Transmission support brackets on 1990 Chevy Truck?
I know this question isn't quite "hot rod" related, but I know there are a lot of good mechanics here experienced in a wide variety of vehicles...
Long story short, we are installing a new engine in a neighbors truck., 1990 Chevy 1500 4x4,5.7L/auto trans. We got the new engine in today, bolted up the bell housing and torque converter, ect....and then realized we forgot to install the transmission support brackets. All they really are is a pair of bars that connect to the lower bell housing support and the motor mounts. We forgot to install the mounting plate that sits between the motor mounts and the engine block...
How critical are these? I've never seen them on any other vehicle I've worked on. They certainlly don't hold any of the weight of the transmission, nor do they hold the lower bell housing in place. Near as I can figure, they provide possibly some rotational support maybe? Are we going to be ok leaving them out? Or do we need to pull the motor and get them back in there>
