TURBO 400 TRANS FLUID?

[dariel]

Since this is a drag race car i will ask here.Which transmission fluid would you guys recommend.This is for a turbo 400 transmission attached to a low 11 sec 3.8 liter grand national.I was thinking redline but would like your input. thanks

Dariel I have Amsoil ATF in my transmission now, it shifts better than when I used Redline or Mobil 1 transmission fluid, but here is where it gets interesting I cannot give all the credit to Amsoil ATF because I recently did an Auto-Rx cleaning in my transmission before putting in Amsoil ATF, the transmission I have is a Turbo 350, so any of the above transmission fluids would be fine, I have read a lot about transmission fluids on this board, so you will get a lot of opinions, I am not going to tell you which one you have to use but it would be a good idea to read all the posts on transmission fluid, hope this helps out.

For crisp shifts, you want to use a type F fluid, or use a shift mod kit with plain old DexIII.
