Do we know what the typical GM 60 and 80 series transmissions do use for internal seals?
How many transmission fluids have a seal conditioner or sweller?
All ATFs have seal conditioners.
The stated Allison problem according to Transynd was not seal swelling, but hardening and cracking of Viton seals. Which seals had these problems were not stated.
