what type of fluid do i use in my 1988 gmc k1500 5-speed manual transmission and transfer case?
 
thats what i thought but a few people have told me i have to use a special gm fluid
 
if anyone knows for sure please let me know i just bought this truck and i want to change fluids
 
My 1998 k1500 calls for dex III in the transfer case, I think they used the same t-case during that time span. I changed mine out last fall so far no problems. Sorry cant help you on the tranny I have an auto.

Special fluid is usually with the Autotrac units (with Auto 4WD option) which I don't think was available in 1988.
