904 just gave up

Fred
IIRC you are splitting gears with that GV right?
If yes,
they require a good amount of driveshaft rpm to stay engaged. They do not work well with hiway gears at slow speeds. When slowing down,they can lose pressure and drop into neutral for a bit and then bang into direct. So just a heads up if you were in a split gear and forgot to disengage it.
When fresh mine could stay engaged at a stoplight, but as it aged it would drop out.
With 4.30s it never dropped out on me, and I could ask for a split right on the start line, and it would give it to me as soon as it had built up pressure.
With 3.55s I don't usually ask for a split below 30 mph
I'm not using their little control module.
