I have a 99Z w/3-4K on a new clutch and pressure plate. Recently,it started "slipping" under load, but not in first gear. This only happens under acceleration in gears 2-6. It takes off good in 1st, then car skips 750-1000 rpm halfway thru each of the rest of the gears,but catches and goes. Where doI start trouleshooting?

 

Have you checked the fluid level in the hydrolics?

 

yes,fluid level is good.

 

help???!!!
