That would be the 4L60E / 4L65E transmission.
Assuming that they are both 4wd or both 2wd and the same model transmission (4L60E), they are interchangeable.
That would be the 4L60E transmission. The 3/4 tons used the 4L80E
1/2 tons have a 4L60E 3/4 tons have a 4L80E
YES
too much
700R4 from 1986 to 1992 should work
I believe it is a 4L60-E, the upgraded 700-R4, although I do not know for sure.
type of fluid for 5 speed manual transmission
Yes as long as the 1999 is not a classic model.
If it is an automatic transmission, Dexron III or Mercon are both acceptable.
It does not have 1. It is all computer controlled.
