Help! Leak coming under transmission

[Chupapy]

Hey all,

Have found a leak coming under the transmission housing. Can see coolant leak from around the firewall but cant see exactly where its coming from. Has anyone had this happen? Car is a r33 gtr.

So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

Thanks for the reply mate. Well I really hope its a hose then not engine out job

Depending on the hose, sometimes engine out is the easiest option

Lots of people. Could be a lot of things like people have said. Either the heater hose/pipe, the turbo coolant return that wraps around the back of the engine, or a core plug. I have seen all three. If you want me to guess wildly though I would bet it's one of those hoses for the turbo coolant return. Or the brazing/welding for the Y- section has failed. Get a borescope down there to be 100% sure.
