k so i have a 89 si trans that im having some problems with.i was driving the car and when i went to slow down i pressed the clutch peddle in and it started lunging real bad,this lunge is only happening when i press in the clutch.it also doesnt want to stay running in neutral almost like its still in gear it will move a little and stall unless i give it gas and let the clutch out.also it makes a awful wracket when in nuetral off of the clutch but if i press the clutch peddle in it goes away.im thinking its the input shaft bearing but i could use some more info because i dont know much about transmissions.thanks guys..the trans goes into all the gears like it should and comes out of gear with no problems so i wouldnt imagine it being anything with the gearset/shift forks

 

no one knows anything about d series trans anymore?

 

sounds right for input shaft bearing. but I suspect you also have a mechanical problem in the clutch as well though. either a clutch disc, plate, clutch fork, or cable.

 

im going to go ahead and swap everything out and see what happens.

 

k a little update.i decided to drive the car to my house so i can work on it.this only happens when taking off when you on the clutch after that i can shift fine with the clutch.the trans seem to not come fully out of gear in nuetral off the clutch.
