i have had some problems with my tranny over the past year.

when i back out of driveway, when i put in to drive it wont go forward till i hit the gas and it jumps when i do that.

and it shifts bad sometimes and i have noticed a loss in power.

when sitting still the truck shakes like a SOB.

and here yesterday i pulled out of my driveway and the SOB died on me and i started it back up and it ran about 2 miles till i parked it.

sat in parking lot with it running for about 8 minutes and pulled out and it made the worst noise you can think of and it died again.
(sounded like a POS car that has bad brakes and is trying to stop)

and ever since then it has felt like it is pulling a bit while i try to accelerate and sometimes even on decel.

any ideas on what is wrong?
