ggdad1951 Posted June 6, 2019 Report Share Posted June 6, 2019 My 4 speed was a fresh rebuild with all new seals and such and it wept day 2 after filling. I Think sometimes it's the way the truck gods want to keep the rust at bay on these old boys. Quote Link to comment Share on other sites More sharing options...
Dozerman51 Posted June 6, 2019 Report Share Posted June 6, 2019 Did you use Permatex 2 or similar on both sides of the gasket before installation? Another trick is to apply a small bead around the the outer edge of an oil seal before installation. On splined yokes etc I apply Permatex#2 on the splines before Installation as gear oil can work it’s way through the splines and leak through the washer and retaining nut. Half the fun is trying to have a 100% leak free vehicle. LOL. Quote Link to comment Share on other sites More sharing options...
TFC Posted June 8, 2019 Report Share Posted June 8, 2019 Had the same issue with my 52 B3B 3 speed transmission, shafts were leaking/weeping at both ends(front and back). For the back I made a cover(brass "box" soldered together) and rubber gasket. For the front I made a shim/gasket that covered the entire mating surface of the trans to flywheel housing from 5 mil brass shim stock, the brass extends below the mating surface to cover the area where the shaft is uncovered, during assembly a used some RTV in the area of the shaft. No leaks, yet... 2 Quote Link to comment Share on other sites More sharing options...
Fernando Mendes Posted June 11, 2019 Report Share Posted June 11, 2019 It would be this gasket? Quote Link to comment Share on other sites More sharing options...
