Title: Gearbox - VSS - ABS Controller/Pump/Modulator &nbs
Post by howke on Aug 31^st, 2011, 8:53am

Hi

My `97 24v is changing gears only when the O/D light is flashing and only to 3rd gear and to start the O/D flashing i must throttle the 1st gear to 4000 RPM :o to O/D light to start flashing or manually select 1st manually change to 2nd at about 2000rpm then at aprox 2000-2500rpm while driving in 2nd O/D light staarts to flash , then i put it in D and gearbox is changing gear from 1st-3rd by self like its supposed to do but no 4th gear .

Notice :
car was at mechanic shop for 1 year or so , in that time he changed defective ECU used was installed from same car same production year , some mechanic parts .
when i went to pick my car ABS light was flashing , speedo needle didnt work so i bought VSS and again speedo needle isnt working but ABS light is not flashing anymore but gearbox changes gear like i mentioned in start

My mechanic has told me to buy new(used) ABS Controller/Pump/Modulator as the old one is defective and the speedo meter will be operational and the gearbox will change the gears normaly .

So my question is there any known connection between Gearbox - VSS - ABS Controller/Pump/Modulator ... ok i know there is between Gearbox - VSS but what ABS Controller/Pump/Modulator has to do with changing the gears or VSS .

Sorry for my english , maybe it doesn't have sense .

cheers
ivan

Hi,

Your gearbox and speedo functions will not be affected by an ABS Fault.

ABS speeds are sensed by separate sensors on each wheel and not the VSS, as Gozz said I'd get a different mechanic.

Get him to scan it properly for gearbox codes, and see what comes up.

Did it have a NEW or USED VSS fitted, because Used ones are notorious for not working once removed and refitted, and it does sound lke a possible VSS problem.

HTH,

Regards Dave

The VSS is new , bought from Ford car dealer ... the problem is that mechanic is 150km away from where i live , and i kinda dont wanna drive there just for him to check my gearbox codes , i will have to find another one in my city where i can be beside him and watch what he is doing .

and he did something to the ABS light , cause when i went for my car 2nd time(and last time) the ABS light wasnt flashing .

i will try today after work to take a picture of the wires and parts that he changed , and post it ... meanwhile i will be hunting for new "good" mechanic .

is this original water cooling tank , cause today i checked water level and it was empty , had to fill 3-4 liters of destilled water , dont my car has water level sensor ???? anyway no light was flashing ... isnt sensor supposed to be on the tank , i didnt see it anywhere !!!

something was done in this fuse and relay box month ago when i went to check my a/c in work shop "specialized" only for a/c , they removed some relay that in their opinion didnt work and connect some wires directly

question regarding a/c : is it normal that when i turn on a/c the engine is becoming weaker , i mean rpm drops when at neutral and idle for aprox 200rpm then it gets back to 800rpm , but i notice then that engine is kinda weaker cause when i turn of the a/c while driving car goes better

A/C will use a fair bit of engine power, a good driver will notice this.

Some cars had water level sensor and some didn't, you need to find out where the leak is !!

Gearbox problem is very difficult to diagnose blind, especially one like you have.

You really need to get a scan done to tell us what codes are in the ECU then I can advise further.

There will definitely be gearbox related codes if the O/D lamp has been flashing

I agree, could be bad VSS is causing the flashing O/D light.

The flashing O/D light means the management computer thinks there is a fault with the gearbox. It then ceases to influence gear changes using the gearbox solenoid valves, so the gearbox is left to itself to perform the changes, that is probably why it is changing gears only when O/D is flashing, if VSS is not working computer assumes car is not moving and so will not change up out of first gear. I am just guessing mind you. ;D

By you revving it to 4,000 rpm and VSS still says car is "stationary" finally convinces the computer that gearbox is "faulty", hence flashing O/D.

Gear changing is very rough when O/D is flashing, since computer is not blanking the ignition to make the gear changes smoother.

As Dave says ABS is a completely separate issue, using different sensors. Flashing ABS light may just mean there is a problem with one of the wheel speed sensors, i.e. not working / start-up test failed, but I am guessing again.

PS: I think you lose 4th gear anyway if O/D flashing, i.e. "is not allowed", at least I think mine was like that when it used to do it, if I remember correctly.

PPS: I think first step is probably get a working VSS and go from there (?)

Was the ABS light flashing? It normally just stays on if there's a fault.

Do you have a cover for the battery/fusebox?

thanks for all replies so far

car was left yesterday at mechanic ... 20km far from my residence so its near me .... mechanic was introduced with the problems and whole situation my car been thru

i instructed him to start with the VSS and to put the speedo and km in working order , for start , just to see if that is causing the gearbox problems
i checked the gearbox fluid and it looks good to me , clear and reddish , no debris or any black particles

@Tompion
ABS light stayed on , not flashing
No cover for battery/fusebox as you can notice from picture ... will get one

can some1 point where are the draining holes are ... didnt menage to locate them ???

Title: Re: Gearbox - VSS - ABS Controller/Pump/Modulator

Yes are obscure, under the front ends of the fuse boxes I think (?)

Yes see here:

Hi all

Just to inform you that i am happy as a baby again

gearbox changing gears smoothly
changed the water tank ... it is not in tip top condotion but it doesnt leak

Dont know what he really did but it took him 3 days to fix the speedo and gearbox changing
VSS wasnt the issue with the gearbox changing gears but it was some bad wiring from the previous mechanic work.

Thanks again for all your advices.

cheers
ivan
