Dodge truck transmission fluid type - 1987 Dodge D150

SOURCE: transmission

If the transmission is the 3 speed auto,just Dexron 2 or 3.If it's the 4 speed overdrive trans,it should use Mopar fluid(buy at the dealer) that is highly friction modified,or use Dexron 2 or 3 and LubeGard highly friction modified fluid supplement.The worst that can happen if these fluids aren't used,is harsh shifting,sometimes upshift shudder,and downshift bumps.These symptoms really don't damage anything,but are extremely annoying.

SOURCE: Steering gear fluid capacity and type of manual trasmission fluid?

Hello Dave,
I own a 1988 Ram 50 5-Standard and will go off my own experiences to answer this question.
I use a synthetic 80W transmission fluid.
If you know what is/was already in there; my recommendation is not to change the grade of oil in the transmission unless it is necessary because of driving conditions or vechicle requirements (i.e. towing/hauling/efficiency).
Anyway the Ram 50 Manual 4 & 5 Speed transmissions take a range of fluid grades from 70W-90W. You can use this in both conventional and synthetic oils.

For the power steering, universal power steering fluid works the best, and I honestly don't know the exact amount to put in Ram 50, but may I suggest you purchase ~20oz. Fill it half with half the bottle, then check the dipstick, then put in half of that half-bottle (a quarter of the bottle in), check, and repeat until you get it to the appropriate level.

Manual 6 quarts
Automatic depends on why it's being added. If bone dry try 8 quarts and check. Always check warm in no gear, if you can't be carefullllll not to over fill. Atf +4 is what dodge automatic. take

SOURCE: dont know if i should check transmission fluid with truck running

if its an automatic pull the dip stick out and it should be stamped on the stick. it will most likely be in park on level ground at operating tempature. if its a manual then while its level pull the fill plug out of the side of the trans it will be about half way up or so. the fluid should be at about the level of the fill hole on the side.

sounds like inspection cover to trans hitting flexplate
