Tremec 5 speed speedometer cable leak.

I recently had a TKX put into my Challenger. After the first drive I have a small leak at the speedometer cable. I called SST and didn't get much help. Their suggestion was to take it apart and grease the inside real good around the cable. Has anyone else had the issue? And did you figure out a fix? I see Bowler trans makes a double o ring adapter. But that's only for GM type screw on speedometer cables. Thanks

Just google Tremec speedometer cable leaks. Way back there was a bulletin that described it and it had to do with packing it with grease and o-ring placement as I recall.
