Removing Transmission
« on: October 31, 2016, 03:47:19 pm »
I have a 85 Chevy c10 and I am wanting to change the stall converter. This is probably a stupid question, but can the transmission be removed and reinstalled with the engine still in the truck. Can you drop the transmission from underneath the truck? Thanks.

To clarify yes, but support the engine from the rear as well.

Most manual transmission trucks have an engine support at the rear of the engine that fully supports the engine whether the transmission is installed or not.  However, most automatic transmissions utilize a mount at the back of the transmission so that if you pull the transmission the engine is not fully supported (only the front engine mounts are supporting it), so that you have to provide temporary support to the back of the engine while the transmission is out.

If you have an automatic transmission you will need to support the back of the engine while the transmission is removed.  I usually do this with a block of lumber across the bottom of the pan and a jack stand or bottle jack.  If you use a jack, make sure that it is in good working order and will not bleed off pressure under a load.  The stick of lumber across the pan is to spread the load and prevent from crushing the pan.
