Assembling A 4L70E-LS3 Combo

After inspecting our E-Rod LS3 for markings, casting numbers, and build plates, we install a flexplate on the engine and plug a torque converter into the transmission, then couple the tranny to the engine. Also applies to 4L60E and 4L65E transmissions (externally identical to our 4L70E), and most LS engines.

Parts Used:
Chevrolet 19421057 E-Rod LS3 Engine
Chevrolet 17804017 Torque Converter (2400 RPM Stall)
Chevrolet 19259117 Transmission Installation Kit
Jeg's 555-603026 4L70E Transmission (2 Wheel Drive)
