Got this the cases seperated about an inch but can't get it apart any further, what am I doing wrong? this is a 4G Si Transmission on a civic. Can't figure this out. Trying to see what is worn for an overhaul. And no I haven't been able to find a manual yet to show me how, but I am trying.

 

there is a clip on the countershaft

you have to take a plug out of the side of the tranny with a socket wrench (w/ no socket on it) and then use O ring pliers or some screw drivers to pop the clip off

Thanks, I thought thats what it was, finaly got the clip to let loose, I did find a online shop manual on quickhonda.net. Now I can figure out whether to overhaul it or stuff it up the behind of the fellow that sold me this "PERFECTLY GOOD" transmission and one that is even worse. Said they were in his previous cars he wrecked and were perfect when he pulled them. Bet he got a laugh when I drove away with both of those pieces of junk., well I do know where he works and they were cheap enough to justify the price of an overhaul. $200 for both.

 

taking apart trannies = not fun

hehe

 

Of course now I am major pissed, every gear face is pitted except for the final drive, this thing is junk. Well I'm going to swap the final drive into my old DX trans that was quiet and return whats left to the idiot that sold me this garbage. And this was the "good" transmission the other one still in my car is louder than the engine. I think that is fair since both transmissions he sold me were garbage and thats a lot of hours of work for nothing. He owes me that much for shafting me.

pitted as in minor rust????

Won't hurt anything.

 

I loooooooooooooove taking apart trannies. It's my favorite thing. As long as I dont have to pull them out or put them back in... it's all good.

How fast can you split down a D tranny and have the gearsets out????

just under 6 minutes

 

after opening a tranny case about 20 times now (pulled the tranny from the car about 5 times), i'm pretty much at the same "skill level" as you...

virginia_dude, if you have any questions about the tranny let me know. i JUST put my tranny back together this past weekend, so lots of stuff is fresh in my mind.

 

THe pitting I am talking about is the kind of marring you get with a severely worn gear face. Not rust. a fairly heavy pile of magnetic metalic paste on the magnet. in fact the final drive is the only thing not worn. Haven't pulled the gears off of the countershaft yet to see if the bearing surfaces are hosed yet. Last time I've seen wear like this was on a 1970 Triupph GT6 transmission. And those were woefully inadiquate for that motor. This one and the one in my car now that sounds absolutly horrible both were supossed to have about 100,000 on them. My impression is yeah, maybe more like 300,000. Honda gears shouldn't be worn out that soon. Am I correct in stateing I can put the Si final drive in my DX case by using the DX bearings which were good, THat trans was absolutly quiet. I know the SI case has bigger bearings but was returning the two Si Transmissions back to the guy that sold the junk to me. and He knows what cases were with what he sold me. One I have apart was a '91 SL1. need to get a good one on the road quick and cheap. Damn sick and tired of wasting time with bad transmissions. I may just go buy a damn ZC trans but then I need new axels. I have a ZC engine in the car now.

once you pull the mainshaft and the countershaft, check to see if the diff is rubbing the clutch housing portion of the case. i think this might also be occuring...

in my tranny information missions, the 88-89 Si trannies have an 80mm differential bearing. this is different than the 88-89 dx/hf cases which are 72mm.

in 90-91, the Si differential is a 72mm like all dx/hf cases.

so if you have all 90 and up cases you'll be fine. otherwise you might have some parts that won't fit.

hth.

 

I think they are split between those years. I know the DX is an '89 and am real sure the first Si box is a '90 or '91. well I will try in the next couple days. In any case I got pissed and went out bought a ZC box from Noyan, USA, INC. Have it in the back seat of my car as we speak. Even got the inner joints with it. Off a real clean motor. got a real good deal on it since thats where I bought my motor and they know me. No crud got into this one it was sealed up good, with the intermediate shaft and both inner CV joints. Axels were cut with a torch. Now I ned to research exactly what axels are the best fit. I remember something about an Accord wagon axel on one side but need to check. But still want to pull the better Si Final drive between the two just in case I decide to do A hybrid ZC, but want to end up with a good Si Spare at least, a DX trans is no good to me.

 

And I am 99.9% sure my DX has a good gearset and bearings. So between that and 2 hosed Si boxes I can make 1 good one I hope. THe end spport bearings are nothing to change as long as shaft sizes aren't different. I would have more problems dealing with the needle bearings and such shims and thrust washers.

use the 90-93 teg axles for the ZC tranny. that is what i was using before i swapped in the civic quaife and had to go back to si axles.

the hybrid zc/si tranny is awesome. i got one and love it. the quaife makes it even better.

 

Well I am not going to hybrid the ZC box right away at least. When I have the countershaft for the Si boxes checked for being within spec then maybe. Don't want to ruin a good box with a worn final drive. Lookes like I may have trouble finding the guys who sold the junk to me, seems to have recently left his job so I have to rely on a message being passed on to him and him having integrity. Unless both of those work out I may be stuck with 2 pieces of junk. Maybe I'll get lucky and both final drives will be good and not worn out of spec. As far as a Quaife, I drool over those but the price is a bit rich for my blood with the type of driving I do. It would be nice and would helps some but is it worth spending that much money? Maybe not in my case. My car is decent but is not cherry. CAI and exhaust with a high flow CAT would give me more bang for the buck. Since my ZC is breathing though the stock DX airbox and DX exhaust system with a worn out cat right now. I don't race or Auto-X. But we can dream right , heh, heh. Well thanks for your input I do appreciate it. THis board is great for that. I was a honda NEWBIE 6 months ago and was able to do the ZC swap into a 4G DX hatch with no other help other than what I got from the members of this board. And I t worked the first time I cranked it over.

 

so the 90-93 Teg axwls are a perfect fit? I thought I remember hearing that at full lock in one direction the TEG axel can pop out of one side (passenger) if I remember right. Well I will be trying to get a set of rebuilt ones down at trak Auto tonight. Hope to get this in this weekend. The Si Box in the car now sounds like it has gravel in it. I am real paranoid about buying used stuff off of private individuals right now because of the guy that screwed me.

 

well hopefully everything goes ok for you.

the quaife is a very piece. i auto-x and plan to road race so that's why i got mine. for your case the CAI and exhaust might be the best bet. damn i still need a CAI for mine.

that is awesome. this board has a lot of information for people if they actually read it all.

i had the 90-93 teg axles for a while in my car and i didn't have any problems. i know i went to full lock to the left (at least) a good number of times. i am trying to think to the right, but i am unsure. i know i haven't heard anything bad about them with the ZC tranny.

i am the same way as i have heard numerous horror stories about private sales. just use this as a learning experience.

I think I have problems with the '93 TEG axels, seems my drivers side likes to pop out at full left lock with just the slightest touch of the gas, trashed the inner CV joint last night on the test drive. almost twisted off the CV BOOT. Have almost cretainly trashed the joint. Taking it back to trak Auto tonight, will say its defective. way take the next on apart but use the stock DX passenger side axel and just transfer the both of the new CV Joints to it since its about an inch or 2 longer and think that should resolve the short axel situation the passenger side appears to be fine.

 

since you've pulled your tranny so many times, is there a trick to disconnecting the speedo cable?

 

i didn't have any problems but i used the 90 teg axles. not sure about the intermediate shaft as i bought the car with the ZC in it. i just know for sure the axles were 90 teg ones.

i'm not sure if what you're gonna do will work, but i hope so for your sake.

 

there is a little clips that sits in a recess that holds the speedo cable in. if you pull back the rubber boot, you should be able to feel the clip. pull the clip out and the speedo cable comes right out.

 

well to my knowledge the parts book says the '90 thru '93 integra axels without ABS are the same. Since I havent taken the core back yet I have the original DX right side axel I could set along side the Left side TEG axel. Since my original drivers side axel came apart pulling it out, ( Boot not clamped real good) I was able to check against one of the inner ZC inner CVs that were still on the tranny I bought and the trick is to use the CV housing AND bearings both, the shaft the bearins ride are the same diameter and the axels itself looks the same diameter just a little bit longer. About 1 or 1.5 inches but no more. I could transfer the new boots and CV joints all together just have to buy new boot clamps. Somebody on a hybrid site said 2 right side Civic axels with TEG inner CVS are a perfect fit since they were a little longer. I would swap it all over if I did it since I think my outer CV's on my right side DX axel is a tad loose but not bad yet. the shaft isn't a wear item and if not bend or damaged it should be 100% fine. But if the stock TEG axels going to pop on me like that I have to do something about it.

 

in 90-91, the Si differential is a 72mm like all dx/hf cases.

not true - my '90 CRX Si transmission has 80mm bearings. I don't think that tranny differences like this can be determined by year, or serial # for that matter - rather something like Bone has on his page - the number in the casting near the filler plug. In general, the Si's and sedan EX's have the big bearing trannys. I've got a number of L3's around here....

As for the Si final drive swap into the DX tranny, you should be able to do that no problem, regardless of the diff. bearing sizes - it would just be a question of if you have to pull the ring gear off of the diff (due to bearing incompatability). Or, is the diff in the Si tranny hosed too?

 

As far as I can tell the Diff is good, pinion gears appear to be good without the face pitting the gears 1-5 have. Haven't taken the gears off the countershaft yet to have it checked for being in spec before I swap it. THe gears are shot in the Si and the DX works perfectly but what good is it with that final drive in it. Thats why I want to do this. Hard to find good Si gearboxes with under 200,000 miles in this part of the country. Besides I may just take one of the Si Final drives assuming they are both in tollerance and Hybrid my ZC trans and take the other with my DX box and make another good trans, to keep or sell. Since I woun't sell crap to others like the guy that stuck me with 2 bad Si Boxes.

when i was looking for a si case for my 89, i talked to 1 or 2 people who said they had 90-91 si cases. both measured the cases for me and said the bearing housing was 72mm, not 80mm like i needed. that is why i stated that...

it makes a lot more sense that the 88-91 si cases have the same diff bearing size.

thanks for the correction TJ.
