90 Suburban, drives great, auto tranny wont shift unless I let up on gas in 1st, 2nd
I just swapped for a decent running 90 GMC Suburban, 350, automatic, 4x4. Starts and runs and drives great, except...
When I am driving it, it runs up in the rpms great but wont shift into 1st or 2nd unless I let off on the gas. And sometimes overdrive. What causes this and how do I fix it?
Yes, the tranny fluid is full, properly checked when hot/flat spot, idling.
