Can only be that the clutch disc is either sticking to the flywheel due to contamination, or it`s not adjusted correctly and so not releasing fully (there`s no synchro on reverse, so if the teeth are moving they won`t engage). I`d check the adjustment as a first step. Nothing wrong with the gearbox, but I`d stop the engine to put in reverse while you get it sorted as it won`t do the teeth any good.

ok thank you for the reply and how would i adjust it?
The clutch does bite rather high, but doesn't slip.

thanks

I'm sure that Steve will give a better reply, but there is info on clutch adjustment from this site's very own service/jobs page, here -

Sorry to tag onto your topic but it is sort of linked, My type 9 is harder to get in gear when car is run from cold, after a couple of miles all is quite smooth, is this a synchro problem starting or oil viscosity problem as it is thinner when warmer

Hi Mark. To me that definitely sounds like it may be worth looking at the oil. Take a look at this info from this site's very own how to section, specifically mentions cold gear changing -

I have the same problem with mine...I think its because the clutch is on its last legs. However I have found that if you select first gear before you put it into reverse that will stop it grinding.

Just give it a try , it works for me so it might work for you. Cheers Alex

That does sound like the plate`s sticking. When you put it in 1st first, it`s making the disc `stand still` and it will then go into reverse.

I can't really add anything to this re the clutch - that seems to be what was causing your problems. Regarding gearbox fluid, buy a cheap oil suction pump with a long flexible hose, and get as much into the 'box as you can, and suck the old stuff out. If you poke at different angles you keep getting more and more out each attempt. I can get all but the last quarter of a pint out that way. You'll find the old oil is really black, thick, gloopy and generally nasty.

Now for the re-fill... Some people recommend filling a manual box with ATF to ease cold shifting, however what I can tell you is this: It's a manual transmission, which Ford originally specified conventional gear-oil for... and it was filled with conventional gear oil from new and ran perfectly for 30 years and tens of thousands of miles on it. New manual gearbox oil will improve it like you wouldn't believe it. I just bung Castrol Universal 75w/90 GL4/GL5 in everything - the gearbox, diff... it works wonders and encompasses the original viscosity range Ford specified. Half the people claiming such a big improvement with ATF are probably seeing more of an improvement from the fact they're simply using fresh oil.

There is no special procedure for refilling the box - just pour in through the hole you sucked it out from, and when it starts p*ssing out, you've got enough in. Some people even try to overfill their gearboxes by having the car on a slant. I can't recommend it, but several people swear by it. Just make sure it's topped up to the fill hole.

FYI the fill plugs on the diff and gearbox use a weird key - one's square, the other's triangular or hex or something, I can't remember. Have a look and get the correct socket from any motorfactors.

Last but not least, don't put additives in the oil. I put some Wynns/STP/whatever goo in my gearbox and it actually caused an "old bus" or "mini" type of whine until I sucked out the oil and replaced with fresh.

Whenever I replace a box I always use ATF and I always slightly overfill it.

Ignore everything I just said. If Martin says ATF is OK I'm putting it in next time the mood takes me to change it.

Any particular flavour of ATF? Just the bog-standard stuff you'd put in the C3 transmission?

I can't remember which way round either, but one is square and one is hex. I bought the 'keys' from my local car shop. However, for the square one you can just use a 3/8" socket wrench.

Hi All,
Square hole for the axle, hex for the gearbox.
