1986 maxda b2000 se5 transmission sewms to be slipping on hills. How much of what kind of fluid goes in this transmisaion

 

If this has a manual transmission, it's more likely your clutch is slipping and needs replaced.

 

Aight thank you / im still curious about the fluid type and the amount of fluid it takes

 

The 1986 Mazda B2000 was not a "Ranger", it was an import, 1994 and up B-series were same as Rangers

Not sure which engine it has or transmission but a 1986 manual transmission would use 80-90w gear oil, for sure, and about 4.5pints bone dry, so 2 quarts plus a little

But manual transmissions don't "slip", its impossible, clutches slip
