    Red face 94 Chevy K1500 gushing transmission fluid from front seal

    I've got an awesome 1994 Chevy K1500 with a 350 turbo transmission that is leaking or should I say gushing transmission fluid from the front seal bad and I need some help!!!

    When I started my truck the other day, transmission fluid started pouring out the front seal.

    So we replaced the front seal, changed the transmission filter, flushed tranny & made sure the vent tube wasn't clogged. But when we started it, truck is still GUSHING fluid from the front seal???? We cant figure out why???

    Welcome to the club, it's good to have you aboard. I don't know anything about transmissions but if you post this in the tech section of this forum you will get better results.

    Welcome to the GMTC! I would post your issue in one of the tech forums with pics if you can and more description. Also add in how many miles it has. Your pump may be the problem or one of several things. It is odd that id only leaks while the truck is on no when it it sitting because it should at least drip from the leak while sitting.

    Why do you have a turbo 350 in a truck that should have a 4l60e? And my best guess on the leaking is that the front pump is toast.
