sounds like you should start by dropping the pan and changing the filter, put cheap fluid in it or reuse the old fluid if its not too bad bring it to a shop and have a transmission flush performed with a good flush machine your valve body is sticking and this should clear things up please rate -jeff

SOURCE: transmission problem
Two possibilities, one the valve body needs to be replaced. This is very common, and the usual symptoms are delay into reverse, and sometimes second also. The other is a loose input shaft nut. This has become more common on the 2000 to 2002 models, im not sure why though. The nut can be accessed by removing the transmission end cover. The input shaft is the one on the left, it uses a thin wall 23mm socket. The old nut should be removed and discarded, install a new nut and torque to spec (yes this is very important) then reinstall the end cover which is actually harder than it sounds. In the case of the valve body you need to drive normally up to 20 miles to reset the transmission adaptive settings. The input shaft nut does not require this, but it is a good idea. To clear the adaptives you will need to disconnect the battery for about 10 min.
