Car will immediately engage in all gears when first starting - within 3 minutes it will no longer engage in any gears - with substantial reving it will slightly move forward in drive - does this really sound like speed sensor??

Sounds more like valve body or shift control solenoids.......something has lowered clutch engagement line pressures.

It's weird - I can drive 100 yards up and down the street three times and then around the 4th time the severe slippage begins......let it sit for 5 minutes and it will do the same thing again except only 2 or 3 time up and down the street......I replace both shift solenoids 6 months ago and it has been fine. I did end up letting it sit for 6 weeks though and that's when this issue started.........I am not looking forward to dropping the pan again though. If I really push the issue on the slipping there seems to be some smoke and transmission fluid smell coming from the back of the engine and the fire wall on the drivers side......
