Without speed sensor all PCM shifting logic is out the
window. 90% of the tables are MPH based. If you still
see zero MPH then get under there and check wiring
and connectors.

Fix the problem you know you have, and then see if
you have any left.

we are trying to help you with the transmission only have 3rd gear this means that the trans has no power with both solenoids off gives you 3rd gear with the solenoids having no power this will give you 3rd gear most likely the trans is unplugged could have happened when the mount broke if it hit the tunnel hard enough or it could have split the wiring harness which goes across the top of the tranny and could have gotten pinched between the tranny and the tunnel

No NONSENSE How would you know that you dont have any codes without scanning it. I have scanned many a car with no check engine light that did indeed has codes.
As for the VSS is the speedometer working ?
However no VSS would be more likley to leave you with late shifts and or no shifts while starting in first gear not third. Check wiring and harness and plug also check fuses

ok thanks! so i went out there and i checked the VSS (btw no my speedo is not working) and it seems fine. not broken or anything.

Ok so with me checking the harness and plug do i have to pull the tranny out?

this may sound dumb but did you check the fluid level? Mine started in 2nd and would only go to 3rd, no 4th, and it was about a quart or so low. I shut the car off topped it off and everything went back to normal. My speedo worked though.
