Thread: no gears but reverse

Greetings! So I have a 99 gt,& the other day,@ a stop,I started to go,& the gear slipped. About 400ft,I lost 3rd,&4th. was on way home in 1st,&2nd,w/shudering,&slipping,&high rpm's between 1st,&2nd. Another couple miles,I totally lost all gears,&made it home in reverse. I jacked up front end, put it in gear,& the wheels turned,but I could stop'em w/my foot. Please trouble shoot this for me. Thankyou,
C.
