When vehicle gets to operating temperature, the transmission seems to slip, never when cold. It slips at the end of first gear, through the whole second gear and in the begining of third gear. Never slips at high speeds. Slips when driving it straight or turning. Does not do it all of the time. I have never changed ATF fluid or filter. When it slips it feels like you are driving over cracks in the road, it is not a severe sliping.


Thanks

i would suggest changing the fluid and filter while youve got the pan off check the magnet inside the pan for chunks of metal.
a build up of fine metal powder is normal.
after changing filter and filling fluid get some friction modifiers to the fluid
