I was cruising around 80 at 3 grand, started feeling like the engine was revving slightly higher (few hundred rpm's) than usual at that speed and feeling like the trans was starting to fight back. I've had transmissions die on me a few times, so I know when things aren't going right. Suddenly it felt like the trans slipped briefly, then came out of OD and went into 3rd. This is a non-LU trans. I got off the highway and took back roads home for 10 miles, no problems. I pulled over and checked the fluid, it looked and smelt fine. Pulled on the TV cable several times, to possibly clear any junk that might be in the valve, but no change. I happen to have a pressure gauge hooked up and there was no change or fluctuation in the pressure when all this happened.
So now, with the gear selector in D it won't shift past 2nd, and with the gear selector in OD it won't get past 3rd. I have not driven the car since parking it after this. I was just glad to make it home.
Any ideas on what to check or what would cause this?
One more note: I ran the car on a chassis dyno for the first time just before this. See attached. I've got some tuning to do.
