92 GMC vandura How do you take off transmission?

To remove the transmission from a 1992 GMC Vandura, first ensure the vehicle is securely lifted and supported. Disconnect the battery, then remove the driveshaft, exhaust, and any components obstructing access to the transmission. Unbolt the transmission from the engine and the crossmember, disconnect the shift linkage, and then carefully slide the transmission out of the bell housing. It may be helpful to use a transmission jack for support during this process.
