I got myself a "new" car (actually it's my first), a few days ago, It's a 1991 Ford Laser LX, with a 3-speed transmission (can't be very economic that way, but with a 1.6 engine I guess it doesn't matter too much), but last night I had this issue with it. All of a sudden it didn't want to go into second gear, I could tell because the engine was revving really high at 50km/h, then when I slowed down and accelerated again it went into 2nd and stopped over revving. Later that night I accelerated up to 80km/h and it wouldn't go into 3rd, it went in after I had to slow down for a roundabout and accelerated again.
A few Google searches seem to have a few people suggesting changing the transmission oil first, does anyone have some experience with this?
I think you should change the oil as people suggest. A friend of mine had the same problem in another car and changing the oil made it much better for him. Even if it doesn't fix your problem you can never go wrong with fresh new oil in it
I've heard numerous times though that if you check the fluid and it feels gritty, you shouldn't change it. Or something like that.
gritty trans fluid kind of sounds like metal shavings in the fluid, which is BAD.
HOWEVER, most of that grit you feel is the crap coming out of the dipstick tube itself when you pull it out.
not shifting can be a number of problems. usually if it's mechanical, you'll feel and hear it. otherwise, it's a solenoid problem. most automatic trannies use solenoids to determine when to shift rather than a combination of pressures from throttle and rpm.

does your gearbox whine at all?

I don't know how you can think gritty fluid is a good thing....
Lets put it this way. How would feel if you were having sex with lots of sand on your dick?

I can't tell if my gearbox is whining, my engine whines when it over revves though.
I managed to find my transmission fluid dip stick, seems the fluid is a brown colour, apparently it should be green or red if the fluid is still good. I'm going to drain and replace my transmission fluid

Because a clutch relies on friction, and a deteriorated wet clutch system(auto trans) would make your fluid gritty. Replacing your fluid with slippery fluid on a wet clutch that doesn't have enough grip left would make it slip really bad. Sex and transmissions are two completely different things.

I was actually referring to the many small parts in the gearbox that need to move freely, and don't like little bits of grit getting stuck in them and wearing everything out
Yeah I know, and it makes sense, there is just more to take into account (the clutch). If we were talking about pretty much any other oil lubricated contraption, you'd be In the right mind state. Just research 'gritty auto transmission fluid'. I'm possibly inaccurate in some of my info, i don't have personal experience with this, but it's a pretty common thing as far as i can tell.
>3 speed
>1.6
>doesn't go into 3rd
oh god

You're correct.
If the fluid is gritty, chances are, that grit is all that is keeping the tranny from slipping.
Change the oil and it will start slipping, since that grit isn't there to keep things gripping.
download, before changing the fluid, check the consistency. If it feels gritty, don't change it.

I'm more concerned about the transmission being cooled and lubricated correctly at the moment. I haven't had any slippage issues, if I had I'd be inclined to agree
Alright, changed the transmission fluid, and while I was at it, the oil.
No problems now, gears are changing flawlessly, and no slippage
That's what I thought
Also I laughed at the comments here: "Don't put new transmission oil in! It'll be worse!" wat
Nope, what i said was IF IT FEELS GRITTY, it will be worse. It didn't so it wasn't.

Learn to read.
Changing the tranny fluid can make it worse/make the transmission completely go, IF the fluid is gritty.
Dylan and I both said this
