I've got a TM magna manual, however the gear selector now feels like theres no gearing left and just sits in neutral all the time, can't get it into any other gear. anyone else had a problem similar to this? or know of a good way to fix a problem like this?

Broken shift cables, slipping clutch, borked gearbox, broken driveshafts, etc. - could be anything.
You need to do some simple troubleshooting to narrow down the point of the problem.

if you can get to the gearshift cables
at the selectors and the gearbox
there are small adjustments you can make
also bushes may be worn


are the engine mounts ok not broken/soft or sagging

is the clutch working ok

ok, so more details now haha

clutch is fine, I can see where the shifter connects to the gearbox and when the shifter is moved so does the connection, but it won't seem to engage gear... thinking the gearbox is probably had it, but hoping not. only payed $150 for the car, but its only done 150,000ks on a new motor and its an SE

bushes appear ok at the gear box and the mounts are all good

its not the driveshaft, you can feel in the shifter its not right, theres nothing there. admittedly this gear box was abused, but surely it would last longer than two days?

Abused in what way? Probably ripped the diff to bits, or ripped the centre out of the clutch. You need to respect a geriatric car like this. lol Breaking a diff takes milliseconds, easy as.

Breaking something takes milliseconds.
Wearing something out takes years.

Option 1 : Junk it.
Option 2 : Fix it. Find the broken bit and replace it.

Your choice!

PS You need to be more specific in describing the problem. "It feels like there is nothing there" could mean someone has stolen your gearbox.

the motor is too perfect, and the car itself is pretty clean and straight. how abused? it was paddock bashed... but i don't think it could be either, clutch still feels nice and tight, and there is no gearing at all, its like something has jammed.... does anyone know what a first gen GB is worth?

Not much.

^^ well might have to find one in good nick and drop it in, respray it, lower it, get set of rims, elante bodykit, efi conversion, and I have my dream car :P

Gear links are worn so bad that even when it's in gear the stick moves as if it's in neutral. I have driven a first gen like that before.

If you push it in to the 1st position and release the clutch does the car move?

nah mate, nothing in any gear, can't even get the stick to where 2nd is ment to be or reverse, can't move the bloody thing unless I push it lol

my auto was $360 delivered to my door

cool, thanks very much, I'll give it a good clean up and post pics up soon!

Best guess it that the steel scroll pins
on the inside of the box holding the selectors shafts has broken

a cheap fix but the box has to be taken apart

trying to get a exploded view for

the gearbox internals should all ok if low in Kms
check a haynes or gregories repair manual
and look for the gearbox strip down
with pictures and instructions
I got mine from a library:eeek:

alright cool, thanks buddy :)

umm are both selctors moving at the gearbox when u move the shifter inside the car? unless both are moving a decent amount then it could be the internal cable still
trace the cables back a touch from the rods on the gearbox, at the clips securing the cables in place on the brackets still there if not it wont select
last, disconect the cables from the gearbox (split pin/clip, then washer then just slide the cable off, and move the selectors around a bit, see if it will select a gear that way if you cant then its in the box, if u can then its the cable or shifter

they both sort of just wobble a little in place, not really move as such...

Grab one of the selector levers on the gearbox and move it as far as it can go in one direction. Then start the car with the clutch down, and let it up slowly. If it wants to move, you know its a cable or gear lever problem inside the cabin.

H plate?

tried this, one of them is jammed in place, the other one moves 3 clicks tried starting it and as if in neutral still, looks like I'm up for a new box, if anyone knows anywhere in S.A. that install them cheap let me know...

Don't take the box out just yet. There is a good chance that it is something external that is causing the problem.

The TM uses the km164 box which has a diaphragm which operates the high or low range on the input shaft. When you select 5th gear, what is actually happening is the input shaft goes into high range. It is possible for the box to get stuck in between high and low ranges so that the gearbox always seems to be in neutral.

Some things to check include the diaphragm on the back of the gearbox, the select control valve, all the vacuum lines and 1 way valve, 5th gear switch on the gearbox, and also the control relay.

If you need help with any of this, let me know.
