Greetings,

Can you tell me which type of transmission oil would be best to use?

Thanks,
Gene

Which car and transmission?

I assume it's a '54 Pacific, so it has the Ultrmatic. Type F is the type most often recommended as a good replacement to the original type A that was specified. I use type F in my '54 Panama and it works great.

It's the Pacific. It's the transmission with the fill port that can only be accessed underneath the car.

As mentioned Type F works well. As far as which brand, I have been using Pennzoil, primarily because it was readily available at NAPA and Walmart. I might change if I do some research and find a reason to.



I thought the filler had been relocated to under the hood in '54?? Maybe early models still had it underneath, like my '53??

Not until very late in 1954 with the GearStart Ultramatic, which was something of a prototype for 1955’s Twin Ultramatic. Prior to that, it was the same Ultramatic (more or less) as originally introduced in the 23rd series with the under-car filler.
