    Q:
    How do you remove and install a Manual transmission? Posted by Customer
    A:
    To remove the transmission, start by disconnecting the negative battery cable and removing the shift lever. Raise the vehicle and remove the driveshaft(s), parking brake cable, and any necessary exhaust components. On 4WD models, remove the skid plate and transfer case, and disconnect all electrical connectors. Disconnect the fuel lines and remove the clutch release cylinder or hydraulic line. Support the engine/transmission assembly with a jack and remove the transmission mount bolts, catalytic converter hanger, and support braces. Remove the cover plate from the clutch housing and secure the transmission to a jack. Remove the crossmember and transmission mount, and lower the engine/transmission assembly to detach the fuel line retaining clips. Remove the transmission-to-bell housing or transmission-to-engine bolts, and carefully slide the transmission out from under the vehicle. Inspect the clutch components and consider installing new ones. To install the transmission, first install the clutch components if necessary. Raise the transmission into position and slide it forward to engage the input shaft with the clutch plate hub. Install the transmission-to-engine or transmission-to-clutch housing bolts, and then install the crossmember and transmission mount. Remove the jacks supporting the transmission and engine, and reinstall any previously removed components. Verify all wires and hoses are reconnected and the transmission is filled with lubricant. Finally, connect the negative battery cable, road-test the vehicle, and check for leaks.
