Check to make sure you have enough tranny fluid in the car, don't ask me why or how, but mine was doing the same yours was, would work only when it got kinda hot, I drained tranny fluid and readded and it started working like new. Remember when filling tranny on a 5 speed you have to have all 4 wheels off the ground in order to get the righ amt of fluid in there.

 

i tought about that but when i checked it the car was on flat surface and fluid was coming out. I added 2qt and a half. So , i thought it wasn't it. I will go and buy some fluid and try it over the weekend.

 

If you want that extra bit of fluid, when you fill it, lower the front of the car lower than the rear, this will allow a little extra bit of fluid in the tranny.

 

i final filled the transmission full and the vss is still jumping around. I also checked to see if the wires were ground and they seemed ok.

 

I am having this exact same problem did u find out what it was???????????????????? PLEASE HELP ME!!!!!!!!

 

you should start a new thread, but anyway you may need to change the VSS.

 

I know this has thread has been idle for a while. Just in case you haven't fixed the problem yet here goes. Your descriptions of testing wires are very vague. Sensor is probably 3 wires. 5 volt sensor feed, Signal wire to ecu, ground. should only have power to one wire and it should be 5 volts. The most common problem after swap is gound. Check them close
