I just got the fly wheel replaced. When i got it back, the trany was slipping and i got tha P0720 code comming on. I replaced the speed sensor at the back of the trany and checked the whireing and conectors up to the top of the trany. The condition is still there. What should i do next.

Hello, I'm Chris.
Was the original flexplate (flywheel) cracked?
Which gear was slipping (engine rpm increasing but vehicle speed not increasing equally)?
Do you have a 4R70/75E transmission or a torqueshift transmission, if you do not know I can help?
The flywheel god mangled by a bad starter. The trany slips at low rpm. When it is above 2500 rpm, it dos not seems to slip, all do on a copple of ocasion it would not moove at all, and then after hidling for a while it would work after 2500 rpm. Som other time it works a bit better, just a slit slip and it would guet in to gear. Where do i find what tipe of trany it is?
Open your drivers door and look at the label in the door jam. on the bottom right of the label, it says TR. Under TR will be a B or Q or T. Just reply once you get a chance to check this?
Is the trans fluid still ruby red with little to no odor?
The fluid is farely dark and it was replaced a cople of months a go the letter Q is on the sticker. I just checked the fluid and it seamed to have too much. So i tried to remouve som by disconecting the cooler hose. Notting was comming out. So i put it in drive with the brakes on and reved it up but notting was happening. I did that a few tomes. On the forth try i finally got som tork and i also got som flow. I took out about a liter. Then the levle red half way in the cold atched section of the dipstick. I tried to mouve the van it allmost responded normaly with a slite slip up to about 1200 rpm and then a cople of minutes later, it did not want to go in geer and now the levle seems low.
After sitting for a cople of hours, i start the van, put it in revers, it went in gear and i was able to drive backword out of the shope but when i put it in drive to park it beside the shope it did not want to go in gear, tried reverse, notting. I was in the midle of the road so i put it in drive and pushed it forward about two feet then press on the gas pedal and it whent in gear and started to go forward at about 1200 rpm. I am not sure what is happening so i am giving you all the details hopping that somthing might help you.
Thanks for all the information.
You need to check the wiring harness on top of the trans to see if it has been crushed between the engine and transmission. If that is okay then you need to remove the transmission pan and check the fluid and pan magnet for debris and metal shavings. Also check that the filter is firmly attached and it is not double gasketed. If the pan is full of metal then it is time to stop there and overhaul the transmission. If the fluid is nasty dark and has a burnt odor then it is time to stop there and overhaul.
With just the previous repair,I believe they may have not seated the torque converter correct and it has cracked the pump which has reduced the available pressure which is why you are having a hard time getting the van to move. Lower pressures result in burnt up clutches as well.
