustment also have the TCM tested, the TCM (transmission control module) used with the AW-4 has a self diagnostic program compatible with the DRB II scan tool.The tester will identify faults in the electrical control system it will help determine if the problem is electrical or mechanical, after this it tends to become internal and we can adress that issue if it arises,hope this helps,good luck and let me know how you make out or drop me a line if you have any questions,take care
