Hello , I have a 64 c10 with 350 and the 350 turbo transmission with an drive line extension. It's been leaking ( slow drip) we replaced gasket seal where it bolts to trans ( tried a few different gaskets. The guy at the shop replaced the seal up by the front u joint, still got that drip. A transmission guy looked at it and did not see any cracks in the collar. ( may could be a hairline crack)
Has any one else had this issue or can provide and ideas to help with the drip?
I may buy new collar but not sure if that will fix the issue
