Hello,
Yes, that PCM has the capability to run your 4L60E. In fact, that 896 PCM and a 4L60E trans were very common in Sierra and Silverado trucks in 1999. No separate TCM required and it should be easy to make that all work. I'm running that PCM and a 4L60E in my 70 El Camino, small world. The Dirty Dingo people also make a mount for that variant of PCM so that you don't have to use that hulking behemoth chunk of plastic GM used.
Are you going to remove all of the unnecessary wires from your donor harness?? Don't forget that you will need to get a few things tuned out and turned off in that 896 PCM before it can be used in your El Camino.
Startup and at temp Idle Raised 100rpm
PE Delay set to zero
Cat Overtemp Disabled
All EVAP, EGR, Fuel Sender, and Rear O2 codes deleted
Speedo and shift points corrected for current tire/gear
VATS turned off no relearn necessary

I have had my El Camino for a little over a year and having been describing its resurrection from the dead over on El Camino Central.

I have a 2000 Corvette engine going into a 1979 El Camino, with a 4L60E from a 1998 Camaro. Red/blue 411 PCM. I have modified the harness to have the same pinouts as the 1998 Camaro, and added the connectors for the 4L60E, and am using a cable throttle body from a Camaro. I don't have it running yet, but my plan is to get the PCM flashed to be a 1998 Camaro.
