Ok after i got my newer motor ive been having problems with my transmission 5-speed... 1st gear keeps popping out when i go to accelerate.. 2-5th and reverse are fine sometimes if i hold it far up in first egar it will stay and i can go jsut fine but every other time it just glinds and pops out. the other day i held it in first and went to take off and felt the tranny funble and rock/shake... i got back to work and fluid was coming out of it so since then ive bought another tranny and i just put it in tonight and guess what... it still pops out of 1st gear wdf... Some 1 at work said that that could be from them not putting a pilot bearing in.... is that the deal or am i dealing with somethign else here?? im at a loss guys please help.

 

I would check the pilot bearing and the fork. Ive had one fork that wore completley through and would pop off the trans and could not shift. Sounds like something in the linkage is bent to me? Hit something and bend linkage underneath?

 

the linkage rod that comes from the sifter has a bend in it right?? right before it gets to the yolk on the tranny...

 

There is a slight bend in one I beleive.

 

All linkage is tight i took off the shifter boot and everything in there is tight i added another half qt of oil through the side plug and it locked it in reverse so i drained the half qt plus a little and it shifts fine but still pops out of 1st gear....Did i get lucky and buy a tranny just liek the one i just broke?? i cant believe this 1 has the same exact problems the 1 i just broke had before it broke.. it even chatters when im backing up liek the old 1 did..i need to know also exactly to what point to fill up the tranny with fluid.. im pouring it in through the speed sensor hole on top is there a depth i should be lookign for? right now its about 2 inches from the top...

 

I may be mistaken, but chattering (esp in reverse) is a sign of a cracked flywheel, greasy flywheel, bad clutch....


popping out of gear is no good; sounds like the trans wasn't taken care of.
Greeny got rid of his because he let the ISB go (if I recall correctly) and it started doing this (or was it that it woudn't go in gear?)

use the speed sensor as a dipstick. it should be at least partially covering the gear.

 

well its a brand new clutch just put it in about a month ago with barely any use at all.. i can see how my flywheel would be greasy because of when i lost fluid out of the housing when i broke the tranny but i would think the guys would of seen a cracked or broken flywheel when they put the clutch on but maybe not..and i believe that it is going into 1st gear because it rocks forward right before it grinds and pops out... my origional tranny had a messed up isb and it locked the left bank up but my fluid leval is definitly over the gear maybe ill drain some more out of it...could a bit too much mess anything up?

 

So from the countless searches ive been on looks like the newer tranny i just baught and installed is also bad.. has the same problems my last tranny had right before it broke..so looks like i get to call the place where i baught it from and try and get a refund or something because this isnt going to work... The only thing that seems strange to me is i never had a problem with any of this before i had my motor swap now ever since then ive had this same problem on 2 different trannys...

 

Sure, they probably would have SEEN it, but does that mean they would have done anything about it?...

 

Mke sure to check for any linkage adjustments. it sounds like its not in first gear all the way.

 

james your right i cant trust anybody i need to get in there and check it my self..
trbo ive checked the linkage to the tranny and all is right even the 2nd linkage arm that just holds it still is tight ima get under there in a little bit and put it in first gear then dissconnect the linkage and start it and see if it will stay in 1st if it does then im dealing with linkage if nto then its the tranny.. The only thing is when it pops otut of gear it feels as if it wasnt in there at all i mean the shifter does back off a little bit but it doesnt jerk or anything now it just quietly comes out of the #1 slot...

 

Just a question here i remember from when i first changed my transmission there was a what i thought was a dust shield that was sandwiched between the tranny and motor... i noticed that that was never put back on after the motor swap was done.. could this have anything to do with what im dealing with??

 

yea the rod is supposed to be bent some. how are your bushings, both on the shift rod, and the big rubber one on the support rod, and the one up inside the shifter bracket? if you aren't able to physically get the shifter rod to push far enough into gear that could cause it. maybe jack the car up on a hilland physically push it into 2nd (have someone else hold it to the left, then push the yoke yourself) and then lower the car and launch into 2nd gear... see if it stays in gear then. unless you're on a steep hill i doubt you can launch into 3rd gear, but if 2nd gear has been popping out that's a good enough test.

 

well see heres the thing when i actually put it into 1st gear ( which is the only 1 having this problem) it doesnt feel like much resistance when going into and out of gear..the shifter physically does go all the way into 1st but whhen i go to accelerate the car doesnt move at all, All you hear is a slight grinding and the shifter moves back toword N... Since the linkage pulls backword the same for 1st 3rd and 5th i dont understand why it works in 3rd and 5th but not 1st... anyway i have yet another tranny coming either tomorrow or thursday so ill try it again.. I really need to find that flywheel dust shield tho i wonder where i could get another 1..

 

Wait, what?

If that's not on the car, THAT IS YOUR PROBLEM!!

I just noticed that you said that was never put back on after the motor swap. You need to go back to that "mechanic" or "shop" or whoever is doing all this shoddy work for you and make them put that spacer/shield back on.

There's actually two - one full/circular one, and one half-moon one. Both of those must be present

 

theres 2?? i only thought there was 1 half moon on the bottem side but if there is 2 then ima really need to get to finding them... im doing the tranny swap my self and i have done it 4 times so its no biggy. The guy bringing the other tranny down for me to try is supposed to be bringing any or all dust shields with him so ill see what he's got.. my neighbor came over last night and told me he was having the same problem with his because the shields didnt go back on so ima get to finding them.. is there 1 that does on the top side of the trany 2 or what??

 

Yes, the full circle goes on under the flywheel. So it's a real ***** if you forget to put it on before putting the flywheel on.

Then you need the half moon one too

 

Orderd the shield today and a factory throw out bearing both came to 50 bucks so i was pretty suprised.. i also got the other tranny today so ima clean it up and get ready for the parts to arrive thursday. Hope it works this time!!

 

The plate i ordered is on back order and im not even sure if its the right 1...if the motor yard doesnt have it tomorrow when i call can i just measure the thickness of the top plate and shim the bottem 1 the same? or is it a different thickness?

 

I would wait for all the right parts on this reinstall, experience would have already told me that I need both pieces, I wouldn't do another swap without everything, good wrenching.

 

Thanks man im just anxious and tired of waiting... Getting somebody to actually do their job nowadays is practically impossible, i was on the phone with nissan 3 times this afternoon trying to get them to send a fax to my shop with the transmission brakedown so i can tell him what part it is and finally i got the fax and it ended up being the automatic brakedown.. wtf! Again i will try in the morning.

 

I had this issue with both the trannies that I rebuilt. The problem is the shift fork for 1st gear is worn. Or at times i've seen the shifter linkage bushing worn out, and that definatly will not put enough pressure to get it in gear. The tranny is definatly toast. Not bad rebuilding, but patience is virtue

 

Thx for the input guys but the place where i got the tranny from brought me down another tranny and i put it in 2 nights ago and.... !!! its perfect especially the new TOB from nissan man that thing is quiet lol but yea the bottem shim plate i was waiting for is on back order so i measured the top place and bought wasters the same thickness to place on 4 bottem bolts..So in the end all is good new tranny is doing perfectly as of right now.. Thanks all
