slipping and stalling.. 2.8 700r4

on the way home I noticed the transmission was slipping 2nd and 3rd while going up a hill. I parked. then when I tried to drive again the car dropped rpm and didn't move unless i let off the gas. even in neutral the car jumps rpms. sometimes when it drops rpms I hear a high pitch whistle sound. checked the tranny fluid to be bone dry. added 2 quarts and didn't change a thing. any ideas what I'm looking into? thanks.

A rebuild

Sounds like the clutch piston seals are smoked

Might want to go to youtube and watch the full series of videos by transmissionbench... very informative even if a bit repetitive and slow (don't need to watch every one of 17 pan bolts being loosened for example). Trans rebuild isn't magic or rocket surgery or anything; you can do it yourself most likely.

Yep, it is shot. Sounds like something besides the transmission there. Maybe vacuum leak, TPS going out.

Have you been leaking trans fluid? It must have gone somewhere. Definitely smoked the trans.
