I just replaced the input shaft bearing on my 99 EX tranny, and there's a few problems with it after I've put it back in, some larger than others.

1. 5th gear will not engage. I can't shift to fifth gear not matter what I do. Yesterday, when I put the tranny in, I could go into reverse either. I've driven it about 25 miles since then, and now I can get it into reverse fine. It seems to have worked itself out. Will the same thing happen with the 5th gear problem? Will it realign itself and eventually work? Does it have something to do with the 3 set screws with the springs and the steel ***** at the end, because those caused me problems before with the tranny shifting at all?

2. When I shift it feels somewhat notchy, not very smooth. I don't have a short shifter, only ES poly bushings. At first it seemed like sometimes it was hard to even get into gear, but now it seems easier.

3. When I take off from a stop in first, the car kinda shakes foward. Almost feels like a mount to me for some reason. I don't know how else to explain it, it just kinda shakes for a second or two. But you can't feel it unless you're driving.

TIA for the advice, input, and help.

Maybe you dident put the shift forks toghter propperly? Also check the fluid, or possibly try GM Synco mesh. But that is a tuffy im not sure what to tell you man good luck!

 

Sounds like you didnt get the shift locks put back together correctly. Hate to say it but it's time to pull it back off and fix it. Check with BauleyCivic. He did the same thing.

 

Where, or maybe more appropriately, what are the shift locks? How hard is it going to be on the tranny to keep driving it? What do I need to look for when fixing it? Is it something to do with the shift fork assembly itself or the gears and synchros on the mainshaft? Sorry for all the questions. Thanks.

 

Remember those 3 poles that had to go up and down to shift gears? 5th and reverse are on one of them, and you didn't get it back into the little U shaped peice. Yes, its hard on the tranny if you're trying to shift into 5th or R and I can't imagine driving around with neither of those gears is easy.

 

not really sure what they're talkin about, but i would imagine that you have a synchronizer clutch hub assembly turned around backwards. ever heard of the double meshing assembly?? should you have performed this work??

I don't think so at all. There are three rods that are attached to the mainshaft and countershaft assemblies that are what changes the gears (sorry I don't know the technical terms, I just work on the junk). My guess is he didn't get the selector for 5th and reverse back into the hoop like it was supossed to and now he's locked out. Agian, I'm waiting on BauleyCivic to chime in here. He did this.

 

Part #7 (above) has to 'fit into' the U grooves of Parts #6, 7, and 3 (below).



Is this what you're talking about Ricey?

When I was putting my 99 Cx tranny back together, the whole gear cluster wouldn't even go in without Part #7 (above) being aligned with all 3 of the U grooves on the shift forks.

 

To my knowledge everything went back in correctly, and everything went back into the right slot. Since one of those forks is 5th and reverse, how come I have reverse but no 5th? It seems like maybe it's something not lining up on the mainshaft itself. Just ideas. Right now I don't know as there is much use in me taking it apart as I'm not really sure what to look for. Thanks for all the replies.

 

Does anyone have any pictures of the mainshaft that can show me exactly how everything should be put back together? The tranny is really smooth now, but I still don't have 5th gear. What should I look for when I take it apart? Thanks.

 

start with the basics first

check the mounts
check the clutch cable
make sure the tranny is aligned on the engineh correctly
check the fluid level

 

those are the detent ***** and interlock pins on the shift fork shafts. did you have any interlock pins layin around afterwards?

also, what the other guy said about possibly having a shift fork shaft turned around backwards, but it all boils down to probably needing to come back out. i know that sucks, but ya gotta do what ya gotta do

 

That's exactly what I'm talking about chris.

 

All the ***** and pins lined up when I put them back in, so I don't think a shift fork is turned around, but I could be wrong. Is it possible that some of the gears and synchros on the mainshaft are out of alignment? My plan is to take it back off and open it back up, and then use the shift lever on the outside of the tranny and play around with trying to shift into fifth and see if I can see what's wrong. This shouldn't be that hard of a thing to figure out should it?

 

I don't know if you'll be able to shift the tranny without the outter half on - it supports the shift forks as well as the shift detent bolts. I'm not gonna say it can't be done, but....

When you lifted the gear cluster out, did these items come off? I remember pulling the gear cluster out and **** moving around and me thinking "****, does this stuff have to aligned someway or another"....wasn't the case though.

 

Yes, all that **** did move around on me, and I thought the same thing. I think I remember being able to shift with the tranny split open, may not work if it were in the car that way and under load, but out of the car it seemed to work.
