well ive put 50,000 on my truck sense i bought it and figured it was time to change the tranny fluid. i have the 4eod and wondered how many quarts i should buy, im doing the filter. i know my 70 mustang took 3 quarts but looks like the pan on my truck is bigger.

 

over 2 gallons.

you need to drain pan, converter and replace the filter and fluid.

get a big pan for converter where most of the fluid is.

do a search on this much discussed question if you need more info.

 

16-18 quarts comes to mind.

thanks. seems like a fun morning for me. also do i have a REUSABLE ELASTOMERIC TRANSMISSION FLUID PAN GASKET. ...

 

buy a filter and the gasket comes with it.

 

well finally had a no wind day so i changed my fluid and filter. what a pain. thought i could lean the pan enough to get most of the fluid out, naa, ended up holding it until last bolt was out then dumping it in the container, wasnt to bad. funny though the filter was laying in the pan. i know the pan holds it up but figured it shouldnt have just fall down with the pan. really nothing in the pan and very little black, like really super fine metal, around the big magnet inside the pan. so it looked good. but its done and seems to shift a little better. the only funny thing now is that the dipstick reads at the top of the hexed marks but only on that side, on the other side of the dipstick it doesnt read. i guess thats the way it suppose to work and yes i even drove it a few miles and rechecked it.

 

you did drain the torque converter i hope.

 

Are you checking it with the truck running?

 

...... and warmed up?
