Okay... first of all i have had no experinces with trannies.

I just bought a 97 ITR JDM tranny and when I was moving it into the house i heard what sounded like pebbles inside of the tranny moving around.... Please tell me this is normal...

 

<<<< guessing its not normal.. hahah.. sorry just figured you wanted some kinda ansswer no matter what it is

 

sigh... another thing I just noticed is that I cannot turn the input shaft. Does anyone know what could be causing these problems?

 

Oh Kelvin...

 

probably because its JDM y0!

 

could it be some teeth on a toasted tranny? I don't like to assume the worst, but, I've heard a stang once take off from the line and he blew his tranny right then and there. It sounded like a small tinging sound much like pebbles.

 

If it's in gear it may be hard to turn the input shaft. Try using the shift rod (the part the shift linkage connects to) to put it in neutral. Also remember it has no oil in it, which will make it more difficult to turn.

I can tell you that something resembling the sound of pebbles rolling around is not normal. Since you have the trans out of the car you should open it and check for damaged/loose parts. It could be a million different things, but one thing's for sure: opening it and inspecting it is going to get you much further than speculation by people on this board.

 

If you can hear pebbles when the car idles, it might be the inputshaft bearing- Don't ask me how I know.

Thanks guys!

I've tried messing with shift linkage and I can only pull it out from the tranny. How do I select netural?

Bbasso how much does it cost to replace the mainshaft bearing? And how hard is to to do yourself?

Hopefully a friend of mine that is stopping by tonight can help me figure out what's wrong with this tranny.

 

Okay guys found out a couple of things.


First of all my friend hasn't worked on Honda's in a year or so and when he did he mostly did work on his H22.


I was able to put it into neutral and it does turn!!! How do you know what gear you are in btw with the shift rod?

My friend said that during shipment of the tranny it is possible that rocks or something could of gotten into the tranny case through the differntial?
(can anyone confirm this?)

I'd say it's pretty unlikely that anything got into the tranny durring shipment....

As far as knowing what gear your in, not that it really matters, but if you were using the shift linkage only, from neutral, first would be "left"(counter-clockwise) and "out"(away from the tranny), second would be "left" and "in"(toward the tranny), third would be center(no turn) and out, fourth center and in, fifth would be right(clockwise) and out, and reverse would be right and in. Assuming that the tranny is oriented the way it would be in the car.

As far as replacing mainshaft bearings, there is more than one mainshaft bearing, two on the top and one on the bottom if I recall correctly, the top most one usually being the one to go bad

There are closer to like ten bearings in your tranny that could have gone bad, and most will sound like marbles kicking around....so that really doesn't say much, there are also little ***** that hold the notches on the shift forks that could have also fallen into the tranny if one of the shift forks snapped, though that's extremely unlikely if you can shift though all the gears.

It could potentially be a lot of different things....I would say to take it apart, but if you don't know what you're doing...be careful.

Keep in mind, that in addition to taking apart the bolts on the bell housing, in order to seperate the bell housing from the base case, you need a snap ring pliers. On the top of the the tranny, there are a couple(2) rather large plugs, you want to remove the one that is closer to the bottom (assuming tranny is facing input shaft down) You should immediately see a snap ring around a bearing, and if it went bad a lot of metal shards as well....Once removing all the bolts, including the two bolts containing ball bearings and springs for the shift forks, and the TPS sensor if it came with one, pry the bell housing off while holding that snap ring open, and it should just pop off, keeping in mind that the HondaBond(silicon) that's holding it on is like glue and needs to be pried apart.

When you go to put it back togather, clean well the surfaces where the bell housing and base case make contact, make sure that when you put the housing back on you apply a sufficient amount of HondaBond(which you can buy from Honda), and that it slides on easily and that you don't force it, and remember you need to use the snap ring pliers to reseat the ring when putting it back togather(not as hard as it sounds). Then put the fork ***** back into the holes followed by the springs and then the bolts. Then the TPS if it came with one. That pretty much sums up a step by step...I'm sure I left some stuff out cause I havn't done it in a while, so you may wanna get someone else to confirm.

When you have the bell housing off....look at all the teeth on the syncros and gears...all the points should be sharp and not look rounded off, usually best to compare fifth gear with the rest, as it usually gets the least abuse.

On a side note, if more than one syncro is bad, it'll probably be cheaper to go buy another tranny....

Good luck.....sorry for the novel guys!!!

Later,
Aj

 

Yes, that was a novel. However, that novel was a very useful and informative post.

One correction; the sensor in the trans is the VSS (Vehicle Speed Sensor), not the TPS. Acronyms are easy to mix up and it didn't take away from the value of the post.

Anyway, going back to what the original post said, that it sounded like marbles in the tranny when he moved it around. He also mentioned that at this time he could not turn the input shaft. These two points pretty much negate any possibility of the problem being a bad bearing in the transmission.

I'm sticking to my guns.. something is broken or loose inside the transmission and is floating around. There are two differential holes (one for each axle) and the hole for the VSS. Stuff could be dropped in any of these holes as your friend suggests, but I'd call that a long shot.

So.. spare us the suspense.. follow AJ's instructions (or get a factory service manual, which will help you a lot) and open that sucker.

Good luck,

Justin

 

thank you all.

aaj23- I really appreciate you writing out all of that, I know its gonna take a lot of time an effort to get this working but I'm gonna try to make the best of a crappy situation.

madslackin-I actually am now able to turn the input shaft ever since I figured out how to get the tranny into neutral.

seeing as how I don't have any experince with opening a tranny I've made a thread in hopes that someone in the Washington/Oregon area will be able to help me out. https://honda-tech.com/zerothread?id=524798

Hahahah....right.....vss, sorry....I was studying for database communications for like 8 hours before I wrote that post last night, I guess my brain was fried!!!

 

Just to clarify..... I know you can turn the input shaft now. The _original_ post said you could not and that you were hearing noises just from picking up and moving the transmission.

Good luck with the trans.
