Re: my car has know power in drive but in park it runs fine
Symptoms sound similar to restricted exhaust or low fuel pressure.
However, given you just did a tranny swap, I'm guessing the cause is there.
What kind of tranny is it, manual or automatic?
If manual, sounds like your clutch may not be releasing properly. If automatic, sounds like it could be torque converter issues.
If you find nothing in tranny, unhook your exhaust prior to catalytic converter and see if it fixes it. If not, check your fuel pressure with a gauge. you can rent one from autoZone of you don't own one.
