727 TF info and assistance:

[Richard]

Need help on this. I have a79 Traveler that I am putting back together. 345, 4bbl TQ, 727 w/D20 tc. Need to know:

After sitting on my garage floor for about 30 years, I am getting the 727 TF ready to put back in. Issue: I had the TF rebuilt about that long ago, and have NEVER used it. It's just been sitting. I have ordered, and received the necessary external seals to replace (thanks IHPARTS) and need to know about the internals:

are there any "internal" seals that can/could have dried out, or am I good to go? I guess this is my biggest issues as I don't wish to have it rebuilt again just to change out some internal seals (if there are any). As I mentioned, the tranny has never been run and has been sitting on my garage floor.

Thanks for the help.

May want to check the Shift shaft seals and the trans pan gasket

well, you are correct!
I did order the two items above from IHPARTS in a seal kit. My biggest concern is the "innards". Took off the D20 transfer case, all looks good inside, no rust at all. Took off the end snout (the part that the drive shaft pops into, same. I am changing out the shift seals and I have a reusable pan gasket from IHPARTS. My biggest concert is the "innards".
