200-4R Behind a 340 and Reid Bellhousing Build

Hi Guys, Contemplating this swap. I've had a 904 with Cheetah Turbo Action reverse manual valve body for years & I still like shifting manually.

Is the O/D just a position on the shifter, or does that also have an electric engage?
Thanks for any info you can provide.

Its a position on the shifter. The lock-up torque converter uses 12V to close open a solenoid to charge the lock up function. Lonnie at Extreme Automatics makes a manual valve body for the 200R4. He is second to none on building these transmissions and has great after sale support & customer service. I highly recommend talking and shopping with him.
