Remove the pan and inspect for damage. Straighten or repair pan if possible, if not, purchase a new pan. Also purchase a new gasket and filter. Install new gasket dry. Do not use any sealant on new gasket. You don't want any sealer goo getting into the transmission. A quality gasket and a straight pan installed correctly doesn't require any sealant. Do not over tighten pan bolts. Refill with correct ATF.
If you are sure that it did not freeze and crack the block, Then the intake manifold gasket is leaking. That is a common problem with the vortec Chevy engines. You need to replace the gasket with a factory Chevy gasket from the dealer.
NO. You should NEVER use any type of sealant on the transmission pan.
where is it leaking from?
There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out between the transmission and engine block then you have a freeze plug leaking in the back of the engine, between the transmission and block. Must remove the transmission and flywheel to fix it.
If it's leaking transmission fluid, could be a bad pump seal. If it's leaking engine oil, could be a bad oil filter, leaking valve cover gasket, leaking intake manifold gasket, leaking oil pressure sender, leaking distributor gasket.
change ur rear differential gasket or ur transfer case is leaking
Remove transmission oil pan to access filter. Clean oil pan , replace oil, filter, and gasket
