GT500 tranny leaking

[Scottmain54]

Hi all. My 68 GT500 will occasionally leak out lots of fluid while sitting in the garage. I think the front seal is bad and am soliciting info to find a good shop in the Daytona beach region. It's been decade's since it was overhauled. Has anyone had a good experience with transmission work done around Daytona Beach?  Anyone to avoid?  Thanks

    I would advise a sum of diagnostic observation before any disassembly in order to attempt to determine where the leakage might actually be emanating from. 

    Yes, the front input shaft seal could be an issue, but the fluid level (at rest) is normally below this position, so any leakage being presented post a duration of non-usage would have had to accumulate for an interval somewhere else before dropping to the floor.   

    Scott.

C6 automatic or 4spd?

C6 automatic or 4spd?

Good question.
  If it is an automatic, don't rule out the dipstick tube "O" ring. Way easier to fix.

I had a C4 that would occasionally leak a bunch of fluid, most of the time it wouldn't leak much.  Turned out to be a worn shift shaft.

I have also found that if you have to persuade the dipstick mounting tab to line up, it can cause the O-ring to leak.

C6 when it sits can leak at dipstick o ring or servo lever plug inside the bellhousing.
The early style servo ball was the worst.

On C4 and C6 auto transmissions a leaking shift shaft seal is a very common problem

Another possible problem may be torque converter leak back. Especially if over filled. I know my 500 will leak a fair amount when it sits for a longer period of time, seems the transmission pan gets too full and out she comes around the side linkage! I solved my issue by running tranny with fluid down a bit. Falls into that category of " it worked for me "
