ok i have a 91 teg with a b20vtec with exdey stage 1 clutch stock flywheel. i had my stock 91 LS trans on the car worked fine no problems i just chaged over to my S1 b16 trans and the problem im having is when i press the clutch all gear go in smooth perfectly fine. i put the trans into first gear i let off the clutch to roll and i have a rough grinding noise.. idk.. wtf it is if i let the clutch all the way out IN GEAR the car WILL NOT stall it stays on the throw out bearing is good the axel is installed correctly i dont no what it is? maybe need a different clutch? please give me some input.

 

hahaah oh dear. Now you say your ls tranny was a 91 right? ok well 90-91 ls trannies are a little different from 92-93 trannies, u most likely have a 92-93 s1 tranny. The difference is the imput shaft. U have the clutch suited for the 90-91 imput shaft, rather that the 92-93 imput shaft. your gonna need a new clutch disc get the 92-93 cable tranny wich im preety sure is the same for the newer hydro b-series trannys.

 

agreed. different splines on the input shafts.

 

Wrong, If he had a 92-93 Tranny, the input shaft would NOT go into the clutch because it would have been too big and there is no way he could have mounted that tranny on the block.


as far as I know, the S1 LS/B16a tranny was only offered in 90-91 variations.

Either way, if he had a 92-93 tranny, it would NOT go into the clutch at all, this sounds like something wrong internally on the tranny, Good Luck.

 

Hmmm I stand corrected. This is correct. I was a lil' high when I made the first respond lol. Yes you probably have a problem in the diff area. You're obviously not getting power to the axles. I would have taken it apart.

 

damn im stumped. im sure the tranny is good to be honest, the guy i got it from was an older person real helpful even got in contact with the dude but u never no. im sure the throwout bearing is good if not wouldnt go into gear or ud hear that nasty sound when u press the clutch in . if the tranny it self was shot it wouldnt go into gear( goes into every gear smooth ) the only thing i can think is bad is the clutch but idk how my clutch goes bad within a day of a trans swap lol. im really stumped here.

 

i would contact the person about your tranny.

 

I did get incontact with him he said there isn't anything wrong with the trans that something eles is the problem. I never took the clutch off the block u think maybe the clutch is off aligment?

 

actually if everything your saying is correct. a clutch from a 90-91 cannot fit on a 92-93 tranny. the input shaft would be too big for the clutch to correctly fit on to. You should pull everything out and make sure that the clutch is fitting correctly and is aligned correctly

 

Pay Attention now, I've already stated this, THE S1 WAS NOT OFFERED IN 92-93.


I don't know what to tell you 90SiRex, if you mounted the tranny on the block as I stated above, you clearly do not have a 92-93 (stop telling him this bs, you are not helping).


If you got the tranny mounted on the block and all the bolts tightened down to where the tranny is sitting flush on the block, clearly it is NOT a 92-93, it would not go on at all if it was (to the people still yacking about 92-93, look up the specs and year usage for the Y1/J1/S1/A1/YS1).


It could be a number of things, the tranny could be damaged internally, your clutch could be damaged, your pressure plate could be damaged somehow, it could be a number of things, you need to drop it back out and inspect the tranny or take it to somebody who can for you, Just because the tranny goes into all the gears with the clutch disengaged doesn't mean you don't have a synchro / hub / slider / bearing issue with it engaged, like I said, I'm not going to guess, I'm in the middle of rebuilding 3 cable trannys myself, a j1, a y1 lsd, and an S1 LS, best of luck to you man, once again in regards to the 92-93 statements, THIS IS WRONG, please stop spreading false information.

 

I no the te hole 92 93 spline differenece im not paying attention to that. I jacked the car up yesterday after work I spun the wheel and the axel is indeed skipping theeth inside the tranny. its damged internaly I already contacted the old owner and he is indeed going to fix it just gota drop it again lol :\
and thanks for ur info dohccrxsi greaty app!!
for the record i have a s1 91 jdm b16 tranny off a xsi integra.

 

could be blown differential (internals / spider gears), I wouldn't rule out improper clearences on mainshaft / counter shaft either though if the tranny was rebuilt, good luck.
