Default 94 4L60E Transmission

Will a 5.3 LM7 bolt to a 94 4L60E Transmission or does it have to be OBD2??

It can bolt up with the right combo of flexplate and spacer,but the pcm cannot control it.

You can use it, it can be bolted together, choose a converter for the trans, then use a flat 4L80E flexplate with the 0.400" aluminum spacer.
Just tell whoever tunes your pcm so they can make it all work together. PWM was introduced mid-94, so chdck the front pump, behind the converter, before final assembly or the baseline tune.

I did exactly this, with the 4L60E from a 97 C2500 van with the L30 Vortec 305, which had the integrated bellhousing and PWM, my tuner guy had no trouble getting it to play nice with an '01 4.8L, and I was using the 2075-RPM-stall torque converter from a '99 L35 S-Blazer 4x4.
I won't recommend the guy I used, but since he managed it, others can also.
