I recently put a new engine in my handme down 92 Sierra 1500. The "new" engine is from a 96 Tahoe which is an issue because the tahoe had a 4l60e. The engine harness is from the 96 so the connectors that go to the transmission are useless since the sierra has a 700r4. I want to know can this engine and transmission work properly together even. Also can the 700r4 tv cable work with the new vortec tbi. thanks for your time
