I need to have the tranny fluid changed out in the truck but im not sure what to use? the book at work gave me some out of the box number. what are you guys running? this is in my 87 with a t-19

either 80w90, 75w90 gear oil or 15w 40 synthetic motor oil

i thought it had to be a specific type of oil? but any of those will work?

I asked this one last week, group concensus seemed to be 80-90w as bw's recommendation

NAPA told me ATF in my T-19????

ATF in the ZF5. 80w90 in t-19 for heavy towing and temps above 32*F. SAE 50 below 32*F. These were specs from borg warner. I will see if I can dig up my papers and post them.
