Alright well I have a 95 GSR tranny that gave out on me and i plan on fixing it but need to know what could be wrong. I took it off my 95 Integra GSR and put a S4 tranny on my GSR. The GSR tranny before taking it off the engine, I would have it in any gear 1-5 and reverse and the car would not move an inch. I while back I suspected that the ISB might be bad. Could this cause the tranny not to engage any gear if the bearing is completly broken? I want to fix this tranny cuz i plan to swap it into my Coupe with a JDM B20B engine so i want to make sure what i need to replace and get straight to the source of the problem.

 

Anyone??? I just want to make sure that the ISB can cause the tranny to do that.

 

It would be either the diff, final drive ring gear, or a driveshaft. A bad input shaft bearing wouldn't cause the car not ot move unless it indirectly caused other damage.

 

what happened when you tried to drive the car? Take the tranny apart. If the car wont move then it will be obvious whats bad if you know what your doing.

 

Well i talked to some of the mechanics that go by work and they all said that a blown input shaft bearing will cause the counter shaft from engaging any gear or something like that and since i blew it racing i'm pretty confident that it could be that but i just need to know from some honda-tech pro's what's their experience is.

What happened was that i was racing againts my friends S2000 and well I knew the tranny was gonna go so after like maybe 4 good runs on my way home it just all of a sudden stopped accelerating. I popped it in every gear and nothing i would just see the rpm move up so i figured the input shaft bearing might of already just completly snapped. So when i swapped in the new S4 tranny when draining the oil off the gsr tranny i could see the oil dark and kind of metallic i'm guessing from the metal shavings. Well i'll start the tear down on the tranny friday but please any of you let me know if i'm right about it just being the input shaft bearing plus it also started to leak out into the clutch housing.

 

The input shaft bearing will try to stop the input shaft from moving due to heavy friction. Sounds to me like something got ground off.
