So I'm swapping out my transmission cause mine came apart a few months back. I pulled a 5 speed out of an 88 civic and I'm trying to put it in my 91 crx si. I've gotten the old one out and now I'm trying to get the new one in but no matter what I do I just can't get the shaft into the clutch/flywheel assembly. It just refuses to go. I feel it slide into place but it will only go so far. I'm at my witts end. Any suggestions as far as what I can do to make it go into place

 

Did you remove the clutch kit at alall? If so you need an alignment tool to set it. If not, make sure it has space and the dowel pins line up. Once the input shaft slides on, you might have to wiggle the trans front to back to get the splines to match up.

 

U got to make sure the flywheel is in place. U dont need any alignmeent tool u can do that w ur fingers by toching over the presure plate trough the small gaps.

 

An '88 transmission won't fit on a '91 without also using the '88 flywheel/clutch assembly. The input shaft spline count is 21 on the '88 versus 20 for the '89-'91. If you need to get it back on the road quickly, stick an '86-'89 Accord clutch disc in there for the time being. That will work with the existing flywheel/pressure plate while allowing the transmission to bolt on.

 

Damn that sucks! I just put a new clutch on it when I did the engine swap not even 3000 miles ago. I'll go grab the one off the doner.

 

I just need the clutch right. I shouldn't need the flywheel should I? That would be fun to pull in the middle of the boneyard.

 

You need the flywheel as well. It will be different since the '88 clutch has a smaller surface area (190mm vs. 212mm) and the old pressure plate won't bolt up.

 

You can use the clutch off of an 86-89 accord an keep the 89-91 flywheel and pressure plate

 

So I went back to the boneyard this morning and pulled the clutch and pressure plate from the doner car. The clutch on the doner is almost new so I just pulled it. Silentdork818, your right the pressure plate and clutch are slightly smaller than what came off the 91 crx so I just kept the pressure plate from the crx and used the clutch from the 88. Yeah the clutch is about a 1/4 inch smaller than the flywheel and pressure plate but I dont see it being a problem. I did make sure the clutch fit on the shaft without binding or anything. I didnt have a lot of time to mess with it this morning but I did try to get it on and im still having the same problem. The input shaft just wont slid in when I need it to. I have the clutch disk lined up good, i can feel the end of the shaft slid into the hole but only up to the unsplined part of the shaft. Ill screw with it when I get home from work and see what I can come up with.

 

what motor are you running? and as far as the tranny issue they can just be a pain sometimes honestly if u got a d series motor and d series tranny u shouldnt have any problems... id just grab a few friends to help u line it up because wat looks like its matched up to us can be off on the vehicle just because of the way it sits. ive done 4 tranny swaps on d series now and they can just be a pain but just keep tryin

 

and dont use the 86 to 89 accord tranny. horrible idea

 

sorry 86 to 89 accord clutch*

 

Why is it a horrible idea? Have you ever used one?

 

Like i said I just used the clutch disk from the 88 and left the flywheel and pressure plate from the 91 CRX. I put a sohc zc in it and its a d series tranny but not the exact same one. Its not an si tranny but it is a 5 speed. The clutch disk a bit smaller than what its replacing but i dont forsee any issues but then again I may be wrong and I may be completely screwing up but it does fit so I guess well see. Thanks for the help everybody, I really do appreciate it more than you know. :-)

 

So I finally got the tranny back on but it just didnt seem at all right. I couldn't just slid it on and start the bolts. I wouldn't slid on all the way, it stoped about a half inch short of being flush. I had to start the bolds and tighten each one a little at a time and that pulled it flush against the engine but then the clutch didn't release when I hit the pedal. It didn't do anything. I adjusted all the slack out of it so I know that's not it. I put an axle in place and turned the engine from the harmonic ballancer bolt and the axle was turning as if it were in gear so I feel pretty sure everything lined up. I don't see why using the smaller clutch disk would cause the problem I'm having but I must assume that this must be the issue so I guess I'll be back at the boneyard tomorrow pulling the flywheel off the doner. I'd live to know why it didnt work.

 

So I'm convinced that using the smaller clutch disk isn't my issue. Even if the disk was missing I should still feel the spring effect of the pressure plate. Something else musta gone wrong. I'm just about to the point where I'm ready to try setting the clutch and pressure plate in place, install the transmission and then put the bolts in the pressure plate from the hole where the starter goes. I gotta do something to get this bitch on the road. Everyday it's off the road I'm getting 8 miles a gallon and I can't keep throwing money in my trucks fuel tank.

 

Well after 5 days of cursing I finally got the transmission on thank GOD! I haven't got it all back together yet but I did get the passenger side all put back together. I'm hoping I'll have it all buttoned up tomorrow. All I gotta do is put the linkage back on, install the driver side axle, put the passenger side suspension back together, reconnect hoses, sensors, switches, reinstall the dizzy and starter, and fill her back up with oil and she's ready to go, I hope! I guess well see how that clutch works out. The pedal feels good. It's not quite as stiff as it was but if it works I'm good with it. Only time will tell

 

Glad to hear you made it work. Go easy on that clutch, it may be more likely to slip since it isn't matched to the flywheel.

 

Well I got it all put back together. I'm a little worried tho cause when i get on the gas it starts making this really fast ticking sound but it's only when your in the gas pedal and I don't mean when it full throttle. It starts at about 1500 rpm and does it till you switch gears and then it starts again. Once you hit 3rd, 4th, and 5th its not so bad cause the rpms are down. Also it only does it when the car is moving. I can sit in neutral and rev the engine and it wont do it. I haven't really noticed any clutch slippage. For a car that's been sitting for well over a year it's not running to bad. The fuel is old and it wobbled like crazy till the flat spots drove back out to round. All and all I'm happy with it, I'm just really concerned about that clicking. Wish I knew what it is.

 

i use one with no issues.

check your axles.

 

It could be the passenger axle, I hope that's all it is. I replaced the driver side axle. It seems like the more I drive it the less it does it so maybe it'll work itself out. Could just be dry gears from the tranny sitting for God only knows how long...... I also noticed that after it gets to operating temperature it has a slight hesitation. When I hit the pedal it takes a second to react. It may just be the old fuel but I did put like 2 gallons of 93 octane in it and I drained all but a gallon or two out of the tank last week. I put the old gas in my truck and it ran like a crack ***** in a pair of 6 inch heels, nasty. It was just starting to get the first hint of that old gas smell. My check engine light is on but I often have issues with the tps so that's probably why. Usually when the tps throws a code it just wants to idle ruff. It prolly just needs a tune up, it has been sitting almost 2 years so well see. At least she's back on the road.
