More 4.4 Transmission issues :(

[Cbirchem0724]

I have not been able to drive my x5 for almost a year now because I am worried I might do more damage to the transmission and I don't have 6K to spend on a tranny with the X5 isn't even worth that. Anyway, After driving around for a while and letting the tranny heat up I am getting a horrible jerk from a stop. If I stop at a light then the light turns green I go to hit the gas and it revs a bit and then jerk! off she goes. I also notice this when shifting from reverse to drive. I have to wait 30 seconds or so before hitting the gas, also slow to shift when cold from 1-2.

I have a 2001 x5 with a 4.4
