All, looking for some suggestions....

I recently installed a new (rebuilt) TH350 in my 29 and have been unable to isolate the source of a leak at the pan. I have replaced the gasket and set the bolts to spec and still have a leak? Any ideas?

o No apparent housing cracks
o Cleaned gasket mating surfaces
o New OEM gasket
o Bolts toqured to 13 foot pounds
o Gasket installed dry per spec
