Changed 91 R/T 1/2 shafts oil leaked - how to check/top off

[Wwweaty]

Know where the fill hole is located?

What is that stuff? Gear lube?

Thanks

Left side of trans, remove left front wheel and splash shield, rubber plug.

Factory fill is 5w30, but synchromesh or Redline MTL are good alternatives.

Easier to remove the reverse light switch, pop the rubber plug out the side and pour in the top until its flowing out the side. Let gravity work for you, not against you.

Thanks guys.
I added half a quart of Marvel Mystery Oil and it shifts so silky smooth now.

Becareful what oil you put in, it could attack and damage the fiber synchro's and brass rings.

The manufacturer did not say it would be a problem.
