What problems are you having with the Powerglide?

if nobody responds, maybe check with the c1 Corvette owners and see if they have a recommendation.

My friend has a 54 convertible  with powerglide.  She said it is leaking a lot of fluid and wanted to have seals and gaskets replaced.

@mario-briseno As a club member, you can use the Member Roster (link under Rosters at the top of the page) to search for other club members in her area. They would likely know many of the shops in that area. Mine was rebuilt by a shop in Wichita but that won't help her. I also did an internet search of transmission shops in your area. There are several. A few phone calls might help to determine if they have PG experience.
