transmission interchange 94 into 97?

[chad]

Can anyone tell me if a 1994 4L60E transmission will fit into a 1997 Chevy Blazer?
I know at about 1995 1/2 It became OBD2 does this matter?
I also think there was a bolt on belhousing or something that started around the same year.
Any help is greatly appreciated.

Bellhousing should be the same if the trannys are both from 4.3L or a SBC motor. 60* V6's like the 2.8/3.1/3.4 are a different bellhousing.

Im not 100% right now on the PCM/ECM connections. Maybe someone else has that info.

I found this answer in another thread off a different forum/group.

Re: interchange for transmission for s 10 blazer 97 model
I can for sure tell you that based on year it will not fit/interchange. The '94 had different electronics/setup, also the '97 has physically a different transmission case. The '96 and up were two piece cases, with the bellhousing one piece, and the transmission being the second piece.

Just for the record, the '95's were different, and pretty much unique to that year, as the operation(PWM function etc) were pretty much used in that year only. The mid '92 to '94 4L60E were all the same, pretty much
