Type T-4 Trans Fluid Vendor?

[Magpie]

Does anyone know a vendor for the T-4 transmission fluid most new cars now use besides the factory? Ours (Toyota) charges almost $16.00 for a 1-gallon can.
Thanks!

I think your gonna have to stick with Toyota (or Lexus)......
I've never heard of anyone else offering T4.
Sorry.......
