So I’ve got a 91 Burb V1500. TBI 350 with a 700R4. Both rebuilt within the last 30k miles. When driving down the freeway in OD it “hunts” and struggles to pick between 3rd and 4th. Not super rapid but fast enough to be an issue. I’d say if you matched stock blinker speed, that’s how fast it switches between the two.

Is this just a TV Detent adjustment issue? Or low fluid?
