    How do you physically separate the transmission from the engine for the 1986 Chevrolet Astro? Posted by Customer
    A:
    Position a transmission jack under the transmission, remove the transmission mount, crossmember, and brackets, and lower the transmission. Remove transmission-to-engine bolts, dipstick tube, cooler lines, transmission damper, and support. Support the engine with a floor jack, remove the starter motor, and ensure all wires are disconnected. Separate the transmission from the engine while holding the torque converter back against the transmission.
