Will any year transmission from a 90-93 integra work on a 90 b18a1 motor? I know the input shaft diameter on the 92-93 integra tranny is larger than 90-91 and the clutches do not cross, but are there any fitment issues related to the clearance hole in the end of the crankshaft that would cause problems with the larger shaft? Or are all the crankshafts machined with the same size hole regardless of the model year? If anyone had a b16a1 tranny they were willing to part with for less than an arm and a leg I wouldn't need an answer for this question. Such is life. Thanks for any help.

 

90-91 tegs have 24 splines on the output shaft...so do 88-91 b16 trans also....92 and up trans have a different amount of splines...

ok, regardless of splines, are the input shafts the same diameter on the end that goes into the crank on the engine, or is the 92-93 larger, therefore causing a clearance problem when the clutch is disengaged? Simply put, will any 90-93 transmission work with any 90-93 b18a engine, so long as you have the proper spline count on the clutch disk?
