Does a 1995 buick riviera supercharged transmission interchange with a 1996 of the same make and model?

Unfortunate the 95 is an animal all by itself.

What transmission (used) should i look for ..for my ,,,95 super charged Riviera ,4t60 or t,65

I'm not familiar with 4t60 or t65. But I would suggest you get a trans from a 95 Riviera supercharged or when ordering a replacement make sure you provide the vin.

Can a 1998 Buick Riviera supercharger transmission going on Buick Riviera 1996 supercharger

The 95 & 96 Rivieras had 4T60E transmissions and are not interchangeable. The 95 had a Series I 3800 engine, so the trans is specific to that engine in your case and as mentioned above, a one-of. The 96 was also a one-of because it had the 3800 Series II motor, but a 4T60E trans with a vacuum modulator. The 97-99 had 4T65E-HD different transmissions that were electronically modulated and also not interchangeable with the 95 or the 96.
