Whats it going to be estimated around cost to get a seal and a shaft put in a 5 speed gearbox its the s20 I took it out casue it pours oil out as fast as I can put it in and the shaft wobbles like crazy and insight would be very helpful

 

If the input shaft is that loose and there is oil poring out you are probably better off just replacing the trans. You could split the case and see how bad it is but if the bearing is bad enough to cause that bad of wobble and let oil by the case is probably destroyed too. Here is a howto on replacing the ISB http://www.d-series.org/forums/showthread.php?t=14079 and here is what your case probbly looks like on the inside http://www.d-series.org/forums/showthread.php?t=103104
