Sup guys. Names Byron and I'm new to the forum here. I just bought a project car. A 91 cb7 coupe ex model. Has a 5spd tranny and stock f22a1 engine. I noticed from a cold start the car doesent seem to want to go in gear. I try to force it but that doesent seem to help either. If I turn the car off It will go in every gear without a problem. If I put it in gear, push in the clutch then start it, the car will move forward a bit when it starts up. Keep in mind this is only from a cold start. If I start it while its in gear and proceed to take off it will go but if I pull it out of gear then its hard to get it back in. For example if I start it in 2nd then drive with it in second for a few minutes it will go in every gear without a problem. Any suggestions would be greatly appreciated.

I would start with the clutch slave cylinder. That's a good starting point and there's a good chance that's the issue.
They are relatively cheap. About a 15 min job. Two 14mm bolts and a 10mm or 12mm line IIRC.
I imagine the clutch is engaging/disengaging near the floor as well. Meaning you have to push the clutch pedal all the way to the floor to shift or put in gear. And when you barely let up the car starts moving.
As far as it being a "cold start issue" I imagine it has to do with built up pressure rather than temp. If you pump the pedal before trying to put it in gear you might be able to put it in gear easier. If you try this and it works you have a clutch hydraulics issue. I'd start with the slave cylinder as I stated earlier.Last edited by H311RA151N; 04-25-2013, 07:07 AM.

Check the gear oil for consistency.
You may have gear oil mixed with water for some reason and it is turning into mayonnaise.
I had a VW type 3 which had exactly like that. It took overnight to drain what was in the gear box. Refilled it with proper gear oil and it was golden after that.
This CB7 is new to you. It is not bad of an idea to check and replace the gear oil, anyways.Last edited by oyajicool; 04-25-2013, 07:32 AM.A&P-IAComment

How does water get in the MTF? Just curious. I haven't directly heard of that before and when i have it was an extremely rare case. The suggestion sounds impractical and far fetched in this scenario but maybe I'm missing something.Originally posted by oyajicool View Post
We don't use gear oil BTW.
But checking the MTF wouldn't be a bad idea. I dont see how that could be your problem though. Just don't use gear oil if it needs any.

That's what mine did until one day I was late to work because the clutch pedal went to the floor and stayed. It was the slave or clutch master, I can't recall which. But it was an easy fix.Comment

I don't care of what you think of my post. I am telling it from my own experience on a car I bought in 1984.Originally posted by H311RA151N View Post
How the water got in the gear box? The car may have been a victim of flooding, or high water level on streets. Maybe, it was due to condensation. We get a lot of those here in FL, 11 months out of 12. Fuck, it may not have been water that contaminated the gear oil on that car. Whatever it was, the stuff was looking like mayonnaise when came out.
Prior to draining that stuff, the gear box was very hard to shift till temp comes up. Just like the OP is complaining.
If the slave cylinder is bad/leaking, most likely, the way the OP would complain would be "the clutch pedal is soft" or " the pedal goes to floor". That is the first thing he would notice. He may see wet slave cylinder if it is leaking. I read none of that in the opening. Maybe, the OP does not know much about the cars and doesn't know how to put it in words.
Why do you jump to recommend throwing a part at it. There could be more detailed information we could get from the OP to properly diagnose the issue.
Changing gear oil is considered as a preventive maintenance. Especially, when the car is new to him.
I used the term "gear oil" to differentiate it from oil that goes in the engine. MTF is a gear oil to me since it goes in a gear box. To select the correct gear oil/engine oil/fluids for the car is responsibility of the owner of the car, in the end.
But, hey, what do I know. I don't have that car in front of me. All I can do is to share some of information I have and try help others if I can.Last edited by oyajicool; 04-25-2013, 08:52 AM.A&P-IAComment

I didn't need that much of an explanation but ok.Originally posted by oyajicool View Post
Flooding was the only instance I've heard of water in the trans also. It was an auto but still. I've always thought it looked like a milk shake my self.
Hopefully if the OPs car has been flooded they would know. That info could be probable cause for alot of issues in the future as well.
Gear oil has been found in quite a few transmissions on here. That's why I noted that.
The probability of a faulty slave with the given symptoms is rather large. But I guess the OP will find out when they check. Sounds like a slave cylinder to me. I could be wrong. No need to criticize.

Thank you very much for leaving nice long PM on my page. I appreciate that. I am not that much in favor or fan of sending or receiving PM on public forums such as this one.
Relationship between two people is like looking at yourself in the mirror. If you think that I don't like you or whatever, it maybe due to what you have in your mind about me. So, please ask yourself that and keep it where it is.
You asked your question on this thread with quotation of my post. That is why I answered in my own words. Then you say, "I didn't need that much of an explanation but ok". So, which way is it you want? need answer/reply? or not?
When I saw your post about slave cylinder on this thread, I thought to myself that it has nothing or minimum to do with operating temp of the unit. But, I didn't disagree or questioned in public because of respect to the post itself and your effort. Instead, I have decided to share THE experience I had with my own car in the past, which had direct relationship between how the gear operated with different operating temperature. But, I guess you took my post as confrontation against yours. I don't know how you took it, but it's your problem.
My intention was to share my story. That is all there's to it.
Have a nice day.
Also let me reply here to the comment below.
Since I don't have any issue with any of members here, I decided to post my thought on the PM on here. on the other hand, if you don't like my post or how I behaved on the forum, you could have sent me a PM instead of making the post below t say it in public.

Yes you're right. The clutch is engaging/disengaging near the floor. Me and my buddy bled and adjusted the clutch. It was a lot better but after a few miles of driving it its back at the floor. Also there was gear oil in the tranny so we replaced it with 10w30 motor oil. For some reason third gear seems to pop out if I try to put it in gear normally. Or it rather won't go in unless I hold in third for a few seconds. But it confuses me because the tranny was just rebuilt in January and the previous owner spent 1300+. He gave me the receipt and parts that were replaced were(throw out bearing, engine rear main seal, engine oil pan gasket and transaxle assembly.) The grand total for that was $1343.83. Also the timing belt and water pump was replaced.Originally posted by H311RA151N View PostComment

Yea it had gear oil in it. We replaced it with motor oil 10w30. The gear oil smelled oh so sourOriginally posted by oyajicool View PostComment

Forgot to mentioning the slave is squeaking. So its the clutch. I know about cars but im new to manual tranny. Although im new I know how to drive manual.Originally posted by H311RA151N View PostI didn't need that much of an explanation but ok.

For the shifting issue try Genuine Honda MTF. That should help with the third gear issue. However I would change the slave cylinder if its leaking first and foremost, see where that gets you. If the clutch pedal got low, you adjusted it, got low again, then you have a clutch hydraulics issue.
Just to clarify, the clutch master cylinder is on the fire wall. The slave is on the front of the transmission below the starter. If either of those are leaking they need to be replaced.
Again, so many people find gear oil in their transmissions. Idk why but it seems many people are not aware that that's incorrect.
EDIT: When you change the slave or master, which ever one is leaking, you will need to readjust your pedal again.Last edited by H311RA151N; 04-25-2013, 11:56 PM.

I would agree that the clutch pedal should be adjusted.
Per the service manual the procedure is as follows.
- Loosen the locknut on the stop bolt and back off the bolt until it no longer touches the clutch pedal
- Loosen the lock nut on the push rod of the clutch master.
- Turn the push rod of the master in or out to get correct stroke and height of pedal
- Tighten the locknut on the push rod
- Turn the adjusting bolt until it contacts the clutch pedal, then another 1/4 to 1/2 turn.
- Then tighten the locknut on the adjusting bolt.
Stroke should be around 5.5 inches
Height to the floor behind the pedal should be about 8.25 inches
and the clutch should disengage 3.5" min to the floor
Also, one other thing to check, look at the rubber line - it runs from the top of the transmission to the passenger fender wall, if it looks wet, its bad.
Good luck!Comment
