MSD Atomic Transmission Controller for GM 4 speed transmission
Asking $800.00
I purchased this several years ago for a project and ended up going a different direction. The harness is specific for the GM 4L60e but can also be used on the 4L65/70 transmissions. This controller can be used on the 4L80e but you must purchase a different harness for that transmission.

Does that have provision for paddle shifters?

Re: MSD Atomic Transmission Controller for GM 4 speed transmission
I think so. The instructions say it supports manual mode with a bump up and a bump down. I couldn’t say if that is compatible with tap shift switches. It seems like it’s just a ground switch for the up/down shift signal on each circuit.
