Weird noise when engaging gears

[Schwebe101]

Hey guys I've searched around for a bit and didn't find an exact answer to my problem I am having. I am guessing it could have something to do with my clutch but i would like for someone to confirm this. What is happening is when I first start my car up in the mornings and go to put it in reverse it feels like it doesn't go all the way in. It feels like its about halfway in and it wont move any more. Then as I let the clutch out there is a spinning noise. Well its either a spinning or a grinding. Sounds more like a spinning to me but I could be wrong and the car doesn't move. So I have to let the clutch back out and then put it back in and keep repeating until it goes it to gear. It has done this to me while trying to go into first and reverse. Any idea whats going on here guys?

Reverse has no syncros, so you need to let the clutch out more slowly, so the collar has time to slip over the gear.

Just out of curiosity, does that apply to the trannies on the 4G63 cars too?

But when I'm sitting there and just try to put reverse into gear it wont go all the way. I can feel it. Its only going like half way in

Some yes. Which transmission did you have in mind? EDIT: Basically all of them really. Some have a type of a brake on the end of the case that helps with reverse, but it's not really a syncro.

So you let the clutch out really slowly, and when it begins to engage, the gear will fall the rest of the way into place. Do you want me to type it more slowly?

No, I understand what you are saying. But it normally works just fine, and why would it do it for first gear aswell?

An early 91 awd tranny. My guess is that I don't have a synchro because I have to do exactly that. OR I put it in reverse, go back to neutral and reverse again and it usually goes right in.

That's the same W5M33 that I have in my car. It's not really a syncro, but there is a reverse brake, and a reverse brake cone on the end cover of the case. According to the service manual, it was an optional part, but both of my W5M33s have it.

It's not really a syncro, but it will stop a spinning main shaft so you don't get that grinding sound when you first try to engage the gear.

A KM206 from a NA 4g63 1g has nothing, therefore you may need to stick the car in a different gear to stop the spinning, then drop it into reverse.

Would a shot syncro cause this to happen to first gear? Or is that not a possibility. Sorry not transmission smart at all.

Absolutely.

 

[Schwebe101]

Absolutely.

Well I'm guessing thats it then...Its always when Im at a stop and try putting it in first I have to let off the clutch and back on several times before it will fully go into first. When one syncro goes out does it normally mean more are to come? And where do you go from a dead syncro? How much does it cost to replace

 

[undefined0000]

While this synchro talk is going, I've got one more question, for the OP too.

OP, does yours do this at a stop or while moving for first gear? I Have to press really hard while moving and on the clutch to get back into first, it engages fine when going REALLY slow or completely stopped. Same issue or no? Shot synchro?

Mine does this mostly when stopped but I have had the problem where I will be trying to shift into 1st while moving and it happens to do it. I rarely shift into 1st while moving though.

I'll give you an old trick. Go to first gear then second gear then to reverse. I always do in anybody my cars 1,2, 1,2 R. Helps out alot and doesn't grind

It could be, or it could be lack of lubrication, or loose shifter linkages. I would't rule anything out without checking it.

Shot syncros usually means the car had had a rough life of high RPM shifts, or that someone who can't drive stick was using it for a period of time. It's really hard to predict which ones need to be replaced without pulling out the gearset and measuring the syncros. Generally speaking, the syncros could last several hundred thousand miles, or could be worn down in a week.

Prices may vary.

EDIT: It will be hard to put in first while moving, that's just how they are. Perfect syncros will make it easier, but it will be a little difficult to put it in first while moving. It's one of those things that puts undue stress on the syncros. You are actually using the syncro to acellerate the gearset instead of slow it down. Technically more work.

EDIT: For the nitpickers: Technically you would be using the syncro to acellerate the clutch disk faster than the engine RPM, instead of to decellerate the gearset.

I have been losing tranny fluid from an axel seal and I have been trying to keep it filled up until I can replace it. I recently replaced my other side. If its a little low would it do this then?

 

[Colt4G63 also]

What kind of fluid have you been putting in it?

 

[gst96spyderman]

Have you been launching the talon prior to the problem? If so, your syncro for 1st gear might be grinding and causing this... Let me clarify, reverse to first, or dry shifting?speed shifting? Maybe 7800rpm quick shifts? This can quicklylead to problems stated above

 

[Schwebe101]

Sorry for taking a bit to get back with you guys. And I am using Atf 4 in my tranny. Thats what I read to use on here. And I have launched it at about 3k RPM 2-3 times but thats it. Nothing else stupid, never shift above 6k rpm. I know its a 420a not a race car haha..
