Maybe a dumb question, but I'd rather ask a dumb question rather than screw something up.....
I have a 2003 Chevrolet 2 wheel drive crew cab with the 6.6 L and 5 speed Allison automatic.
I think I am understanding it that I have a spin on filter as well as a filter in the pan.....am I correct?
If indeed the spin on filter is a transmission filter, should I fill it with transmission fluid before installing the new one, similar to the idea of filling a fuel filter before installing it?
Sorry for the dumb questions....never had a truck with a spin on transmission filter.
You can, but you don't have to. I would do it just to limit fluid loss from the change.
