904 Transmission Fluid Recommendation

lol, I didn't think any one would remember the sperm whale oil.
Pepperidge Farms remembers .

Old slim jim pontiacs
HA !! The old Slim Jims , RotoMatics , TurboGlides , etc. , are such obscurities. I actually saw a Slim Jim at one of the shops I deliver parts to ;it was pulled from a '60 Bonneville according to its owner .

Now all the new stuff is better friction material, not old organic stuff. Any fluid will work. dextron3 is good, dextron4 is good, ford is good- the trans doesn't care anymore. It just wont's some lube to keep bands and clutches from sticking, and needs to run the valve body and converter.
That's something I'd never even considered : superior friction materials ! Good call :glasses7:.
