Question about 1990 Ford F250
Well there are a few different transmissions they put in this truck.
Borg-Warner T-18 4speed takes SAE 80W
Ford S5-42 ZF 5 speed take Mercon 5
Mazda M50D 5 speed with overdrive takes Mercon 5
Mtsubishi FM132, FM146 5 speed with overdrive takes SAE 80W
It looks like they all take between 3 and 4 litres. You may have to call the dealership with the vin number to find out which transmission is in it but you could also just pull the drain plug out just a little bit and if the fluid is red then its mercon 5, if its brown and really thick fluid then its SAE 80W
