Most of the early minivans were available with a (rarely chosen) MT option, but I haven't seen one in a long time.
I think even the base Astro was available with a manual back around '85.
For sure the early Aerostar, Toyota Van, Previa, Caravan and Voyager, and the Mazda MPV offered a 5-speed MT in the early years.
I think the Dodge Caravan was available with the 2.4 and MT at least into the 3rd generation (1995 - 2000).
We had a '90 MPV with the SOHC 2.6 4-banger and 5-speed manual. Great van, a real pleasure to drive. Revved fairly high on the highway (about 2500 RPM @ 100 kph) but turned in good mileage.
