Identify this transmission numbers stamped on passenger side of case are 3TAD310H can you help. Pulled out of 94 S10 blazer 4.3l vortec 4x4. bought a used one from same year and they don't match.

SOURCE: 94 blazer s10 4l60e and the 94 fullsize blazer

Installing the full-size Blazer trans into the S-10 would be safer. As long as they came off of the same size engine then yes, they will interchange. But.... the trans off of the S-10 is not built as strong as the trans for the full-sized Blazer, clutch capacity is less, band servo may have smaller apply area, and torque convertor stall speed may different enough to set a "code". Towing capability would be compromised. I have no idea what you meant by the "bolt for the plate".

SOURCE: gas gauge wont work

Pegged full or empty?

SOURCE: I have a 94 S10 Blazer 4x4 and a 94 S10 Blazer 4x4. Both are automatic transmissions and have the same size motor. Will the 94 ****** work in the 97?

yes

SOURCE: transfer case motor for push button 4x4

i have a 1993 blazer 4.3 w code 4x4 with a 4L60 E . my truck wouldn;t go in 4 hi or low. so i changed the transfer case motor and it works fine now. If you turn the ignition key to on but not crank the engine and open the driver door and push 4 hi button, you should hear the transfer case motor cycle for 3 or 4 seconds every time you push button and the light will flash until it goes in 4wd If the 4 hi button light doesn't flash during cycle then it could be a bad switch. if the transfer case motor won't cycle it could be a fuse or a bad transfer case motor . Hope this answers your question.
