block and heads are the same but not the computers
YES they are the same.
the 1996 and 1997 are the same and would not work in your 2000 straight from GM
the best way to answer this is to check the Vin if the 8th digit is a W or Z on both then more then likely they will match up since 95 was the first year of the new body styling on s-10 blazers it is very likely that they will even have the same connectors
If they have the same part number, yes.
If they have the same part number, yes.
mounted next to the ing coil on the same bracket
No. The 2001 TrailBlazer was simply a trim package for the Blazer, which used an electronically controlled 4L60E transmission. The 1992 pickup would have a mechanical 4L60 transmission.
No. They had CPI induction engines indicated by a "W" on the vin., and TBI indicated by a "Z" on the vin. 2x4s and 4x4s have diffrent oil pans.
You add fluid the same place you check the fluid level.
