Any oil on the Ground?? is something dripping??? is it a rebuilt trannie, or used, was the front seal changed. Ide start with,
Checking the trans pan gasket,
checking the bell housing for oil leaks, coming from the front seal.
check the dipstick tube seal
outputshaft seal
valve cover gaskets
intake gaskets.
trannie cooling lines.
Hose it down real good, and lay under it and watch....
