Check to see if you broke the tranny oil pump teeth / tabs off. If you didn't line them up with the converter snout properly - and forced the unit together while bolting it to the engine, they may have broken off.
Just one guess from me.

1. Check fluid level 2. Is the kick down all the was forward on the transmission when you adjusted the kick down? 3. Is the shift lever 100% in the low when you adjusted the shifter? 4. Does the transmission go down into first when you completely stop?
Why cut the exhaust it should unbolt from the manifolds or headers

The kickdown wouldn't have anything to do with losing 2nd and 3rd gear after a small burnout would it? The car wouldn't move when put into 2nd or Drive. I had to drive it back home in 1st only. But the next day all gears were back. Christine?

Yeah I'll give that a shot. But it doesn't explain losing 2nd and drive after a small burnout. Or why it came back after sitting. That to me is the bigger problem. It wasn't that it wasn't shifting to 2nd. But if I put it in 2nd or drive it wouldn't move. Had to drive it 10 miles in 1st. I did play with the kickdown adjustment quite a bit. With little to no effect. But when it gets warm enough here. I'll try disconnecting the cable and see if that changes anything. Way to cold here to try that now :)Thanks for the help guys

When I let off I went to give it gas and it went nowhere. > If you are at a high vehicle speed in 1st gear, it will feel like it is in neutral. To test for that, let the vehicle slow down to approx. 10 mph - then open the throttle - if the engine pulls the car - you were stuck in 1st.
Losing gears and then "getting" them back sounds like valve/s hanging up - another guess. That is why you need to get a few gauges. Don't be intimidated by auto transmissions, they work on pressure. Hang a low pressure gauge on the governor port and operate the vehicle up to the highest speed you are comfortable - gov. psi should closely approximate vehicle speed. If it remains very low or does not move then that will cause you to remain in a lower gear. If it tracks like it is supposed to - you could have the 1-2 shift valve and governor plug hung up in the valve body or too much throttle pressure. Too much throttle pressure can be caused by that cable adjustment or the baseline adjustment on the valve body. The importance of testing pressures - narrows your focus. Dirt in an auto trans is as much an enemy as it is in an engine. In a trans it is not uncommon to cause your complaints of now I have 2nd and now I don't. The burnout likely had nothing to do with it unless you put more dirt in the trans by causing some failure.

The kickdown is adjusted to be all the way back when the throttle is fully open. Not the best way to adjust it; as advised earlier, disconnect the cable at the trans lever and allow the lever to come full forward then take it for a moderate drive and see if the symptoms disappear.

Kickdown linkage doesn't explain that it wouldn't move in D or 2nd. Or did I miss something. Ya gotta start somewhere, with a mixed bag of defects it's wise to start at square one.

Its like an electrical job with 5 different problems as when I get them I pick one problem and start troubleshooting it first. And many times you end up fixing all the problems. If you try to think of fixing all of them at the same time you end up not thinking straight. Ron
